I have a php string like bellow,
$str= ' <html>------- <style type="text/css">@media only screen and (max-width: 480px) { .message_mobile,.mesage_logo_mobile { width: 100% !important;} } .message_mobile{ width:600px;} /*message_width 600px */</style> -----</html>';
I need to read 600px
from /*message_width 600px */
Is it possible to get that value from the string?
