[FX.php List] PHP and Javascript?

[Michael Layne]

Chuck,

Well, here's how I populate a JavaScript array with a PHP one... 
grabbing photos that live in the file system and belong to a particular 
record ($record)

<script type="text/javascript" language="javascript">
<?
$maindir = $_SERVER['DOCUMENT_ROOT']."/" . $site . "/photos/";
$mydir = opendir($maindir) ;
$c = 0;
while($fn = readdir($mydir)) {
    if ($fn!= "." && $fn!= ".." && substr($fn, 0, 5) == $record) {  
//this condition can be anything or nothing.  It's specific to my app...
    echo "Pic[" . substr($c,0,2) . "] = '../photos/" . $fn . "';\n"; // 
here's where the JavaScript array gets outputted.
    $c++;
    }
}
closedir($mydir);
?>
</script>

HTH.  Let me know If I can (try) to explain anything more...
