 Posted: Fri 07 Mar '25 17:36 Post subject: Getting php GD to load - Win11 dev host |
 |

I have tried many things but I cannot get php GD to load on my Win11 dev environment. I have done considerable research, all offering 'sure-fire solutions', but all have failed. Trying all this advice has led to many combinations of attempts all to no avail. I get no error, just GD doesn't load.
[Environment]
Windows 11
Apache/2.4.63 (Win64)
PHP/7.4.33 (I have different versions of php as part of migration to 8.4
[php.ini]
extension=gd is uncommented and tried as both 'gd' and as ...
extension=gd2
extension=php_gd2.dll is uncommented
extension_dir = "/php/php7-4-33/ext" is set and uncommented. Also tried as...
extension_dir = "c:\php\php7-4-33\ext"
Everything is not under /php due to switching between between different versions of php as a part of migration. I can update httpd.conf to report to different php interpreters and so test across versions and find break points.
I have also tried :
php_gd2.dll renamed as php_gd.dll without success
php_gd2.dll has been placed in c:\windows\system32
There is no error on restarting Apache. httpd -k restart completes just fine ... but GD steadfastly refuses to load. No error, just not there (checked by both php -m and phpinfo() output)
[httpd.conf]
PHPIniDir "c:/php/php7-4-33/"
LoadModule php7_module "c:\php\php7-4-33\php7apache2_4.dll"
Also tried
PHPIniDir "c:\php\php7-4-33"
PHPIniDir "c:\php\php7-4-33\"
I have no problem on live Linux boxes, but convincing GD to load on Windows dev is beating me at the moment. Any advice. I suspect it's something trvial!
One observation as I continue with this issue. phpinfo() shows:
| Code: | Configuration File (php.ini) Path no value
Loaded Configuration File C:\php\php.ini |
Odd that the php file path has 'no value', yet the correct php.ini is loaded. How is possible to load the correct file without knowing its location?
Final observation...
php -m does NOt list GD. But phpinfo() is now showing GD support enabled and it is indeed working. Somehow 'messing' with the httpd.conf PHPIniDir value resolved the issue, but interesting, php -m is telling fibs!
For anyone else having this challenge and finding this, I have...
[httpd.conf]
PHPIniDir "c:\php"
LoadModule php7_module "c:\php\php7-4-33\php7apache2_4.dll"
Note, you MUST NOT have a trailing "\" on PHPIniDir, i.e. "c:\php\" will break loading the php.ini. Also, my php7apache2_4.dll is nested a level down due to running/switching between multiple php versions.
[php.ini]
extension=gd
extension=php_gd2.dll
All the advice of the gd2.dll being renamed to just gd.dll seem wrong (although I think php 8 drops the '2'), copying to the php root directory, /system32, putting absolute paths on the location of gd2.dll and many other 'suggestions' proved not to work. Hopefully this 'adventure' may be of some use to someone else in the future 😊 |

Hi,
Wampserver configuration for PHP 7.4.33 used as an Apache 2.4.63 module
-- PHP 7.4.33
- php.ini
extension_dir ="E:/wamp64/bin/php/php7.4.33/ext/"
extension=gd2
-- Apache 2.4.63
- httpd.conf
PHPIniDir "E:/wamp64/bin/apache/apache2.4.63/bin"
LoadModule php7_module "E:wamp64/bin/php/php7.4.33/php7apache2_4.dll"
In the apache bin folder (E:/wamp64/bin/apache/apache2.4.63/bin/), there are symbolic links to some PHP 7.4.33 dlls and to its php.ini file:
<SYMLINK> icudt66.dll [E:/wamp64/bin/php/php7.4.33/icudt66.dll]
<SYMLINK> icuin66.dll [E:/wamp64/bin/php/php7.4.33/icuin66.dll]
<SYMLINK> icuio66.dll [E:/wamp64/bin/php/php7.4.33/icuio66.dll]
<SYMLINK> icuuc66.dll [E:/wamp64/bin/php/php7.4.33/icuuc66.dll]
<SYMLINK> libcrypto-1_1-x64.dll [E:/wamp64/bin/php/php7.4.33/libcrypto-1_1-x64.dll]
<SYMLINK> libpq.dll [E:/wamp64/bin/php/php7.4.33/libpq.dll]
<SYMLINK> libsasl.dll [E:/wamp64/bin/php/php7.4.33/libsasl.dll]
<SYMLINK> libsodium.dll [E:/wamp64/bin/php/php7.4.33/libsodium.dll]
<SYMLINK> libsqlite3.dll [E:/wamp64/bin/php/php7.4.33/libsqlite3.dll]
<SYMLINK> libssh2.dll [E:/wamp64/bin/php/php7.4.33/libssh2.dll]
<SYMLINK> libssl-1_1-x64.dll [E:/wamp64/bin/php/php7.4.33/libssl-1_1-x64.dll]
<SYMLINK> php.ini [E:/wamp64/bin/php/php7.4.33/php.ini]
<SYMLINK> php7ts.dll [E:/wamp64/bin/php/php7.4.33/php7ts.dll]
In httpd.conf and php.in, for paths, use slashes / and not backslashes. |

Thanks, however I'm not usig WAMP and I'm also on Windows (this is just a dev laptop, not a Linux server), so no WAMP config and no symbolic links, just httpd.conf (and additional .confs) and php.ini. I have always just installed Apache and then php. WAMP never seemed to help things.
I have GD working with php 7.4.33 but on switching to php 8.3.3 and 8.4.4 GD failed to load, but I need to do look further at why. Strange given it's the same php.ini 😔
My current problem is getting sockets working with 7.4.33 and extending 'Registered Stream Socket Transports' beyond just tcp and udp. So far, all the advice about uncommenting...
| Code: | extension=sockets
extension=php_sockets.dll |
have failed to get things working.
One step forward and another one back 😂 |

Hi,
For PHP 7.4.33 it is:
extension=gd2
For PHP 8.4.4 it is
extension=gd
| Quote: | | extension=php_sockets.dll |
Starting with PHP 7.2.0, you must not put "php_" at the beginning of the extension name, nor .dll at the end.
If we look at the "php.ini-development" files of the different PHP versions of https://windows.php.net/download/ we can see :
- PHP 7.4.33
;extension=fileinfo
;extension=gd2
;extension=gettext
- PHP 8.4.4
;extension=fileinfo
;extension=gd
;extension=gettext
- PHP 7.0.0
;extension=php_fileinfo.dll
;extension=php_gd2.dll
;extension=php_gettext.dll
Extract from: https://www.php.net/manual/en/image.installation.php
In Windows, you'll include the GD DLL php_gd.dll as an extension in php.ini. Prior to PHP 8.0.0, the DLL was named php_gd2.dll.

  Except that you can use it from PHP 5.6.40 to PHP 8.4.4 without any problem, and even have the same local site under several different PHP versions. |
