It is a way better practice if we use do not use register_globals. If you try to avoid this error you will have to go through lots of change. though you are beginner which mean you are learning. I would suggest you to remove the line from your php code. now what does it do: Say you have a from with two input field name and age. when you submit and if your register_globals function is called your php will create two variable name: $name, $age and will set the value from the form field. example: <form method="get"> <input name="name"> <input name="age"> <input type="submit"> </input></input></input></form> you will also get a variable name $submit now what's wrong with this: a request can come in two way : 1. POST Method 2. GET Method in both case register_globals will create variabls. but you would never know how it came. is this a problem? in cases it is. but read more you will get more problem Register_globals also register $_SESSION, $_COOKIE, $_HEADER, $_ENV So perhaps your data will easily be overlapped with other data. Actually one data will be lost. what would you use instead of register_globals? $_GET for get method $_POST for post method $_SESSION for session data; it also has other related function $_COOKIE for cookie data; it also has other related function $_HEADER for header data $_ENV for environment related data This article describes how to enable and disable the register_globals directive in a custom php.ini file.
