Custom Query (267 matches)

Reported by pierres, 12 months ago.

Some variables like $enable_eval are accessed even though they are only defined in config.php.example.

Adding a isset() check before accessing such variables would make the config file optional and wont rise any PHP warnings.

This would make it a little easier to directly use the xcache admin distributed with the package.

<?php

error_reporting(E_ALL);
set_error_handler('error');

function error($errno, $errstr, $errfile, $errline, $errcontext)
{
    echo "PHP ERROR - error n°" . $errno . ' : ' . $errstr . "\n";
    if (!class_exists('test42'))
        echo " - hit a bug, test42";
    die();
}
class test42 { }

require_once 'page_with_an_error.php';

?>

page_with_an_error.php:

<?php
function test(&$val) { }
$val = 'this is a test';

// Deprecated :
test(&$val);

?>

the custom error handler is catching the E_DEPRECATED error, but when cached, the error handler cant use any of previously existing objects (like test42 in this example).

Another testcase, that made my php5.3 to segfault :

<?php

error_reporting(E_ALL);
set_error_handler('error');

function error($errno, $errstr, $errfile, $errline, $errcontext)
{
    if (!defined('DISPLAY_ERROR'))
        define('DISPLAY_ERROR', true);

    if (DISPLAY_ERROR)
        echo "PHP ERROR - error n°" . $errno . ' : ' . $errstr . "\n";
}

// 1st error E_DEPRECATED inside page_with_an_error.php
include 'page_with_an_error.php';

// 2nd error
asort();

?>

'page_with_an_error.php' is the same file with the deprecated call by reference error.
