如何在Windows上为PHP安装PDO驱动程序？

Question

I installed Apache, PHP 5.6 and MySQL 5.7 on a Windows server.

In php.ini, I enabled the following:

extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_oci8_12c.dll
extension=php_pdo_mysql.dll
extension=php_pdo_oci.dll

(And restarted Apache)

But when I try to use PDO in my php page, it still throws the error:

Fatal error: Uncaught exception 'PDOException' with message 'could not find driver'

What do I have to do to get PDO installed?

Answer 1

The problem was the extension_dir directive did not work as a relative path. Changing from extension_dir="ext" to extension_dir="c:/phpinstall_path/ext" fixed the problem.

Answer 2

In my apache httpd.conf I have (note I have # as remmed out because it took me 1 hour at least). So I left it to show me how not to do it.

#PHPIniDir 'c:\apps\php\'
#PHPIniDir "C:\Apache24\~PHP_download\php-5.6.11-Win32-VC11-x64\"
PHPIniDir "C:/Apache24/~PHP_download/php-5.6.11-Win32-VC11-x64"

#LoadModule php5_module "c:/apps/php/php5apache2_2.dll"
LoadModule php5_module "C:/Apache24/~PHP_download/php-5.6.11-Win32-VC11-x64/php5apache2_4.dll"

AddHandler application/x-httpd-php .php

In the above folder (and seen below) I have these files:

And in that same folder, in the php.ini file I have the following block that are pdo-related, with the ones in force not remmed out with a ;

;extension=php_pdo_firebird.dll extension=php_pdo_mysql.dll ;extension=php_pdo_oci.dll extension=php_pdo_odbc.dll ;extension=php_pdo_pgsql.dll ;extension=php_pdo_sqlite.dll

then I have a phpinfo_xyz.php file for testing purposes only (read: delete it when you are done) that contains

<?php phpinfo(); ?>

Restart apache, point to that file from a browser and notice the following blocks similar to the following three.

...

In the first PHP picture above from phpinfo() , it was the getting the path right in httpd.conf that took the longest. That is why I left in the wrong path attempts seen in this Answer.

So it wasn't until Loaded Configuration File showed up decent that it had a chance.

Good luck. It was not fun. Half the problem was there were like 2 or 4 options of which original download to perform. Sadly I think it took me 2 or 3 hours all together. But I am not as smart as the rest of you.
