Question

hai im newbie as regex我想在php中询问有关正则表达式的一些内容首先我有这样的字符串：

#HttpOnly_www.xyz.com   FALSE   /   TRUE    1468386389  sessionid IGSC4c9b34af03c4d6a83e9ac949d5f32a6f9a50ced1362b1797cec54ceac3c57110%3Agp888l8neqxFTtJHXMPWkQfIQ9uKv113%3A%7B%22_token_ver%22%3A2%2C%22_auth_user_id%22%3A2251871689%2C%22_token%22%3A%222251871689%3ApZdi2i1V6EtoR3p7CgADOomNZLxUta74%3A9d2adf87ebeeb84899dba1a383ef822aeb0a9b7d13c50b6052df407f25c676a2%22%2C%22asns%22%3A%7B%222600%3A3c02%3Ae001%3A1a96%3A28ed%3Ab4b%3Ab8bb%3A2c5f%22%3A17025%2C%22time%22%3A1460610396%7D%2C%22_auth_user_backend%22%3A%22accounts.backends.CaseInsensitiveModelBackend%22%2C%22last_refreshed%22%3A1460610395.854883%2C%22_platform%22%3A4%7D   www.xyz.com FALSE   /   FALSE   1460613989  s_network

我的代码是这样的：

$cotext = file_get_contents($cookieFile);
preg_match('/(sessionid)\s[^\S]*/', $cotext, $id);

我想要的就是得到这样的数组：

array [0] => "sessionid"
array [1] => "IGSC4c9b34af03c4d6a83e9ac949d5f32a6f9a50ced1362b1797cec54ceac3c57110%3Agp888l8neqxFTtJHXMPWkQfIQ9uKv113%3A%7B%22_token_ver%22%3A2%2C%22_auth_user_id%22%3A2251871689%2C%22_token%22%3A%222251871689%3ApZdi2i1V6EtoR3p7CgADOomNZLxUta74%3A9d2adf87ebeeb84899dba1a383ef822aeb0a9b7d13c50b6052df407f25c676a2%22%2C%22asns%22%3A%7B%222600%3A3c02%3Ae001%3A1a96%3A28ed%3Ab4b%3Ab8bb%3A2c5f%22%3A17025%2C%22time%22%3A1460610396%7D%2C%22_auth_user_backend%22%3A%22accounts.backends.CaseInsensitiveModelBackend%22%2C%22last_refreshed%22%3A1460610395.854883%2C%22_platform%22%3A4%7D"

你能帮助我吗？

Answer 1

这将有效

（在评论中提及OP，sessionid之后的字符串始终以IGSC开头）

(sessionid)\s+(IGSC[^\s]+)

<强> Regex Demo

记住，[^\s] -> [\S]。所以你可以按照自己的意愿使用任何一个

PHP代码

$re = "/(sessionid)\\s+(IGSC[^\\s]+)/"; 
$str = "#HttpOnly_www.xyz.com   FALSE   /   TRUE    1468386389  sessionid IGSC4c9b34af03c4d6a83e9ac949d5f32a6f9a50ced1362b1797cec54ceac3c57110%3Agp888l8neqxFTtJHXMPWkQfIQ9uKv113%3A%7B%22_token_ver%22%3A2%2C%22_auth_user_id%22%3A2251871689%2C%22_token%22%3A%222251871689%3ApZdi2i1V6EtoR3p7CgADOomNZLxUta74%3A9d2adf87ebeeb84899dba1a383ef822aeb0a9b7d13c50b6052df407f25c676a2%22%2C%22asns%22%3A%7B%222600%3A3c02%3Ae001%3A1a96%3A28ed%3Ab4b%3Ab8bb%3A2c5f%22%3A17025%2C%22time%22%3A1460610396%7D%2C%22_auth_user_backend%22%3A%22accounts.backends.CaseInsensitiveModelBackend%22%2C%22last_refreshed%22%3A1460610395.854883%2C%22_platform%22%3A4%7D   www.xyz.com FALSE   /   FALSE   1460613989  s_network"; 

preg_match($re, $str, $matches);

您的结果位于matches[1]和matches[2]

Answer 2

你的匹配模式字符串应该是 "/(sessionid)\s(\S*)/"。

1.因为\ s匹配空格，\ S匹配非空格。你不应该在\ S之前放^。

2.如果要捕获sessionid，则应在\ S *周围添加括号。

所以，$id现在是

    Array
(
    [0] => sessionid IGSC4c9b34af03c4d6a83e9ac949d5f32a6f9a50ced1362b1797cec54ce

请注意$id[0]是完整的匹配字符串，$id[1]和$id[2]匹配括号分别。

Answer 3

你的正则表达式中有2个小错误。首先，你的第二组需要一个＆＃34;（＆＃34;以便你可以访问它其次，如果您使用\ S，则不需要^。所以，它看起来像这样：

(sessionid)\s+(\S*)

Here you can test you regex's

正则表达式，在第一个单词后获取所有字符直到空格或输入
