concatenating strings in php, why doesn't this work?

[GeX]

<?
    $dir = "img/whittingham";

    if (is_dir($dir)) {
        $fd = @opendir($dir);

        if($fd) {
            while (($part = @readdir($fd)) == true) {
                if ($part != "." && $part != "..") {
                    $file_array[] = $part;
                }
            }
        }
    }


for ($x=0; $x < sizeof($file_array); $x++) {
      echo "<img src=\"". $dir."/".$file_array[$x] ."\"><br />";

}
?>

right.. that does what it is supposed to, scans the dir and outputs all the images. now suppose i want to add an alt elemenent to the img tag, surely it would be

."alt="moo""

meaning the output line is;

echo "<img src=\"". $dir."/".$file_array[$x] .alt"moo""."\"><br />";

but if i do that, i get a parser error. i'm a newbie at php, and i can't see where i'm going wrong here.

that makes sense, thanks.

and i agree - much clearer using single quotes!

thanks for the help guys, so many different ways of doing the same thing eh. i'll modify the script to use foreach instead, and pick my new favourite way of making strings
