restore_error_handler

(PHP 4 >= 4.0.1, PHP 5)

Used after changing the error handler function using
set_error_handler(), to revert to the previous error
handler (which could be the built-in or a user defined function).

This function always returns TRUE.

Example 1. restore_error_handler() example

Decide if unserialize() caused an error, then
restore the original error handler.

function unserialize_handler($errno, $errstr)
{
    echo "Invalid serialized value.\n";
}
 
$serialized = 'foo';
set_error_handler('unserialize_handler');
$original = unserialize($serialized);
restore_error_handler();

The above example will output:

Note:
Calling restore_error_handler() from the
error_handler function is ignored.
