I like to get a dir listing in php
glob("*.jpg"); or
$dir = '.'; //requested directory to read $notthat = array('.', '..'); //what not to include $listedfiles = array_diff(scandir($dir), $notthat); // removed what not to include so i like to send that array to a javascript like that (slides = $listedfiles)
function startSlideshow(slides) { .. do something..} What is the best way to do that ?
json_encode is your friend for this. No looping is necessary. It will return a pure json object string that you can then just echo into your js file using PHP. Example:
var slides = <?php echo json_encode( $filelistarray );?> function startSlideshow(slides) { .. do something..} you can always just do an echo of it to a javascript :
echo ' <script type="text/javascript"> var filelist = []; '; foreach($listedfiles as $file) { echo " filelist[] = $file; "; } echo "</script>"; PHP and Javascript cannot directly interact, however, you can output Javascript from PHP the same way you can output plain text or HTML:
<script type="text/javascript"> var slides = []; <?php foreach ($listedfiles as $file) { echo "slides[] = '" . addslashes($file) . "';\n"; } ?> // ... do js stuff </script> Basically, after creating your array in PHP, you output the JS code to create the same array in javascript.
