How do I install cURL on Windows?

Question

I have followed all the instructions here: http://www.tonyspencer.com/2003/10/22/curl-with-php-and-apache-on-windows/

to install & config apache get the PHP5 packages and get the CURL packages.

I run the apache and run a PHP script. no problem. but when I run the php script with curl, it fails.

It returns: **Call to undefined function curl_version() in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\testing.php on line 5**

In which line 5 is a called to curl_init()

I output the php -i to see whether the right path to extension is called. It is correctly set:

extension_dir => C:\PHP\ext => C:\PHP\ext
cURL support => enabled
cURL Information => libcurl/7.16.0 OpenSSL/0.9.8g zlib/1.2.3

I even tried to run curl_version() but still, same kind of error comes up.
It looks like the PHP can't find the CURL extension, but the php.ini (and also php -i) shows that it is set.

any idea? :)

P.S>  System I m running on:
Windows XP
Apache 2.2
PHP 5.2.6
CURL Win32 Generic Binaries: Win32 2000/XP  metalink    7.19.0  binary  SSL enabled     Daniel Stenberg     249 KB

I didn't get this:

Win32 2000/XP   7.19.0  libcurl     SSL enabled     Günter Knauf    1.55 MB
Should I get this one instead?

The reason I need to use CURL is that it is the requirement from my project. So, I can only stick with that. XAMPP... how does it work in Windows? Is there any site that you can recommend? Thanks.

I have tried a lot of things on installing cURL and check everything, but still, I'm stilling circling around the problem and have no idea what's going on.

The Apache server uses the right PHP.ini. and the PHP.ini has the correct extension_dir and extension=php_curl.dll I have no idea why it doesn't work. even I follow every step for setting it up. :(

Answer 1

I'm using XAMPP, in which there are several php.ini files.

You can find the line in the php.ini files: ;extension=php_curl.dll

Please remove ; at the beginning of this line. And you may need to restart apache server.

Answer 2

I recently installed Curl on PHP5 for Windows Vista. I did not enable the CURL library when I initially installed PHP5, so nothing about Curl was showing up in phpinfo() or php.ini.

I installed CURL by re-running the PHP5 installer (php-5.2.8-win32-installer.msi for me) and choosing "Change". Then, I added the CURL component. Restart Apache, and CURL should work. CURL will show up in phpinfo(). Also, here is a sample script you can run to verify it works. It displays an RSS feed from Google:

    <?php
    error_reporting(E_ALL);
    ini_set('display_errors', '1');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,
    'http://news.google.com/news?hl=en&topic=t&output=rss');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $contents = curl_exec ($ch);
    echo $contents;
    curl_close ($ch);
    ?>

Note: Note to Win32 Users In order to enable this module (cURL) on a Windows environment, libeay32.dll and ssleay32.dll must be present in your PATH. You don't need libcurl.dll from the cURL site.

This note solved my problem. Thought of sharing. libeay32.dll & ssleay.dll you will find in your php installation folder.

Answer 4

I solved the problem.

In my apache, I have to specify:

PHPIniDir "C://php" AddType application/x-httpd-php .php

and for php.ini, instead of using the php.ini_recommend, use php.ini_dist to configure my php.ini.

then make sure the php engine has turned on. then it works now. Thanks all.

Answer 5

You're probably mistaking what PHP.ini you need to edit. first, add a PHPinfo(); to a info.php, and run it from your browser.

Write down the PHP ini directory path you see in the variables list now! You will probably notice that it's different from your PHP-CLI ini file.

Enable the extension

You're done :-)

I have tried everything - but nothing helped. After searching for several hours I found this information:

Apache 2.4.18 for some reason does not load php 7.2 curl. I updated my Apache to 2.4.29 and curl loaded instantly

What should I say: I updated Apache and curl was running like charm
