Aiuto su regex e controllo dimensioni IMG

[k.b]

Non usare le regular expressions, usa http://simplehtmldom.sourceforge.net/

include 'simple_html_dom.php';

$html = str_load_html($post->post_content);

foreach( $html->find('img') as $image ) {
    // qui avrai la width in $image->width
    // la height in $image->height
    // la sorgente in $image->src
}
