Req #71130 [NEW]: Allow PDO to lazy-connect

From: tom at r dot je Operating system: Any PHP version: 7.0.0 Package: PDO related Bug Type: Feature/Change Request Bug description:Allow PDO to lazy-connect Description: ------------ Currently PDO connects when an instance is created new PDO(....); will connect to the database at the point the PDO object is created. For performance reasons sometimes this is not required and due to the way a lot of frameworks work, will mean connecting even if a query is never made. To overcome this, PDO is often wrapped in a class which connects at the point a query (or prepare, or other database requiring function is called. See http://stackoverflow.com/questions/23595609/is-this-how-lazy-connecting-of-a-database-connection-is-supposed-to-be and http://stackoverflow.com/questions/5484790/auto-connecting-to-pdo-only-if-needed It would be better if PDO supported lazy connection as an option when the object is instantiated, for example: <?php $dbh = new PDO($dsn, $user, $password, PDO::LAZY_CONNECT); ?> Which would only connect to the database server when query(), prepare() or other similar functions are called. -- Edit bug report at https://bugs.php.net/bug.php?id=71130&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71130&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71130&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71130&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71130&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71130&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71130&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71130&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71130&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71130&r=support Expected behavior: https://bugs.php.net/fix.php?id=71130&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71130&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71130&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71130&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71130&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71130&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71130&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71130&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71130&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71130&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71130&r=mysqlcfg
