求一个正则匹配
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);
得到结果:
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] =>
)
)
现在如果$s = 'D ETC56-542NA1210756542N31036 3ZA0C0154',这个正则的表达式 preg_match_all('/([a-zA-Z0-9]\w{1})([\w|-]{10})\w\d(\d{4})|\w{5} \w{5}/')就不对了。求既能满足‘E3ETC56-542NA1220156542N31036 3ZA0C0331’,又能‘D ETC56-542NA1210756542N31036 3ZA0C0154’结果的表达式。

$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);
