I have enebled gd extension by following this question: Fatal error: Call to undefined function: imagecreate()

Following is my php.ini:

extension=php_gd2.dll

But still getting error.

I tried changing php version, tried different php files but still getting error.

I tried running the application as administrator also.

I am using Windows 11.

I tried following code to check if gd extension is enebled.

<?php
if (extension_loaded('gd')) {
    echo "GD library is enabled.";
} else {
    echo "GD library is not enabled.";
}
?>

It returns: GD library is not enabled..

Why is gd extension is not being enebled?

. . In phpinfo(); it shows this:

GD imaging: Rasmus Lerdorf, Stig Bakken, Jim Winstead, Jouni Ahto, Ilia Alshanetsky, Pierre-Alain Joye, Marcus Boerger

Make sure you edited the _correct_ `php.ini`. If you're unsure which one is actually used, call `phpinfo()` and find out. — CBroe, Aug 08 '23 at 07:29
Also, you did restart the webserver after making changes, yes? — CBroe, Aug 08 '23 at 07:29
@CBroe I double checked everything. I have updated the question for `phpinfo();` response. — Hello World, Aug 08 '23 at 07:38
Please share more details, like the code involved. Also, if the gd extension is not enabled, it's obvious that the code won't work — Nico Haase, Aug 08 '23 at 11:40

In the phpinfo output, you are looking at the CREDITS and not at the section that actually reports the extensions that are active.

These are the Credits

And this is the section you would see if the GD extension was active

I would guess that you have more than one php.ini file and the one you are checking/editing to activate the GD extension is not the one your system is actually using.

Look at the TOP SECTION of the phpinfo output, it will tell you which file is being read as PHP.INI
