Hi phpdotnet,

Try this:

$i = 1;                                     // Start the line counter at 1
$text = $_REQUEST['links'];     //  Get the entire textbox data into $text
foreach( split( "\n", $text ) as $line ) {    // Split the textbox data by carriage return ( \n )
    print "Line " . $i++ . " has $line\n";          // Display the contents of this line
    if( $i >= 10 ) {                    // Stop printing lines once we've reach 10
        last;
    }
}
