Kurulum

PHP'nin cURL desteğini kullanmak için PHP'yi --with-curl[=DiZiN] seçeneği ile yapılandırarak derlemelisiniz. Buradaki DiZiN lib ve include dizinlerini içeren dizindir. include dizini altında easy.h ve curl.h dosyalarını içeren bir curl dizini bulunmalıdır. Ayrıca, lib dizininde bir libcurl.a dosyası bulunmalıdır. PHP 4.3.0'dan itibaren PHP'yi URL akımları için cURL'u kullanmak üzere yapılandırmak için --with-curlwrappers derleme seçeneğini kullanabilirsiniz. PHP 5.5.0'da nu özellik PECL'ye taşındı.

Bilginize: Win32 Kullanıcılarının dikkatine
Bu eklentiyi Windows ortamında etkin kılmak için libeay32.dll, ssleay32.dll, libssh2.dll ve OpenSSL 1.1'deki gibi libcrypto-*.dll ve libssl-*.dll dosyalarına PATH ortam değişkeni üzerinden erişilebilmek gerekir. cURL sitesindeki libcurl.dll dosyasına ihtiyacınız olmayacaktır.

Upgrading to php 5.6.9 on Windows 7 x64 curl no longer is recognised. No errors on server start package just not available and didn't show in phpinfo.php. deplister.exe was ok
I fixed coping the following list files from php folder (in my case D:\xampp\php)
libeay32.dll
libssh2.dll
ssleay32.dll
to c:\xampp\apache\bin (or your apache\bin path), restart apache and works fine, apache's libraries were outdated

Ubuntu 11.04

I already had Apache and PHP5 setup, but simply adding php5-curl and curl did *not* work. I also had to get libcurl3 and libcurl3-dev. The full command:

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

You'll know if it works because phpinfo() will get a new section with Curl info.

It is not necessary to always (re)compile PHP. For me it was sufficient to install php5-curl and restart Apache:

$ sudo apt-get install php5-curl
$ sudo /etc/init.d/apache2 restart

You may be confused, as I was, by the instructions for installing cURL in php.  The instruction "To use PHP's cURL support you must also compile PHP --with-curl[=DIR]..." was murky to me, since I didn't compile php when I installed it.  I just copied all of the necessary files to the correct folders as described very clearly in the php manual.

I am using Windows XP and Apache with php 5.1.6. In this situation, and it may apply to php versions of 5.0 and later, all one needs to do is remove the ";" from the front of the directive extension=php_curl.dll.  You should also check to make certain that libeay32.dll and ssleay32.dll are in your php directory with the other dll's.  This directory should already be in you path, so the instruction to put them in you path is not critical.

You can then run phpinfo() and you should see a heading for curl in the listing.

Succinctly, my installation of cURL consisted of removing the semi-colon in front of the ;extension=php_curl.dll line in php.ini, saving php.ini and restarting Apache.  You may wish to try this if you are using php 5.0 and later and are having difficulty understanding the instructions on the cURL installation page at php.net

You might also find the information at http://curl.phptrack.com/forum/viewtopic.php?t=52 useful.

Beginning with version 1.1.0 OpenSSL did change their libary names!
libeay32.dll is now libcrypto-*.dll (e.g. libcrypto-1_1-x64.dll for OpenSSL 1.1.x on 64bit windows)
ssleay32.dll is now libssl-*.dll (e.g. libssl-1_1-x64.dll for OpenSSL 1.1.x on 64bit windows)

If you're dense like I am, spare yourself the trouble on an Ubuntu system (probably Debian too) and...

$ sudo apt-get install php5-curl

Then feel dumb, but not as dumb as me.

Win10 64bit, php7 x64,apache x64
It's important to set " extension_dir = "X:/WAMP/php/ext" " clearly in php.ini .
Remember some names of dll has changed recently, specially in the  x64 environment.

