使用PHP从文件名中提取数字和前缀

Question

I am currently using the following function to grab the product code number for a filename such as "62017 THOR.jpg"

$number = (int) $value;

Leaving me with 62017

The trouble is some of these files have prefixes which need to be left in place ie "WST 62017.jpg"

So im after WST 62017

not

62017

Could someone help me, either redo what im using or alter ?

Answer 1

replace all characters except the numbers from the image name and get only numbers.

  $number  = preg_replace("~[^0-9]~", "", $value);
