<?php $html = file_get_contents('http://www.google.com/'); // skipped: error checks // split $html lines $lines = explode("\n", $html); // iterate on lines foreach($lines $line) { // process $line } // or 5th line $fifth_line = $lines[4]; // or iterate using index for($line = 0; $line < count($lines); $line++) { $theline = $lines[$line]; } php line-by-line
