Preg split或preg match从具有已知和常量模式的字符串中提取

Question

I have a database filled with product names, all of wich follow a strict and identical naming pattern like this European 222/555/111 obtained I want to run a 'for each row in table' little php script and extract the 3 substrings in part 222/555/111 and add the three in separate columns but I'm failing to do the extraction.Should I use preg_split or preg_match? My strings all start with the word 'European' then a space and after that the three options I need separated with /, these could also be only 2 characters like European 96/43/55c strings strings

Should have $option1 = 222 $option2 = 555 $option3 = 111

Answer 1

I'd use preg_match:

$string = 'European 222/555/111 obtained';

if (preg_match('~European ([^/]+)/([^/]+)/([^/\s]+)~', $string, $matches)) {
    print_r($matches);
}

Output:

Array
(
    [0] => European 222/555/111
    [1] => 222
    [2] => 555
    [3] => 111
)

Explanation:

~               : regex delimiter
  European\s+   : literally "European" followed by one or more space
  ([^/]+)       : match everything that is not a slash and store in group 1
  /             : a slash
  ([^/]+)       : match everything that is not a slash and store in group 2
  /             : a slash
  ([^/\s]+)     : match everything that is not a slash or a space and store in group 3
~               : regex delimiter