You dont need to copy files to use PHP CURL with Apache 2.4 - use the LoadFile directive in your apache config file instead:
LoadFile "C:/php7/libssh2.dll"
(that was all it took for me to get it work)

For those who may be having WordPress issues relating to curl, the answer for me was that the curl.cainfo wasn't specified in the config.  This resulted in a plugin giving some non-graceful errors for which I was finally able to track it down.

curl.cainfo = "C:\php\extras\ssl\cacert.pem"

You'll need a copy of the cacert.pem (doesn't come with PHP and does need to be updated every so often can be found at an official permalink of:
https://curl.haxx.se/ca/cacert.pem

They use a modified version of Mozilla's certificate store meant to work with libcurl.

I'm not an expert, this is just what fixed the errors for me.

(cacert.pem lists official root certificate providers so your computer knows which ones its safe to authenticate against is my lay interpretation.  I'm sure it's not technically accurate but close enough for us lay people.)

If you are running on Windows with a Wampserver or alike preconfigured PHP, if you did everything that was advised (path is correct, dlls are in the System32 or the Wow64 folder, php_curl extension uncommented in the php.ini, rebooted your machine and restarted your services), and you still receive messages saying that curl is not installed :
- maybe you are running a command line script (and not a curl instruction within a web application). If yes, remember that there are 2 distinct php.ini configuration files : one for the php-cli commands (run php at command line) and one for the php instructions (run from a page in your www folder).
Wampserver's menuitem "php.ini" only opens the webserver's php.ini, not the php-cli one.
So it will be great to check your php-cli's php.ini configuration file ! (you'll find it in the php.exe's installation folder)
You need to uncomment the extension php_curl in this php.ini file for the command lines to work with curl.
Also uncomment the php_openssl extention by the way (often used with curl).
I hope this fixed issue will help someone else :)

Just an additional note for Windows XP installations ...

The instructions others have courteously given still lack one small item for those who have the Windows/system32 directory as the repository for the .dll files concerned with php_curl.

Go to the ext directory of your php installation and copy php_curl.dll  to the Windows/system32 folder after you have followed the advise given elsewhere.

So ...
1) remove ';' from extension=php_curl.dll in php.ini
2) ensure that  ssleay32.dll and libeay32.dll are in Windows/system32.
3) Copy php_curl.dll into Windows\System32 as well.

G'day

In my case, while running Windows 10 and Apache Httpd 2.4, I had to add my PHP7 root directory to Windows PATH and it resolved issues with failing to load couple of PHP extensions.

Upgrading to php 7.1.6 on Apache 2.4 32bit version Windows 7 x64

this curl  implementation works:

1.   C:/(path to php folder)/php.ini
enable extension=php_curl.dll

libeay32.dll, ssleay32.dll, libssh2.dll find directly in php7 folder

2. add this to Apache/conf/httpd.conf
# load curl and open ssl libraries
LoadFile "C:/(path to php folder)/libeay32.dll"
LoadFile "C:/(path to php folder)/ssleay32.dll"
LoadFile "C:/(path to php folder)/libssh2.dll"

For Windows 7 (64 bit), ensure you not only enable the curl extension (i.e. uncomment "extension=php_curl.dll" in php.ini) as described in this manual, but also set the extension directory for Windows (e.g. extension_dir = "ext") in the php.ini file.  Adding / copying dll files or changing the system path were not necessary.  (Versions used: Apache 2.4.1 (Win64) and PHP 5.5.15.)

if you cant solve this "Fatal error: Uncaught Error: Call to undefined function curl_init()" on WINDOWS

Try add to this strings to apache config (httpd.conf):

LoadFile "C:\Program Files\Apache\php\libssh2.dll"
LoadFile "C:\Program Files\Apache\php\libcrypto-1_1-x64.dll"
LoadFile "C:\Program Files\Apache\php\libssl-1_1-x64.dll"

and restart apache (dont forget to use your php folder name);

Moving this files to apache or windows folder, dont work for me:

libeay32.dll (libcrypto-*.dll)
libssh2.dll
ssleay32.dll (libssl-*.dll)

I had curl not working in Windows with Apache 2.4 and PHP 7.3 - Strangly phpinfo showed author but not curl section/panel.

I changed the widows path to include the PHP directory and after a reboot it started working.

You can change the windows path in Control Panel -> System -> Advanced System Settings -> Advanced -> Environment Variables  then edit the path variable in "System Variables"
