wamp server php extension PECL Missing

Does any one know why the PECL extension in wamp server does not exists?

I am trying to use the http_build_url() but I get this error:

Fatal error: Call to undefined function http_build_url() in ...

The function http_build_url() is part of the PECL extension pecl_http.

In your WAMP directory locate pecl.exe and open a command shell. Type: pecl install pecl_http and the function call should work.

i have found this source of pecl_http package, but dont know how to make it work on wamp as there is no .dll file in there.

http://pecl.php.net/package/pecl_http

This question is old now, so if you want pecl with wamp 2.2, click on the wamp icon, hover over php->php extensions and make sure that php_http has a checkmark next to it. Doing this enabled pecl for me.

I'm using WAMPServer (x64) with PHP5.6.25 & I want to install "Blesta", the requirements need "Pecl - Mailparse", So:

1. I download "PHP Mailparse v2.1.6 (PHP v5.6)(Thread Safe)(vc11)(x64)"

2. I extract the download file in "C:\wamp64\bin\php\php5.6.25\ext" folder

3. I add "extension=php_mailparse.dll" to file "C:\wamp64\bin\php\php5.6.25\phpForApache.ini" but at the end of "Dynamic Extensions"
4. Restart the WAMPServer
5. Install "Blesta"
