[Include in for-loop]

Hello,

I have some php-files containing variables with same names but different data.

$arr = array("file1.php", "file2.php", "file3.php");

I want to "get access" to these variables/data. One php-file at a time. This is what i am doing right now:

for($i=0; $i<sizeof($arr); $i++)
    include $arr[$i];

This does work in the first 2 php-files in the array but not on any other of them unless i change start-value of $i. Could you maybe help me solve this?
