Geocoding: Location to Latitude/Longitude

BRADINO — Thu, 25 Sep 2008 17:09:20 +0000

Both Google and Yahoo offer free geocoding services. Geocoding is the process of getting the latitude/longitude coordinates for a particular address or location. With the latitude/longitude coordinates you can fun things like plot markers on a map, calculate distances between points, etc. I have created two simple standalone functions to geocode an address, one for Google and one for Yahoo. Both require an API key.

Google Documentation Google API Key Yahoo Documentation Yahoo API Key

// API KEYS

$googleKey = "INSERT-API-KEY";

$yahooKey = "INSERT-API-KEY";

// ARRAY OF LOCATION PARAMETERS

$params = array();

$params['address'] = "2470 E Street";

$params['city'] = "San Diego";

$params['state'] = "CA";

$params['zip'] = "92102";

// GEOCODING USING GOOGLE

PHP Mail using Zend Mail

BRADINO — Wed, 30 May 2007 04:33:04 +0000

This simple function is a simple usage of the Zend Mail functionality. The headers are all formatted nicely, slipping it past many more spam filters than standard PHP mail() function. Basically you just have to pass in an associative array of the required parameters. Many parameters are optional. This function does not have error trapping or input grooming/validation so depending on where you use it in your code, beware.

//FUNCTION TO SEND EMAIL VIA ZEND MAIL
function sendEmail($params){
ini_set('include_path', 'inc/');
require_once ('inc/Zend/Mail.php');
$mail = new Zend_Mail();
if (!empty($params['bodyText'])) $mail->setBodyText($params['bodyText']);
if (!empty($params['bodyHtml'])) $mail->setBodyHtml($params['bodyHtml']);
$mail->setFrom($params['fromEmail'], $params['fromName']);
$mail->addTo($params['toEmail'], $params['toName']);
if (!empty($params['bccEmail']) && !empty($params['bccName'])) $mail->addBcc($params['bccEmail'], $params['bccName']);
$mail->setSubject($params['subject']);
if (!empty($params['attachFile']) && file_exists($params['attachFile'])){
$at = $mail->addAttachment(file_get_contents($params['attachFile']));
$at->type = $params['attachType'];
$at->disposition = Zend_Mime::DISPOSITION_ATTACHMENT;
$at->filename = $params['attachName'];
}
$mail->send();
}

Download Zend Framework. One thing to keep in mind is that you can use the classes in the Zend Framework outside the framework itself.

PHP file function

BRADINO — Mon, 26 Feb 2007 05:08:42 +0000

file

(PHP 3, PHP 4, PHP 5)

file -- Reads entire file into an arrayDescriptionarray file ( string filename [, int use_include_path [, resource context]] )

Identical to file_get_contents(), except that
file() returns the file in an array. Each
element of the array corresponds to a line in the file, with the
newline still attached. Upon failure, file()
returns FALSE.

You can use the optional use_include_path parameter
and set it to "1", if you want to search for the file in the include_path, too.

// Get a file into an array. In this example we'll go through HTTP to get
// the HTML source of a URL.
$lines = file('http://www.example.com/');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

// Another example, let's get a web page into a string. See also file_get_contents().
$html = implode('', file('http://www.example.com/'));

Tip: You can use a URL as a
filename with this function if the fopen wrappers have been enabled.
See fopen() for more details on how to specify
the filename and Appendix N for a list of supported
URL protocols.

Note:
Each line in the resulting array will include the line ending, so you
still need to use rtrim() if you do not want the line
ending present.

Note: If you are having problems
with PHP not recognizing the line endings when reading files either on or
created by a Macintosh computer, you might want to enable the
auto_detect_line_endings
run-time configuration option.

Note:
As of PHP 4.3.0 you can use file_get_contents() to
return the contents of a file as a string.

In PHP 4.3.0 file() became binary safe.

Note: Context support was added
with PHP 5.0.0. For a description of contexts, refer to
Reference CLVIII, Stream Functions.

Warning

When using SSL, Microsoft IIS
will violate the protocol by closing the connection without sending a
close_notify indicator. PHP will report this as "SSL: Fatal Protocol Error"
when you reach the end of the data. To workaround this, you should lower your
error_reporting level not to include warnings.
PHP 4.3.7 and higher can detect buggy IIS server software when you open
the stream using the https:// wrapper and will suppress the warning for you.
If you are using fsockopen() to create an ssl:// socket,
you are responsible for detecting and suppressing the warning yourself.

