note 117665 added to mysqli.construct

A friend of mine encountered a sudden bug with CMS Piwigo. I discovered that : - He had a hosting rule to use PHP 5.6. - The hoster uses 5.6.6, verified using phpinfo();. - The CMS declared a database name parameter as null. That gallery CMS was unable to connect to MySQL and left only a warning message about it. We tried to revert back to PHP 5.5, the CMS worked again. Then we switched back to 5.6.6 and changed those lines : $dbname = null; $mysqli = new mysqli($host, $user, $password, $dbname, $port, $socket); to $dbname = ''; // Use an empty string, not null $mysqli = new mysqli($host, $user, $password, $dbname, $port, $socket); It worked! So if you made the same mistake, using null where the manual invites to use an empty string, you should consider correcting your code. ---- Server IP: 72.52.91.14 Probable Submitter: 82.246.145.138 ---- Manual Page -- http://php.net/manual/en/mysqli.construct.php Edit -- https://master.php.net/note/edit/117665 Del: integrated -- https://master.php.net/note/delete/117665/integrated Del: useless -- https://master.php.net/note/delete/117665/useless Del: bad code -- https://master.php.net/note/delete/117665/bad+code Del: spam -- https://master.php.net/note/delete/117665/spam Del: non-english -- https://master.php.net/note/delete/117665/non-english Del: in docs -- https://master.php.net/note/delete/117665/in+docs Del: other reasons-- https://master.php.net/note/delete/117665 Reject -- https://master.php.net/note/reject/117665 Search -- https://master.php.net/manage/user-notes.php
