Add a String to a filename

[Anon]

A very stupid question, I'm not using PHP too much, so I'm already in trouble only to add a string to a file name :-(

What I want to do is make a IF statement like this:

if (!file_exists($codice.jpg) {
$codice = "xxxx"; }

In other words it should check for existency of a file name that has .jpg as extension, $codice is a number without .jpg .
I need to have them togheter to check file system and than, if it does not exist, assign the value xxxx to variable $codice.

Could you translate it for me in PHP ?

Many thanks

Fabio

PHP replaces $variables inside of double-quoted strings, so just put quotation marks:

 if (!file_exists("$codice.jpg") { 
                     $codice = "xxxx"; }
