Hello,
Does any included file in PHP have a unique identifier? (like a stack of includes identifier).
If the files names are different, then __FILE__ can be used as an identifier. But if a file was included by itself, then __FILE__ is the same, tho there are 2 different includes of the same file.
Example:
=== a.php
<?php
echo "\nRunning ".__FILE__." (id=X)!\t";
if (!$visited) {
echo "You are visiting here!";
$visited = true;
include(__FILE__);
}
else {
echo "You have been already visiting here! (Bye)";
}
?>
-thanks, Eli
