I have a cookie with the following data:
我有一个带有以下数据的cookie:
.somesite.com TRUE / FALSE 1315605660 lang en
.somesite.com TRUE / FALSE 1314223260 role premium
.somesite.com TRUE / FALSE 1314223260 PHPSESSID 7ah4ppb3bcbubged8pejb05s35
.somesite.com TRUE / FALSE 1314223260 rememberMe 1
.somesite.com TRUE / FALSE 1314223260 email me@email.me

.somesite.com TRUE / FALSE 0 messagingUnread 0
.somesite.com TRUE / FALSE 0 messagingUnreadLastcheck 1313013660
I only want to get the value of the PHPSESSID which in this case is: 7ah4ppb3bcbubged8pejb05s35
我只想得到PHPSESSID的值在这里是:7ah4ppb3bcbubged8pejb05s35
How can I get that value using preg_match?
如何使用preg_match获得该值?
Update:
更新:
So here is the result of var_dump($cookie);
这是var_dump($cookie)的结果;

I tried this:
我试着这样的:
$search_expression = '/PHPSESSID\s+(.*)$/';
preg_match($search_expression, $cookie, $search_result);
And then I var_dump($search_result);
然后我var_dump($ search_result);
array
empty
Not sure what I am doing wrong...
不知道我做错了什么……

You may simply be using preg_match incorrectly. To populate a variable with the results of a search, it would look something like this:
您可能只是不正确地使用preg_match。要用搜索结果填充变量，应该如下所示:
$search_expression = '/PHPSESSID\s+(.*)$/';
preg_match($search_expression, $cookie, $search_result);
Then to reference the specific session ID you would reference $search_result[1], which will match just what is in parentheses (the session ID). So to use this example, try this:
然后，为了引用特定的会话ID，您将引用$search_result[1]，它将匹配括号中的内容(会话ID)。用这个例子，试试这个:
$search_expression = '/PHPSESSID\s+(.*)$/';
if (preg_match($search_expression, $cookie, $search_result)) {
echo "PHP Session ID found.";
$phpsessionid = $search_result[1];
} else {
echo "PHP Session ID not found.";
}
This will help narrow down the problem. If nothing is still returning, then the problem is with the search expression. You might alternately try this if that is the case:
这将有助于缩小问题的范围。如果仍然没有返回，那么问题是搜索表达式。如果是这样，你可以交替尝试一下:
$search_expression = '/PHPSESSID\s+(.*)\s+\.some/';
And if that still doesn't work, try this search expression:
如果还是不行，试试这个搜索表达式:
$search_expression = '/PHPSESSID\s+([a-z0-9]+)\s+\.some/';

If the separator is a tab, or a space or both in a multi-line string:
如果分隔符是制表符，或空格，或两者都是多行字符串:
~[ \t]PHPSESSID[ \t]+(.*)$~m
