Regular Expression Matching

Find a regular match PHPcode $ s = 'e3etc56-542NA1220156542N310363ZA0C0331 '; preg_match_all ('/([a-zA-Z0-9] \ w {1}) ([\ w |-] {10 }) \ w \ d (\ d {4}) | \ w {5} \ w find a regular match

PHP code

  $s = 'E3ETC56-542NA1220156542N31036 3ZA0C0331';preg_match_all('/([a-zA-Z0-9]\w{1})([\w|-]{10})\w\d(\d{4})|\w{5} \w{5}/', $s, $r);print_r($r);

Expected result:

XML code

  Array(    [0] => Array        (            [0] => E3ETC56-542NA12201            [1] => 31036 3ZA0C        )    [1] => Array        (            [0] => E3            [1] =>         )    [2] => Array        (            [0] => ETC56-542N            [1] =>         )    [3] => Array        (            [0] => 2201            [1] =>         ))

If $ s = 'd ETC56-542NA1210756542N31036 3ZA0C0154 ', this regular expression preg_match_all ('/([a-zA-Z0-9] \ w {1}) ([\ w |-] {10 }) \ w \ d (\ d {4}) | \ w {5} \ w {5}/') is incorrect. The expression that can satisfy 'e3etc56-542NA1220156542N31036 3ZA0C0331 'and 'd ETC56-542NA1210756542N31036 3ZA0C0154' is obtained.

------ Solution --------------------
$ S = 'e3etc56-542NA1220156542N31036 3ZA0C0331 ';
Preg_match_all ('/([a-zA-Z0-9] [\ w \ s] {1}) ([\ w |-] {10}) \ w \ d (\ d {4 }) | \ w {5} \ w {5}/', $ s, $ r );
Print_r ($ r );
