Um PHP mit cURL-Unterstützung nutzen zu können, muss man PHP mit der Option --with-curl[=DIR] kompilieren, wobei DIR das Verzeichnis angibt in dem sich die Bibiotheken und die Includedateien befinden. In dem include Verzeichnis sollte ein Unterverzeichnis namens curl existieren, dass die Dateien easy.h und curl.h enthält. Zudem sollte eine Datei namens libcurl.a in dem lib-Verzeichnis sein. Ab PHP 4.3.0 kann man PHP mit der Option --with-curlwrappers konfigurieren, um cURL für URL-Streams nuzten zu können.
Hinweis: Anmerkung für Win32-Nutzer
Um dieses Modul in einer Windows-Umgebung nutzen zu können, müssen libeay32.dll und ssleay32.dll im PATH verfügbar sein. libcurl.dll von der cURL-Webseite wird nicht benötigt.
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.

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.

You never need to compile at windows (unless you want to play with it). So it's not confusing at all.
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.
If anybody has problems with getting new curl working with older version of php then ...
I got stuck with installing curl-7.10.2+php 4.0.6 or better said configuring PHP with mentioned version of curl.
After some hopeless attempts to configure curl support into PHP I saw an error message:
"checking for cURL greater than or equal to 7.8... ./configure: line 11725: test: 070a02: integer expression expected"
after which configure said: "configure: error: cURL version 7.8 or later is required to compile php with cURL support"
On the mentioned line "test" is used to compare verion from curl-sonfig with preset value 70800 but ... test expects both values to be integer. From verson 7.8 curl outputs its version in hex...
I did'nt had the time to think about fixing this - I just deleted lines responsible and got curl working :)
