[PHP] file_get_contents?

I am trying to use the file_get_contents to check a variable in a different document however it's not checking the document (index.php) and then echo the result.

Show Hide

PHP Code:

---

<?php 
$license = file_get_contents("index.php");
$license = "Copyright 2007, all rights reserved.";
if ($license == FALSE){
 echo"You cannot remove the copyright disclaimer!";
}
else 
{
}
?>

I dont see how that code would work...

PHP Code:

---

<?php 
$source = file_get_contents("index.php");
if (eregi('Copyright 2007, all rights reserved',  $source)) {
print("Copyright present");
}
else{
print("Copyright not present");
}
?>

Try that

Works great, thanks Danny.

Is there anyway that it if the copyright is present that it will do nothing if not it will die and echo "Copyright not present"?

PHP Code:

---

<?php 
$source = file_get_contents("index.php");
if (!eregi('Copyright 2007, all rights reserved',  $source)) {
exit("Copyright not present");
}
?>

Many thanks again Danny.
