restore_error_handler
(PHP 4 >= 4.0.1, PHP 5, PHP 7, PHP 8)
restore_error_handler — Restores the previous error handler function
Description
function restore_error_handler():
true
Pops the error handler that was active before the most recent call to
set_error_handler() off the internal stack of error
handlers and makes it active again, together with the
error_levels mask it was registered with.
The restored handler could be the built-in or a user defined function.
Calling this function more often than set_error_handler()
leaves the built-in error handler active; no error is raised.
Parameters
This function has no 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.
