答
Do you mean something like this ?
So you would need to use
preg_match_all('/(alt|title|src)=("[^"]*")/i',$img_tag, $img[$img_tag]);
And then foreach them to array.
答
You can use getimagesize()
<?php
list($width, $height, $type, $attr) = getimagesize("http://example.com/image.gif");
?>
<img src="..." width="<?= $width ?> height="<?= $height ?>" />