PHP file_get_contents function

BRADINO — Mon, 26 Feb 2007 05:08:40 +0000

file_get_contents

(PHP 4 >= 4.3.0, PHP 5)

file_get_contents -- Reads entire file into a stringDescriptionstring file_get_contents ( string filename [, bool use_include_path [, resource context [, int offset [, int maxlen]]]] )

Identical to file(), except that
file_get_contents() returns the file in a string,
starting at the specified offset up to
maxlen bytes.
On failure, file_get_contents() will return FALSE.

file_get_contents() is the preferred way to read the
contents of a file into a string. It will use memory mapping techniques if
supported by your OS to enhance performance.

Note:
If you're opening a URI with special characters, such as spaces, you
need to encode the URI with urlencode().

Note:
context parameter can be skipped by NULL.

ChangeLog

VersionDescription5.0.0 Added the context support.
5.1.0 Added the offset and
maxlen parameters.

Notes

Note: This function is
binary-safe.

Note: Context support was added
with PHP 5.0.0. For a description of contexts, refer to
Reference CLVIII, Stream Functions.

PHP file_put_contents function

BRADINO — Mon, 26 Feb 2007 05:08:39 +0000

file_put_contents

(PHP 5)

file_put_contents -- Write a string to a fileDescriptionint file_put_contents ( string filename, mixed data [, int flags [, resource context]] )

Identical to calling fopen(), fwrite(),
and fclose() successively.

You can also specify the data parameter as an array
(not multi-dimension arrays). This is equivalent to
file_put_contents($filename, implode('', $array)).

As of PHP 5.1.0, you may also pass a stream resource to the
data parameter. In result, the remaining buffer of
that stream will be copied to the specified file. This is similar with
using stream_copy_to_stream().

Parameters

filename

The file name where to write the data

data

The data to write. Can be either a string, an
array or a stream resource (explained above).

flags

flags can take
FILE_USE_INCLUDE_PATH,
FILE_APPEND and/or LOCK_EX
(acquire an exclusive lock), however the
FILE_USE_INCLUDE_PATH option should be used with
caution.

context

A context resource

Return Values

The function returns the amount of bytes that were written to the file, or
FALSE on failure.

ChangeLog

VersionDescription5.1.0 Added support for LOCK_EX and the ability to pass
a stream resource to the data parameter

Notes

Note: This function is
binary-safe.

Note: Context support was added
with PHP 5.0.0. For a description of contexts, refer to
Reference CLVIII, Stream Functions.

PHP fread function

BRADINO — Mon, 26 Feb 2007 05:07:59 +0000

fread

(PHP 3, PHP 4, PHP 5)

fread -- Binary-safe file readDescriptionstring fread ( resource handle, int length )

fread() reads up to
length bytes from the file pointer
referenced by handle. Reading stops when up to
length bytes have been read, EOF
(end of file) is reached, (for network streams) when a packet becomes
available, or (after opening userspace stream) when 8192 bytes have been read
whichever comes first.

Returns the read string or FALSE in case of error.

// get contents of a file into a string
$filename = "/usr/local/something.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);

Warning

On systems which differentiate between binary and text files
(i.e. Windows) the file must be opened with 'b' included in
fopen() mode parameter.

$filename = "c:\\files\\somepic.gif";
$handle = fopen($filename, "rb");
$contents = fread($handle, filesize($filename));
fclose($handle);

Warning

When reading from anything that is not a regular local file, such as
streams returned when
reading remote files or from
popen() and fsockopen(), reading
will stop after a packet is available. This means that you should
collect the data together in chunks as shown in the examples below.

// For PHP 5 and up
$handle = fopen("http://www.example.com/", "rb");
$contents = stream_get_contents($handle);
fclose($handle);

$handle = fopen("http://www.example.com/", "rb");
$contents = '';
while (!feof($handle)) {
$contents .= fread($handle, 8192);
}
fclose($handle);

Note:
If you just want to get the contents of a file into a string, use
file_get_contents() as it has much better performance
than the code above.

fsockopen(), popen(),
fgets(), fgetss(),

PHP openssl_pkcs7_encrypt function

BRADINO — Mon, 26 Feb 2007 04:36:04 +0000

openssl_pkcs7_encrypt

(PHP 4 >= 4.0.6, PHP 5)

openssl_pkcs7_encrypt -- Encrypt an S/MIME messageDescriptionbool openssl_pkcs7_encrypt ( string infile, string outfile, mixed recipcerts, array headers [, int flags [, int cipherid]] )

openssl_pkcs7_encrypt() takes the contents of the
file named infile and encrypts them using an RC2
40-bit cipher so that they can only be read by the intended recipients
specified by recipcerts, which is either a
lone X.509 certificate, or an array of X.509 certificates.
headers is an array of headers that
will be prepended to the data after it has been encrypted.
flags can be used to specify options that affect
the encoding process - see PKCS7
constants.
headers can be either an associative array
keyed by header name, or an indexed array, where each element contains
a single header line.
Cipher can be selected with cipherid since PHP 5.

