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)
要 PHP 支持 cURL，必须在编译 PHP 时加上 --with-curl[=DIR] 选项，DIR 为包含 lib 和 include 的目录路径。在 include 目录中必须有一个名为curl，包含了easy.h 和curl.h 的文件夹。lib文件夹里应该有一个名为libcurl.a的文件。对于 PHP 4.3.0 你可以配置 --with-curlwrappers 使 cURL 使用 URL 流。
Note: Win32 用户注意
要在 Windows 环境下使用这个模块，libeay32.dll 和 ssleay32.dll 必须放到 PATH 环境变量包含的目录下。 不用 cURL 网站上的libcurl.dll。

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)
Found an issue with getting curl extension to work with PHP7 on Windows Server 2016 (same on Windows 10) running Apache 2.4.x.
I had uncommented the extension (php_curl.dll) but it still would not show in phpinfo(). I found the answer in the comments but given they were written for PHP 5.3.4 and not correct for PHP 7.1.x I thought I would update the steps to getting curl extension to work after uncommenting in php.ini file.
You need to copy the following three files from your PHP7 folder (e.g. C:\PHP7)
libeay32.dll
libssh2.dll
ssleay32.dll
and paste the copies into your Apache/bin folder (e.g. C:\Apache24\bin)
Then restart Apache2 service and load phpinfo() again to see curl extension showing. You should be good to go and hopefully avoid the hours I lost trying to find a way to get curl to load.
For Ubuntu and probably debian:
apt install php-curl
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.
At least for windows builds of PHP, module dependencies (such as "libeay32.dll", "libssh2.dll", "ssleay32.dll", etc. for php_curl) are mentioned in "snapshot.txt" included in the base folder of each PHP install.
For WampServer (I'm on an old version of 2.0 but this still applies at least up to version 2.5), ensure that all dependencies are listed in an array assigned to "$phpDllToCopy" in "Wamp\scripts\config.inc.php". This ensures that when you switch the version of PHP in WAMP, WAMP copies the dependencies from the base folder of the selected PHP install (e.g., "Wamp\bin\php\php5.4.42") to the "bin" folder of the currently selected version of Apache (e.g., "Wamp\bin\apache\apache2.2.13\bin").
This also keeps you from either manually doing the same (whereby it should be noted that the versions of the dependencies often differ between versions of PHP, so you may have to do this each time you switch the current version of PHP), copying the appropriate dependencies to the Windows "System32" or "SysWOW64" subfolders, or manually adding the path to the currently used version of PHP to your PATH environment variable.
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.)
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
Win32 Users: As of PHP 5.5 you also have to libssh2.dll on your path along with libeay32.dll and ssleay32.dll for cURL to work.
I had to also also copy libssh2.dll into my Apache24 folder for this to work with my PHP 5.6.2 installation. So altogether I had to do the following:
Move to Windows\system32 folder:
libssh2.dll, php_curl.dll, ssleay32.dll, libeay32.dll
Move to Apache24\bin folder
libssh2.dll
Uncomment extension=php_curl.dll
On Windows hosts libeay32.dll and ssleay32.dll have to be path-accessible for php_curl.dll to work correctly. Copying them into System32 (or even into the Windows main directory) is a bad hack (and does not even work with newer PHP versions). The right way to do it, is to add the PHP path to the Windows *Path* variable. In *Control Panel* --> *System* click on *Advanced System Settings* and use the button *Environment Variables*. Under *System Variables* you will find the *Path* variable. Edit it and append `;C:/PHP` to it - or whatever the path to your PHP root folder is.
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
make sure there is a curl-config under DIR or DIR/bin
otherwise there will be an error when running ./configure
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 :)
A tip for users that now use the latest version of Windows 7 Ultimate, Apache 2.2.22 and PHP 5.4.4. If you manually installed PHP and did not change the PHP folder name such as "C:\php-5.4.4-Win32-VC9-x86" you don't need to add the curl libs into the System32 directory. Instead, modify the php.ini cURL extension to point directly to the php_curl.dll as follows:
extension=C:\php-5.4.4-Win32-VC9-x86\ext\php_curl.dll
I added the libs to system32 and moded the path as well just in case. Worked well for me.
It should be noted that on a standard installation of php 5.2.17 on windows has this functionality installed and enabled by default.
For users of win7 64:
I just copied the library php_curl.dll to System32 and it works like charm ;-)
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.
For Windows 64, put the DLLs into the Windows/SysWOW64 Folder.
It's not sufficient to put libeay32.dll and ssleay32.dll into your path. They also need to be in the PHP directory or it will not function, apparently.
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

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.
Tip for Installing cURL with AppServ development server on Windows
If you are running AppServ as a WAMP development environment on a Windows machine, you may experience difficulty installing cURL. Here are some helpful steps:
First go to the PHP directory and copy the following libraries to the windows/system32 dir.
ssleay32.dll
libeay32.dll
Open the php ini file and remove the ; from extension=php_curl.dll
Reboot your machine to load [...]
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.
If you are using WAMPserver, you can enable the cURL extensions by
Left-click on WAMPserver tray icon>PHP>PHP extensions> Check php_curl.
Its already loaded on your disk, you have to activate it.
If you are using XAMPP (http://www.apachefriends.org/en/index.html) all you have to do is uncomment this line (line 582):
extension=php_curl.dll
in the xampp\apache\bin\php.ini file.
