数组过滤 - php

Question

echo $cookie[4];

Result:

#HttpOnly_bacohuracm FALSE / TRUE 0 PHPSESSID 3A8DB8BE067954EE327A56F7F8D8B19C 

i wanna delete this part:

#HttpOnly_bacohuracm FALSE / TRUE 0 PHPSESSID 

and wanna get only this part:

3A8DB8BE067954EE327A56F7F8D8B19C 

i tried preg_match, it has given a null result. i tried some other ways, and gotten same null result and still couldn't figure out how i can do this job with php.. please give me some advice

Answer 1

foreach($cookie as $value)
    echo substr($value, strpos($value, 'PHPSESSID')+10);

Would work

Answer 2

To return only what you're looking for:

$source = "#HttpOnly_bacohuracm FALSE / TRUE 0 PHPSESSID 3A8DB8BE067954EE327A56F7F8D8B19C";
preg_match("/PHPSESSID (\w+)$/", $source, $matches);
print $matches[1];

If this still returns null, is error text being suppressed? Is there anything related in the logs?
