restore_error_handlerRestores the previous error handler function

返回值

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. ";
}

$serialized 'foo';
set_error_handler('unserialize_handler');
$original unserialize($serialized);
restore_error_handler();
?>

以上例程会输出:

Invalid serialized value.

注释

Note:

Calling restore_error_handler() from the error_handler function is ignored.
