英文:
Why PHP Session is Empty Even After session_start()?
问题
I just upgraded the existing version of Apache to 2.4 and MySQL to 8.0. After this upgrade I am facing a strange issue with PHP.
PHP $_SESSION remains an empty array even after calling session_start() function. Here is the code snippet from my PHP file.
session_start();
if(session_id() != ''){
echo '<script>alert("session is active")</script>';
}
else{
echo '<script>alert="'.json_encode($_SESSION).'"</script>';
}
Here you can see the javascript alert with an empty array.
Did anyone ever face such an issue?
Another if condition check in the file is also returning true.
if ($token != $_SESSION[Codes::FORM_TOKEN_ELEMENT]) {
header("location:index.php?msg=inft&auth=" . urlencode(CryptoJsAes::encryptData(0)));
die;
}
Here $token has a value but $_SESSION[Codes::FORM_TOKEN_ELEMENT] does not.
I tried the following code at the top of the page.
if(!isset($_SESSION["ID"])) {
echo "Session Started";
session_start();
$_SESSION["ID"] = rand(78273874,922839929928839);
}
!isset($_SESSION["ID"]) is always returning true.
