I am trying to get the image width from the url of the image. Is that possible ??
What i am trying to do is, if a user uploads image from the editor and if the width of image uploaded is greater than 700px then i will resize the image and use that in place of the original one. I am grabbing all the images in the editor like this

$doc = new DOMDocument();
$doc->loadHTML($this->PageAdvancedPopup_html);
$imageTags = $doc->getElementsByTagName('img');
foreach($imageTags as $tag) {
$imgs = $tag->getAttribute('src');
echo "<img src='/$imgs' />";
}

Now how can i check the width of these image ??
Please help me I am stuck...

Hi Sultan,
You wont be able to do it via the URL. You'll need to actually load the image first to read that property. Unless of course you control the HTML you could output it in the <img> tag.

To do this yourself first load the image with imagecreatefromjpeg http://php.net/manual/en/function.imagecreatefromjpeg.php
then read width with getimagesize http://www.php.net/manual/en/function.getimagesize.php
It'll be the first item in the array of getimagesize.

Eg.

$image = imagecreatefromjpeg( 'http://mysite.com/example.jpg' );
$dimensions = null;
getimagesize( $image, $dimensions );
echo 'width = ' . $dimensions[0];

I haven't tested the code, you may need to write the file first....

Thanks Bambii7 for your reply. I tried the examples in the link provided by you. But width and height is coming blank.

Can u please share a working example.
