php - 分隔符不能是字母数字或反斜杠

Question

这个正则表达式有什么问题？尽管使用/i.

$tokenregex = '/sid(.*)/i';


$bizresponse=curl_getinfo ($curlop1);
$bizresponse = print_r($bizch);


if (preg_match($tokenregex[1], $bizresponse))

{
do things
}

bizresponse是这个

在if (preg_match($tokenregex[1], $bizresponse))中， 的值$tokenregex[1]是s在此处产生错误。替换$tokenregex[1]为$tokenregex
