From: kevin at les-tilleuls dot coop Operating system: Mac OS X PHP version: 5.5.3 Package: PDO related Bug Type: Bug Bug description:PDO MySQL driver does not escape properly backslashes
Description: ------------ PDO MySQL driver does not escape backslashes in string. The MySQL doc indicates that backslashes must be doubled to be escaped http://dev.mysql.com/doc/refman/5.6/en/string-literals.html The driver does not do that. See the script above. Should this escaping be done by PDO or a higher layer like Doctrine DBAL? Test script: --------------- <?php define('DSN', 'mysql:dbname=testdb;host=127.0.0.1'); define('USER', 'root'); define('PASSWORD', ''); /* DATABASE STRUCTURE CREATE TABLE `test` ( `test` varchar(255) NOT NULL, PRIMARY KEY (`test`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; */ $dbh = new PDO(DSN, USER, PASSWORD); $data = '\\' . uniqid(); $stmt = $dbh->prepare('INSERT INTO test(test) VALUES(:data)'); $stmt->execute(array('data' => $data)); $stmt = $dbh->prepare('SELECT test FROM test WHERE test LIKE :data'); $stmt->execute(array('data' => $data)); var_dump($stmt->fetchColumn()); $stmt = $dbh->prepare('SELECT test FROM test WHERE test LIKE :data'); $stmt->execute(array('data' => str_replace('\\', '\\\\', $data))); var_dump($stmt->fetchColumn()); Expected result: ---------------- string(14) "\521f3f450f597" bool(false) Actual result: -------------- bool(false) string(14) "\521f3f450f597" -- Edit bug report at https://bugs.php.net/bug.php?id=65583&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65583&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65583&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65583&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65583&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65583&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65583&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65583&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65583&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65583&r=support Expected behavior: https://bugs.php.net/fix.php?id=65583&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65583&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65583&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65583&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65583&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65583&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65583&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65583&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65583&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65583&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65583&r=mysqlcfg
