You can search each line with stripos

<?php

$handle = fopen('javascriptfile.js', 'r');
$match = 'url.instance = "www.google.fr";';

if ($handle) {

    while (!feof($handle)) {
        $buffer = fgets($handle);

        // check each line start with : url.instance = "www.google.fr";
        if (stripos($buffer, $match) === 0 ) {
            echo "<input type='text' value='$buffer'>";
        }
    }

    fclose($handle);
}
