deletes files from pHP

<?php 
file1 = "image.jpg";
$startdate = mktime(0,0,0,12,17,2003); //mktime(hour, minute, second, month, day, year) 
$datetoday = mktime(date("h, i, s, m, d, Y"));//todays date 
$datediff = $datetoday - $startdate; 
$numdays = round($dateDiff/60/60/24, 2); 
$equalday = '$numdays == 7';
unlink '$file1';
echo 'There is about ' . $numdays . ' days left to download.<br />';
echo "Files has removed!";
?> 

This scripts will set a time when it will delete the file.
For example, when it's about 7 days, it will delete the file "$file1", could any one re-write this PHP to makes it works?

It's like a weekly pictures, by the 7 days it will delete it self and said "times is up"

You need to test if the number of days is 7 or greater. You have this: $equalday = '$numdays == 7'; but this doesn't make much sense (the value of $equalday is '$numdays == 7' which is a string).

I think you want:

if($numdays >= 7)
{
  // code to delete file goes here...
}  // end if($numdays >= 7)

<?php 
$file1 = "image.jpg";
$startdate = mktime(0,0,0,1,4,2003); //mktime(hour, minute, second, month, day, year) 
$datetoday = mktime(date("h, i, s, m, d, Y"));//todays date 
$datediff = $datetoday - $startdate; 
$numdays = round($dateDiff/60/60/24, 2); 
if($numdays >= 7) 
{
unlink '$file1';
}
echo 'There is about ' . $numdays . ' days left to download.<br />';
echo "Files has removed!";

Seem nothing is working.. i don't see the echo either..
