Variables...

[xphp]

Hello,

I have a forum that uses the GET function to get text file data from the directory. EG (One types in JOE and then the form uses the fopen cmd to open that text file) The problem is that I dont know how to use variables to convert Joe into JOE.TXT when the user enters it.

Help PLEASE!

Is this homework? Note you're looking at a security problem if you just open any file the user names. You should have a list of allowed names and use in_array() to check the input is AOK. The other functions at php.net to lookup at http://www.php.net/manual/en/ are these:

strtoupper()
readfile()
and this string operator:

Forget fopen() unless this is an assignment.

Ohh no I just used that as an example, it will be used as a search function type thing
