Follow-up from my post yesterday (Enabling cURL with PHP)
The problem is that PHP isn't able to load php_curl.dll. I've tried several steps including uncommenting extension=php_curl.dll, making sure the dependencies libeay32.dll and ssleay32.dll eixst in the path, re-downloading php_curl.dll, replacing the old one, and lastly copying the file into my System32 folder.
I'm using Apache 2.2 and PHP 5.4.14. I installed both using their individual packages; I'm not using XAMP or WAMP. I'm using Windows 7 64-bit.
Any help at all would be appreciated.
Solution: Put libeay32.dll, libssh2.dll, ssleay32.dll files under dir specified in httpd.conf's ServerRoot directive. These dlls can be found compiled under php root folder.
Reasons:
Problem is php_curl.dll requires to access following libraries while loading: libeay32.dll, libssh2.dll, ssleay32.dll and it does not make sense if you put them in ./php/ext dir or if you put php extensions in php root dir.
Of course you can put them in c:\Windows or in some global folder defined in PATH but if you dont want to do this and you want that your apache+php installation was portable:
The path specified in ServerRoot in httpd.conf is treated as home path for php. The behaviour is similar to situation where you include ./path/to/some.php file in ./index.php and home path for some.php file is still ./ the dir where index.php resides.
In shorts just put those three dlls right in dir you specified in httpd.conf ServerRoot directive and php_curl.dll will not fail to load again.
Make sure to have your apache SSH dlls loading correctly. On a fresh install I had to download and load into my apache bin directory the following dll "libssh2.dll"
After ssl dll was loaded cURL was able to load with no issues.
You can download it from the link below:
Add your php folder path to the System PATH and everything should work fine. It will also fix some other extensions that are broken.
You are loading .dll so your OS has to be windows.
First check which php.ini file you are using by running phpinfo()
Then check where your extensions folder is by checking extension_dir attribute in that file.
Next make sure that php_curl.dll is present in that folder. If not copy it over.
Restart apache and check if it works.
Since you installed packages individually, also do this:
Copy the dll file from php_installation_folder/extensions to apache_installation_folder/bin
I have encountered the same problem before.I resolved it by add php directory to windows system environment variables---Path.
Usually this is an OpenSSL version mismatch error, between Apache and PHP. In case Apache loads PHP as a DSO module, its own OpenSSL versions (dlls and libs) will be used. So, in case the PHP extension requires a newer version, it may not find the appropriate interface inside the Apache-loaded DLLS and it will fail to work.
Since you need the PHP extension to load, you need the relevant DLL files to be at least the version of what the PHP module asks for. Supposing that you 're using lastest builds for both Apache and PHP and both having been built with the same MVC version, you can copy the following files:
from the PHP root folder to the Apache2/bin folder, in case you 're confident that the PHP build is newer than the Apache build.
In the opposite case, you can copy the same files from the Apache BIN to the PHP root.
In any case, backup the contents of the APache and PHP folders beforehand.
Adding the PHP path as an enviromental variable will give priority to this path for loading the relevant DLLs and may solve the problem. However, you lose in server portability. Additionally, if you have also added the Apache PATH as a variable and the OpenSSL versions are way different (up to loading different linked DLL files), a lot of shit may happen.
In php.ini you must put the extension_dir static path. extension_dir = "C:\laragon\bin\php\php-7.3.11-Win32-VC15-x64\ext" by example. Don't forget to remove the semicolon before this variable.
In PHP 5.6.x version You should do the following:
Move to Windows\system32 folder DLLs from php folder:
libssh2.dll, ssleay32.dll, libeay32.dll and php_curl.dll from php ext folder
Move to Apache24\bin folder from php folder:
libssh2.dll
Also, don't forget to uncomment extension=php_curl.dll in php.ini
Insert to file httpd.conf
LoadFile "D:/DevKit/PHP7.1/libeay32.dll"
LoadFile "D:/DevKit/PHP7.1/libssh2.dll"
LoadFile "D:/DevKit/PHP7.1/ssleay32.dll"
After having tried everything here I had to simply upgrade Apache to a newer version in order to make curl extension work.
I was upgrading PHP from 7.0.2 to 7.1.15 after which curl did not work. Only way to fix it was upgrade Apache (which was version 2.4.18) to the latest 2.4.29.
Didn't have to copy any of the lib/ssleay dll files to either Apache or Windows - possibly because I already have the PHP folder in my system path.
Running Windows 10, 64-bit, thread-safe versions, VC14.
I got this error because, on my system at least, if extension_dir in php.ini is set to a relative path, it is taken as being relative to the root Apache directory, so to get it to point to the correct directory I had to use an absolute path: "C:\Program Files (x86)\PHP\ext". (This was PHP 5.5.31 and Apache 2.4.23 on Windows 10; setting extension_dir to ext worked just fine with the same setup on Windows 7. I first got it to work by putting an ext directory in the Apache folder with the necessary dlls, then figured out what was happening.)
It was also necessary to set the PATH correctly or make sure the dlls mentioned above (libeay32.dll, libssh2.dll, and ssleay32.dll) are in Apache's bin directory (or most likely any of the places other answers mention). The fact that I got the same error message for Apache not being able to find lib_curl.dll as for it not being able to find libssh2.dll did not make things any easier to figure out.
Solution:
Step1: Uncomment the php_curl.dll from php.ini
Step2: Copy the following three files from php installed directory.i.e "C:\\php7".
libeay32.dll,
libssh2.dll,
ssleay32.dll
Step3: Paste the files under two place
httpd.conf's ServerRoot directive. i.e "C\Apache24"
apache bin directory. i.e "C\Apache24\bin"
Step4: Restart apache.
That's all. I solve the problem by this way.Hope it might work for you.
