Fatal error: Call to undefined function socket_create() for WAMPServer

Here's a solution I found upon experiencing an error in WAMP

Scenario

I am using WAMP (wampserver) and trying to run a chat service program via HTML 5 with the use of websockets.



I did enable my php_sockets via WAMP interface.

wamp > PHP > PHP Extensions > php_sockets

Upon trying, I received an error from the command prompt saying:

Fatal error: Call to undefined function socket_create() in [FILE] on line [LINE OF CODE]

Solution

It seems that the command prompt was using a different configuration file for PHP.

Apache (or from the WAMP's interface) uses a php.ini that is located at:

[WAMP_DIRECTORY]\bin\apache\Apache2.2.21\bin\php.ini

If you will open this file, you may notice that the line extension=php_sockets.dll is already commented out.

Unfortunately, the CLI or command line interface is using a different configuration file which is located at:

[WAMP_DIRECTORY]\bin\php\php5.3.8\php.ini

In order to resolve it, you should comment out the line extension=php_sockets.dll and save it. Run the program after to see if the websockets again are already up and working.
