PDO drivers no value in Windows

Question

The php_pdo_mysql.dll can\'t be enabled in machine. I have set extension=php_pdo.dll and extension=php_pdo_mysql.dll enabled in php.in

Answer 1

On an Windows Server 2012, Apache 2.4, php 5.4 installation, after trying everything else changing this worked...

PHPIniDir "C:\php\"

to

PHPIniDir "C:/php/"

...guh.

Answer 2

I had this same problem when I upgraded to PHP 5.4. I had

extension_dir = "ext"

in php.ini and php -m was starting fine and reporting that it loaded pdo_mysql, but when I ran phpinfo.php through apache, the driver was missing.

I fixed it by changing the extension_dir to an absolute path. I'm guessing it got confused when running through Apache and made it relative to something else.

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "D:/php-5.4.11-Win32-VC9-x86/ext"

Answer 3

try the following: look for this in your php.ini and uncomment extension_dir = "ext"

; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
 extension_dir = "ext"

Answer 4

I got hints here:

http://wiki.cementhorizon.com/display/CH/Solution+-+Unable+to+load+dynamic+library+C+php+ext+php_mysql.dll+-+the+specified+module+could+not+be+found

I made sure that I set c:/php as a PATH variable and then moved the appropriate dlls into the c:/php directory (from the c:/php/ext directory).

All works for me now, though I'm not completely comfortable with moving things around the php directory.

Answer 5

I had this problem too. I have Apache/2.2.22 (Win32) PHP/5.3.23 on a Windows 7 machine. My solution was changing extension_dir = C:\Program Files (x86)\PHP\ext in the php.ini file to extension_dir = "C:\Program Files (x86)\PHP\ext". It just needed adding the quotation marks.

I also added the php directory to the CLASSPATH.

Answer 6

After change the php.ini configuration, need to restart Appche server in windows service. Then the extension module will be loaded. use following code to test :<?php print_r(get_loaded_extensions());?>
