Function http_build_url ()

Question

I am working with Windows 7 using WampServer Version 2.2 php5.3.13

I put my project in www

and during the execution of my project this error is displayed

Fatal error: Call to undefined function http_build_url() in C:\wamp\www 

I use this syntax in the source code of my project

 $url = http_build_url($url); 

I think I need to configure wamp

Answer 1

• Check the extensions folder for the php_http.dll file.
• If the file is present, check that the php_http extension php_http included in your php.ini (or any other .ini-s included)
• If the file is missing, either download it separately from http://downloads.php.net/pierre/ , or download along with other extension extensions (you may need several of them) from http://museum.php.net/php5/ pecl-5.2.6-Win32.zip . Configure php.ini to enable the extension.
• Reboot the web server.
