You can use fgets() function to get the line number.

Something like :

$handle = fopen("forms.php", "r");
$found = false;
if ($handle) 
{
    $countline = 0;
    while (($buffer = fgets($handle, 4096)) !== false)
    {
        if (strpos($buffer, "$searchterm") !== false)
        {
            echo "Found on line " . $countline + 1 . "\n";
            $found = true;
        }
        $countline++;
    }
    if (!$found)
        echo "$searchterm not found\n";
    fclose($handle);
}

If you still want to use file_get_contents(), then do something like :

$homepage = file_get_contents("forms.php");
$exploded_page = explode("\n", $homepage);
$found = false;

for ($i = 0; $i < sizeof($exploded_page); ++$i)
{
    if (strpos($buffer, "$searchterm") !== false)
    {
        echo "Found on line " . $countline + 1 . "\n";
        $found = true;
    }
}
if (!$found)
    echo "$searchterm not found\n";
