Running PHP by command line on WAMP

There are a few simple steps one can follow to run php scripts by command line. Usually if you write "php" on the DOS prompt it will not recognize the command. In order to run php on command line in windows you have to do the following - Step 1 : Go to your wamp directory:\wamp\bin\php\php5.x.x (directory depends on your version).

This is the url of the page you are requesting. 4.After url I have the next parameter is left as '' . This parameter is just for adding the parameters (query strings) to the url. It is left to the programmer that he wants to use this parameter or not . You can club your query string in the Url also. 5.Finally we have a ...
