“ pdo_mysql”已禁用，我无法将其启用。 我在iMac 7.1 OSX 10.6.8上安装了MAMP 3.0.4版

Question

“pdo_mysql” is disabled and I can't get it enabled. I have MAMP v. 3.0.4 installed on my iMac 7.1 OSX 10.6.8. On my phpinfo page I can see that the only PDO enabled is sqlite. If I look in my php (5.5.10) extensions folder I do see the pdo_mysql.so file (as well as one ending with .a). But if I go to the php.ini file the both the extensions folder path and the extension=pdo_mysql.so are there and correct. It feels like maybe my Mac is using another php.ini file but how do I find that out? Does anyone have any tips on how I can get the PDO enabled?

Answer 1

I've been struggling with this the whole weekend and finally solved it. Turns out that the php.ini is pointing to a non-existing "extensions dir". Create a phpinfo() file and look at the value of this field:

I noticed that in the mamp php installed folder there is a no-debug-non-zts-20131226 folder, which is different from the value shown in the phpinfo(). What I did was to clone this folder and changed the name to the value of the phpinfo(). Probably you could modify the php.ini file but I didn't want to.

Hope this helps.

In my case I was using PHP 5.4 but the value in the php.ini was pointing to the extensions folder of PHP 5.5. I simply changed the php.ini settings and restarted MAMP.

php.ini

extension_dir = "/Applications/MAMP/bin/php/php5.4.34/lib/php/extensions/no-debug-non-zts-201005‌​25"
