在PHP中过滤字符串

Question

I'm looking to get an array of ID's from the following string.

[vc_gallery type="flexslider_fade" interval="3" images="3057,2141,234" onclick="link_image" custom_links_target="_self" img_size="large"]

Ideally, i'd like to look at this string and get an array of the INT values within images. e.g.

array("3057", "2141", "234");

Answer 1

find images value and explode it to receive array

$str = '[vc_gallery type="flexslider_fade" interval="3" images="3057,2141,234" onclick="link_image" custom_links_target="_self" img_size="large"]';

if (preg_match('/images\s*=\s*\"([^\"]+)\"/', $str, $m)) {
   $res = explode(',', $m[1]);
   print_r($res);
}
