I have a simple test code:

<?php
var_dump(curl_init());
echo '.';

if I run it on command line (Windows 10) I get the expected result:

php.exe test.php

resource(4) of type (curl) .

very fine. But when Im running this file from browser (set to Apache rootdir).

Fatal error: Uncaught Error: Call to undefined function curl_init() in

Im speachless. For legacy reasons, this is php 7.04 (on 7.2, 7.4, 8.1 everything is fine). The php.ini does work. Of course "extension=php_curl.dll" is enabled. When I change something, for example "max_execution_time = 300", the php_info(); also reinforcements me that these settings are taken into account. However, the strange thing is what php_info() is saying:

cURL Sterling Hughes

nothing more for curl!

EDIT:

I tried the same with "extension=php_gd2.dll" and it does work if I remove/readd it, phpinfo shows that correctly!

CodePudding user response：

This is because the php folder is not in your system PATH (not user), Apache doesn't know where to search dlls. The easiest way is adding php folder to PATH.

If you doesn't want to do that, you probably need set extension_dir to the full path of your extension folder in php.ini. for example:

extension_dir = "D:\Program Files\php-7.04-ts\ext"

cURL extension needs openssl to work. and you can also find these dlls in php folder, just copy them to Windows or system32 folder. According to RiggsFolly's comment you can copy these required dlls to Apache\bin folder.

• libssl-1_1-x64.dll / libeay32.dll
• libcrypto-1_1-x64.dll / ssleay32.dll
• libssh2.dll
