preg split - PHP preg_split [0-9] Â

Question

嗨，我需要根据这个"动态"分隔符将一个字符串分割成一个数组:

String   1  String2
String2   65  String3

数字之间的 它的变量…字符串也可以包含 ，所以一个str_replace或一个爆炸它是无用的(对我来说)

Answer 1

$str = "String   1   ";
$result = preg_split('/   [d]+  /', $str);
print_r($result);
Array
(
    [0] => String
    [1] =>  
)

解释:

# Match the characters “   ” literally «   »
# Match a single digit 0..9 «[d]+»
#    Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
# Match the characters “  ” literally «Â  »
