PHP 7 RC3 How to install missing MySQL PDO

Question

I am trying to setup webserver with PHP 7 RC3   Nginx on Ubuntu 14 04  for test purposes    I installed Ubuntu in Vagrant using ubuntu trusty64 and PHP 7 RC 3 from Ondrej Sur    https   launchpad net  ondrej  archive ubuntu php-7 0    I can not find the way to install MySQL PDO  PHP sees PDO class but not anything related to MySQL  like PDO  MYSQL ATTR DIRECT QUERY etc    Looks like there is no lib php7 0-mysql  by analogy with standard php5-mysqlnd and php7 0-fpm etc  from Ondrej   Section PDO in phpinfo     PDO support      enabled PDO drivers      no value   How can I get it

I had  pretty much  the same problem  I was able to see that PDO was enabled but I had no available drivers  using PHP 7-RC4   I managed to resolve the issue by adding the php pdo mysql extension to those which were enabled   Hope this helps

For thoses running Linux with apache2 you need to install php-mysql  apt-get install php-mysql   or if you are running ubuntu 16 04 or higher just running the following command will be enought  no need to edit your php ini file  apt-get install php7 2-mysql     If you are running ubuntu 15 10 or below   Edit your php ini file  it s located at  etc php  version  apache2 php ini and search for pdo mysql you might found something like this   extension pdo mysql so   Change it to this  extension pdo mysql so   Save the file and restart apache  service apache2 restart   Check that it s available in your phpinfo

If you are on windows  and your php folder is not in your PATH  you have set the absolute directory in your php ini  for example   extension dir    C  php7 ext    and uncomment   extension php mysqli dll extension php pdo mysql dll   Restart apache2 4 and it should work   I hope it helps

Had the same issue  resolved by actually enabling the extension in the php ini with the right file name  It was listed as php pdo mysql so but the module name in  lib php modules was called just pdo mysql so  So just remove the  php   prefix from the php ini file and then restart the httpd service and it worked like a charm   Please note that I m using Arch and thus path names and services may be different depending on your distrubution

User · Answer

First  check if your php ini has the extension enabled  php pdo mysql  and  php mysqli  and the path of  extension dir  is correct  If you need one of above configuration  then  you must restart the php-fpm to apply the changes   In my case  where i am using the Windows OS in the company  i really prefer OSX or Linux   i solved the problem putting this values in the php ini          extension dir    ext           extension php mysqli dll extension php pdo mysql dll          I hope this helps
