PHP preg_split & [0-9] 循环

发布于 2024-11-24 04:49:31 字数 321 浏览 6 评论 0原文

您好，我需要根据此“动态”分隔符将字符串拆分为数组：

String &Acirc;&nbsp; 1&Acirc;&nbsp; String2

String2 &Acirc;&nbsp; 65&Acirc;&nbsp; String3

Â  之间的数字是可变的......字符串也可以包含 Â  也是如此，所以 str_replace 或爆炸是没有用的（对我来说）

Hi i need to split a string into an array based on this "dynamic" separator:

String Â  1Â  String2

String2 Â  65Â  String3

The number between the Â it's variable... also the strings could contain Â too, so a str_replace or an explode it's useless (for me)

$str = "String Â  1Â  Â ";
$result = preg_split('/ Â  [\d]+Â  /', $str);
print_r($result);

Array
(
    [0] => String
    [1] => Â 
)

解释：

# Match the characters “ Â  ” literally « Â  »
# 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 “Â  ” literally «Â  »

$str = "String Â  1Â  Â ";
$result = preg_split('/ Â  [\d]+Â  /', $str);
print_r($result);

Array
(
    [0] => String
    [1] => Â 
)

Explanation:

# Match the characters “ Â  ” literally « Â  »
# 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 “Â  ” literally «Â  »
