Ho to get bytesTotal from a dynamic generated content in PHP

http://www.costadelcilento.net/?business-plan-executive-summary-outline Think you want to load from Flash some dynamically generated images from PHP (maybe using GD..), or also some else dynamic content.. Think at this simple code:

creative writing ideas for middle school /**** MovieClip Loader listener ****/ loaderListener = { onLoadStart : function(){ trace('load started!'); trace(" ----------------------------------- ") }, onLoadProgress : function(target, bLoaded, bTotal){ trace(bLoaded + "/" + bTotal) }, onLoadComplete : function(target){ trace(" ----------------------------------- ") trace("complete: " + target.getBytesTotal()); trace(" ----------------------------------- ") } } // I just add the rand variable to prevent caching... movie_path = "http://local/ob_start.php?file=C:/DSCF0182.JPG&rand=" + new Date().getTime() var mcLoader = new MovieClipLoader() mcLoader.loadClip(movie_path, loader) mcLoader.addListener( loaderListener )

Now, if your PHP code is written in this way (just a image copy and resize using the GD 2.x library):

<?php // Get the required image from GET $image = $_GET['file'];$size = getimagesize($image); // create an empty image and copy the original $dst_img = imagecreatetruecolor($size[0]/4, $size[1]/4); $src_img = imagecreatefromjpeg($image); // resize image imagecopyresized($dst_img, $src_img, 0, 0, 0, 0, $size[0]/4, $size[1]/4, $size[0], $size[1]); // start output content header("Content-type: image/jpeg"); // display the image imagejpeg($dst_img, "", 80); ?>

You will be noticed that the http://www.lakecharlesclinicaltrials.com/is-homework-really-necessary/ bytesTotal variable in flash is always ‘0’! follow link This could be a problem if you want to use any kind of graphic preloader for this such of things… However with some little more code it’s always possible to get in flash (and not only from flash) the exact content bytes lenght. Try now this:

click <?php // Turn on output buffering ob_start(); // Get the required image from GET $image = $_GET['file']; $size = getimagesize($image); // create an empty image and copy the original $dst_img = imagecreatetruecolor($size[0]/4, $size[1]/4); $src_img = imagecreatefromjpeg($image); // resize image imagecopyresized($dst_img, $src_img, 0, 0, 0, 0, $size[0]/4, $size[1]/4, $size[0], $size[1]); // start output content header("Content-type: image/jpeg"); // display the image imagejpeg($dst_img, "", 80); // send the content lenght to output header("Content-Length: ". ob_get_length()); // flush the output ob_end_flush(); ?>
