PHP - Stop displaying full path in errors

问题

Is there any way I can tell PHP to NOT display full path of file having any error in Error, warning or notice messages. I know I can disable errors; But, just to avoid any risk.

For example: My script returns an error which is displayed like:

Fatal error: Call to undefined function shell_exec1() in /home/[user]/public_html/index.php on line 1

I want to display it like

Fatal error: Call to undefined function shell_exec1() in ~/index.php on line 1

This way, It'll be safer way to display error messages while not exposing full path of file to bad guys.

Is this possible? How?

Just write your own error handler. see: http://www.php.net/manual/en/function.set-error-handler.php

function myErrorHandler($errno, $errstr, $errfile, $errline) {
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting
        return;
    }

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

    case E_USER_WARNING:
        echo "<b>My WARNING</b> [$errno] $errstr<br />\n";
        break;

    case E_USER_NOTICE:
        echo "<b>My NOTICE</b> [$errno] $errstr<br />\n";
        break;

    default:
        echo "Unknown error type: [$errno] $errstr<br />\n";
        break;
    }

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

set_error_handler("myErrorHandler");

As suggested above use custom error handler. BUT cut the path with the basename() to achieve what you want.
