1.2.938. PHP Handlers Usage

PHP has a number of handlers that may be replaced by customized code : session, shutdown, error, exception. They are noted here.

The example is adapted from the PHP documentation of set_error_handler().

<?php
// error handler function
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting, so let it fall
        // through to the standard PHP error handler
        return false;
    }

    switch ($errno) {
    case E_USER_ERROR:
        echo '<b>My ERROR</b> [$errno] $errstr<br />'.PHP_EOL;
        echo '  Fatal error on line '.$errline.' in file .'$errfile;
        echo ', PHP ' . PHP_VERSION . ' (' . PHP_OS . ')<br />'.PHP_EOL;
        echo 'Aborting...<br />'.PHP_EOL;
        exit(1);
        break;

    case E_USER_WARNING:
        echo '<b>My WARNING</b> ['.$errno.'] '.$errstr.'<br />'.PHP_EOL;
        break;

    case E_USER_NOTICE:
        echo '<b>My NOTICE</b> ['.$errno.'] '.$errstr.'<br />'.PHP_EOL;
        break;

    default:
        echo 'Unknown error type: ['.$errno.'] $errstr<br />'.PHP_EOL;
        break;
    }

    /* Don't execute PHP internal error handler */
    return true;
}


// set to the user defined error handler
$old_error_handler = set_error_handler("myErrorHandler");

?>
