$php_errormsg

(PHP 4, PHP 5)

$php_errormsg — The previous error message

Opis

$php_errormsg is a variable containing the text of the last error message generated by PHP. This variable will only be available within the scope in which the error occurred, and only if the track_errors configuration option is turned on (it defaults to off).

Informacja: This variable is only available when track_errors is enabled in php.ini.

Ostrzeżenie

If a user defined error handler (set_error_handler()) is set $php_errormsg is only set if the error handler returns FALSE

The track_errors parameter is PHP_INI_ALL, so you can use code like this:





<?php


ini_set('track_errors', 1);





$result = @do_risky_thing();


if (! $result) {


    echo '<p>Error' . htmlspecialchars($php_errormsg) . '</p>';


}





ini_set('track_errors', 0);


?>

Note: This variable doesn't seem to get populated if you're running Xdebug.
