restore_error_handler — Restores the previous error handler function

说明

bool restore_error_handler ( void )

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).

返回值

This function always returns TRUE.

范例

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();
?>

上例将输出：

Invalid serialized value.

注释

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