    PHP variables to Javascript variables - quick question

    I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.

    I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.

    I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program).

    I found on another thread a means to do this for a date variable:
    Code:
    var jsArray = new Array(
    <?php
    $length = count($monthDataArray);
    for ($i = 0; $i < $length; $i++)
    {
    echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "\n";
    }
    ?>
    but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls.

    I tried:
    Code:
    <script type="text/javascript">
    <!--
    
    var maxxarray = new Array(
    <?php
    $length = count($maximgsarray);
    for ($i = 0; $i < $length; $i++)
    {
    echo '"' . $maximgsarray[$i] . '"' . (($i < $length - 1) ? ',' : '') . "\n";
    }
    ?>
    
    for (i=1; i <= 12; i++) 
     {      
     document.write(maxxarray[i]+"<br>");
     }
    //-->
    </script>
    inside my page at:
    http://www.moonmilk.org/worlds/testflickr.php
    but the routine above does not seem to be working. No output.

    Could some kind soul advise me where I am going wrong? Each array element is a url in the form:
    "http://static.flickr.com/filename.jpg"

    My full page code is:
    Code:
    <html>
    <head>
    <title>PHP flickr images test</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <meta name="keywords" content="hey there">
    
    <script type="text/javascript">
    <!--
    
    var maximgct=8;
    var maximgsarray=new Array(maximgct);
    
    //-->
    </script>
    
    </head>
    <body>
    
    <?php
    require_once("phpFlickr/phpFlickr.php");
    $maximgs = 12;
    // Create new phpFlickr object
    $f = new phpFlickr("fbc2211a8778e91cd26d3de027eac206");
    
    // echo "maximgcount is  $maximgs total";
    echo "<p>photos tagged with \"cloud\" and maximum of $maximgs<br>\n";
    // Search by the single tag "cloud"
    $photos_red = $f->photos_search(array("tags"=>"cloud", "sort"=>"relevance", "per_page"=>$maximgs));
    foreach ($photos_red['photo'] as $photo) {
        // Build image and link tags for each photo
        $val1= "http://www.flickr.com/photos/$photo[owner]/$photo[id]";
        echo "<a href=http://www.flickr.com/photos/$photo[owner]/$photo[id]>";
        $val2= $f->buildPhotoURL($photo, "thumbnail");
        echo "<img border='0' alt='$photo[title]' " . "src=" . $f->buildPhotoURL($photo, "thumbnail") . ">";        
        echo "</a>";
            $i++;
            $maximgsarray[i]=$val1;
            echo "<br>$maximgsarray[i]<br>$val2<br>";
            // If it reaches the 11th photo, insert a line break
            if ($i % 10 == 0) {
                echo "<br>\n";}
    }
    echo "</p>\n";
    ?> 
    
    <script type="text/javascript">
    <!--
    
    var maxxarray = new Array(
    <?php
    $length = count($maximgsarray);
    for ($i = 0; $i < $length; $i++)
    {
    echo '"' . $maximgsarray[$i] . '"' . (($i < $length - 1) ? ',' : '') . "\n";
    }
    ?>
    
    for (i=1; i <= 12; i++) 
     {      
     document.write(maxxarray[i]+"<br>");
     }
    //-->
    </script>
        
    </body>
    </html>
    Many thanks.

    Don't worry....problem resolved:

    A missing "$" sign and missing "'" marks when assigning the variables.
