No, it's not a School exercise of some sort but my first php micro project.
The script I sent was a part of php file display.php that is supposed to process a html form showpage.html. Thanks.
Here is Showpage.html
<html>
<head>
</head>
<body>
<?php
//List for storing the parsed lines

//read file

$strCurrentLine = fgets ( $nFileHandle, 4096 );
if (strlen($strCurrentLine) < 7)
{
continue;
}//end if (strlen($strCurrentLine) < 7)
