restore_error_handler

Restores the previous error handler function

Description

true restore_error_handler()

Parameters

Return Values

Always returns true.

Examples

Example #1 restore_error_handler example

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

<?php
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:

Invalid serialized value.