Example 1. openssl_pkcs7_encrypt() example

// the message you want to encrypt and send to your secret agent
// in the field, known as nighthawk. You have his certificate
// in the file nighthawk.pem
$data = <<<EOD
Nighthawk,

Top secret, for your eyes only!

The enemy is closing in! Meet me at the cafe at 8.30am
to collect your forged passport!

HQ
EOD;

// load key
$key = file_get_contents("nighthawk.pem");

// save message to file
$fp = fopen("msg.txt", "w");
fwrite($fp, $data);
fclose($fp);

// encrypt it
if (openssl_pkcs7_encrypt("msg.txt", "enc.txt", $key,
array("To" => "nighthawk@example.com", // keyed syntax
"From: HQ <hq@example.com>", // indexed syntax
"Subject" => "Eyes only"))) {
// message encrypted - send it!

PHP pg_escape_bytea function

BRADINO — Mon, 26 Feb 2007 04:30:42 +0000

pg_escape_bytea

(PHP 4 >= 4.2.0, PHP 5)

pg_escape_bytea --
Escape a string for insertion into a bytea field
Descriptionstring pg_escape_bytea ( string data )

pg_escape_bytea() escapes string for
bytea datatype. It returns escaped string.

Note:
When you SELECT a bytea type, PostgreSQL returns octal byte values
prefixed with '\' (e.g. \032). Users are supposed to convert back to
binary format manually.

This function requires PostgreSQL 7.2 or later. With PostgreSQL
7.2.0 and 7.2.1, bytea values must be cast when you enable
multi-byte support. i.e. INSERT INTO test_table (image)
VALUES ('$image_escaped'::bytea); PostgreSQL 7.2.2 or
later does not need a cast. The exception is when the client and backend
character encoding does not match, and there may be multi-byte
stream error. User must then cast to bytea to avoid this error.

Parameters

data

A string containing text or binary data to be inserted into a bytea
column.

Return Values

A string containing the escaped data.

Examples

Example 1. pg_escape_bytea() example

// Connect to the database
$dbconn = pg_connect('dbname=foo');

// Read in a binary file
$data = file_get_contents('image1.jpg');

// Escape the binary data
$escaped = pg_escape_bytea($data);

// Insert it into the database
pg_query("INSERT INTO gallery (name, data) VALUES ('Pine trees', '{$escaped}')");

PHP pg_escape_string function

BRADINO — Mon, 26 Feb 2007 04:30:41 +0000

pg_escape_string

(PHP 4 >= 4.2.0, PHP 5)

pg_escape_string --
Escape a string for insertion into a text field
Descriptionstring pg_escape_string ( string data )

pg_escape_string() escapes a string for
insertion into the database. It returns an escaped string in the
PostgreSQL format. Use of this function is recommended instead of
addslashes(). If the type of the column
is bytea, pg_escape_bytea() must be used
instead.

Note:
This function requires PostgreSQL 7.2 or later.

Parameters

data

A string containing text to be escaped.

Return Values

A string containing the escaped data.

Examples

Example 1. pg_escape_string() example

// Connect to the database
$dbconn = pg_connect('dbname=foo');

// Read in a text file (containing apostrophes and backslashes)
$data = file_get_contents('letter.txt');

// Escape the text data
$escaped = pg_escape_string($data);

// Insert it into the database
pg_query("INSERT INTO correspondence (name, data) VALUES ('My letter', '{$escaped}')");

PHP readfile function

BRADINO — Mon, 26 Feb 2007 04:25:09 +0000

readfile

(PHP 3, PHP 4, PHP 5)

readfile -- Outputs a fileDescriptionint readfile ( string filename [, bool use_include_path [, resource context]] )

Reads a file and writes it to the output buffer.

Returns the number of bytes read from the file. If an error
occurs, FALSE is returned and unless the function was called as
@readfile(), an error message is printed.

You can use the optional second parameter and set it to TRUE, if
you want to search for the file in the include_path, too.

Note: Context support was added
with PHP 5.0.0. For a description of contexts, refer to
Reference CLVIII, Stream Functions.
