WampServer

I've recently installed the PHP 7.1.17 add-on to my existing WAMP installation. However after selecting PHP 7.1.17 as the running version cUrl no longer seems to work. However cUrl still works when I select previous any of the versions (7.0.0 or 5.6.16).

The PHP error log says:
PHP Warning: PHP Startup: Unable to load dynamic library 'C:/wamp64/bin/php/php7.1.17/ext/php_curl.dll' - Kan opgegeven procedure niet vinden. in Unknown on line 0

The php_curl.dll file exists in the 'C:/wamp64/bin/php/php7.1.17/ext/' path. In the PHP.INI file and the phpForApache.ino file the "extension=php_com_dotnet.dll" line is uncommended (no semicolon). However when I create a php file and view phpinfo() cUrl does not show.

Please advice.

I'am running Windows 10 (x64) with WAMP 3.1.3 (x64) with Apache 2.4.17. The WAMP icon is GREEN.

Hi,

Use at least Apache 2.4.23.
But, for recent PHP versions, it is best to always use the latest version of Apache : 2.4.33

As far as I am aware the `php_com_dotnet` extension has nothing to do with the `php_curl` extension so why did you mention that?

@RiggsFolly, you are right. I copied and pasted the wrong line. I ment "extension=php_curl.dll". (Double checked it just now).

@Otomatic, I installed the Apache : 2.4.33 update for WAMP and rebooted my PC. Unfortunately still the same problem with cURL.

Any other suggestions I could do or check?

Hi,

> I installed the Apache : 2.4.33 update for WAMP
You need to switch to Apache 2.4.33 in place of Apache 2.4.17.

Left-Click Wampmanager tray icon -> Apache -> Version -> 2.4.33 (Click on 2.4.33)

@Otomatic, yes I did also switch the Apache version in WAMP. But with both Apache versions I still get the Curl error. Strangely when I switch back to PHP version 7.0.0 cUrl works fine. But on PHP version 7.1.17 it doenst work

Hi,

- Verify that all VC ++ packages are installed and with the latest versions.
To do this, use the tool:
Checks VC++ packages installed
And you will find all the packages on [wampserver.aviatechno.net] in section Visual C++ Redistribuable Packages
Do not forget that if you have a 64 bit Windows, you must install both 32 and 64 bit versions of each package.
You must install each package "as an administrator", so right-click the exe file and then run as Administrator.
Do not use a previously loaded tool. Make a new download to make sure you are using the correct version.

I didn't want to open a new thread since this seems to be the exact same problem I'm having, but I'm not sure how to resolve it after many hours of trying everything I could dig up here and on SO.

I'm on Windows 10, upgraded my 2.5 installation using wampserver2.5_x64_update_3.0.3.exe, then wampserver3_x86_x64_update3.1.9.exe to get to 3.1.9.

Curl works fine with PHP 7.03 (and below); but I need a higher version for a project, and it fails with 7.1.32, 7.2.23 and 7.3.10. Same problem as the OP, error log says:

PHP Warning: PHP Startup: Unable to load dynamic library 'curl' (tried: C:/wamp/bin/php/php7.3.10/ext/curl (The specified module could not be found.), C:/wamp/bin/php/php7.3.10/ext/php_curl.dll (The specified module could not be found.)) in Unknown on line 0

I'm using Apache version 2.4.9, and yes all the VC packages were installed/verified before the updates. Is there any chance this is related to the update instead of clean installation? I have no idea if this was resolved for the poster.

Any thoughts much appreciated!

Thanks.

I m facing the same issue, any help would be much appreciated.

Hi,

Apache 2.4.9 seems to be not compatible with PHP 7.3

I upgraded to apache 2.4.41 from 2.4.35 and seems to have fixed the issue

I can confirm: I was getting same curl extension error on php7.2.34 and php7.4.13, while on php7.0.8 it worked fine.
Updated my apache2.4.20 to 2.4.46. It was a bit hard since I couldnt find a ready-made apache; had to install newer wamp to a different folder, but it overrode my apache and mysql services, had to revert it back. Also had to change
Define VERSION_APACHE 2.4.46
Define INSTALL_DIR "C:/wamp64/"
since my older wamp3.0.0 probably had no idea about that.

And now with apache2.4.46 newer versions of php work fine, no php_curl.dll error on exactly same php7.2.34 folder.
Just update your apache.

Hi,

For Wampserver, there are ALWAYS two places to look:
- WAMPserver 3 - All you need to know
- https://wampserver.aviatechno.net/

There was no need to install another version in another place, just keep up to date! There is a cumulative update for Wampserver, 3.2.4 today. Your version 3.0.0 was old enough to go to school, in the Preparatory Course.
