Simpler test script: <?php $mysqli = new mysqli('localhost', 'root', 'password'); $mysqli->select_db('db'); Full Warning: 2015/11/04 16:58:17 [error] 20107#0: *2075 FastCGI sent in stderr: "PHP message: PHP Warning: mysqli::__construct(): (HY000/2002): No such file or directory in /var/www/enternum/public_html/test.php on line 2 PHP message: PHP Warning: mysqli::select_db(): Couldn't fetch mysqli in /var/www/public_html/test.php on line 3" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7-fpm.sock:", host: "localhost" ------------------------------------------------------------------------ [2015-11-04 14:50:35] rmoisto at gmail dot com Description: ------------ The select_db function does not work and produces a Warning when using a class that extends mysqli. This worked perfectly with PHP 5.6. As I have both PHP versions installed on this computer I switched between them several times to confirm this. I'm using PHP 7 RC6 that I compiled from source. The web server is nginx, using PHP with FPM. Test script: --------------- <?php class MyMysqli extends mysqli { public function e_select_db($db) { return $this->select_db($db); } } $mysqli = new MyMysqli('localhost', 'root', 'password'); $mysqli->e_select_db('db'); Expected result: ---------------- Database is selected. Actual result: -------------- Database is not selected. Also, the following Warning is written to the error log: PHP message: PHP Warning: mysqli::select_db(): Couldn't fetch MyMysqli in /var/www/public_html/test.php on line 4" while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7-fpm.sock:", host: "localhost" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70854&edit=1
