hai im newbie as regex我想先在php中问一些关于regex的东西，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

和我的代码是这样的：

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

我想要的就是得到像这样的数组：

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"

你们可以帮我吗？

这会工作

（如OP注释中所述，字符串sessionid始终以开头IGSC）

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

正则表达式演示

记住，[^\s] -> [\S]。所以你可以随意使用

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);

你的结果是matches[1]和matches[2]
