How to work with if

[fri]

Hi, I am trying to make the if statement work but was unsuccessful. All I want to do is display something based on the change of the URL.

For example, like this if statement:

<? if (file_exists($whateverfile)) { ?>somethingshown<? } ?>

something can be shown if that $whateverfile exists right? Well I am a noob at php and would want to show something based on if there is an ID number? can anyone PLEASE help? Thank you so much.

 <? if (file_exists($whateverfile)) { ?>somethingshown<? } ?> 

Try this..

 <?php
if (file_exists($whateverfile)) { 
echo "The file is " . $whateverfile . ".";
}
else {
echo "The file doesn't exist.."; }
?>

Remember.. $whateverfile needs to have a variable so like.. add
$whateverfile = "Yo sup homeslica G";
or something..
