php 7.2 - ini_set fails to set session variables ' PHP 7.2.0 and higher

Hey everyone,

I encountered a similar issue with session variables in PHP 7.2.0, and although the `ini_set` function didn't work for me, I found a different solution that might help.

Instead of trying to set session variables using `ini_set`, I used the `session_start` function and modified the session variables directly in my code.

Here's an example:

php
session_start();

$_SESSION['save_handler'] = 'memcached';

$_SESSION['save_path'] = 'localhost:11211';

Hey everyone,

I encountered a similar issue with `ini_set` and session variables in PHP 7.2.0, and here's what worked for me. Instead of using `ini_set`, I used the `session_set_save_handler` function to modify the session variables.

First, ensure that you have the necessary extensions installed and enabled for your desired session save handler. For example, for memcached, make sure you have the Memcached extension installed and enabled in your PHP configuration.

Next, you can create a custom session handler class that implements the `SessionHandlerInterface` interface. Within this class, you can define the desired session save handler functionality, such as connecting to memcached and handling session data storage and retrieval.

Here's a basic example:

php
class CustomSessionHandler implements SessionHandlerInterface

{

    // Implement your desired session save handler functionality here

}



// Set the custom session handler

$handler = new CustomSessionHandler();

session_set_save_handler($handler, true);



// Now you can modify session variables as needed

Hey there,

I faced a similar issue with `ini_set` and session variables in PHP 7.2 recently. After extensive troubleshooting, I discovered that in PHP 7.2 and higher versions, the `ini_set` function does not allow modification of certain session variables for security reasons.

In particular, `ini_set` is blocked from modifying session-related variables such as `session.save_handler` and `session.save_path`. Instead, you'll need to update these settings directly in the `php.ini` file or using the `session_set_save_handler` function.

To change the session save handler, you can edit the `php.ini` file and locate the `session.save_handler` directive. Modify it to the desired handler, like `session.save_handler = memcached` in your case. Don't forget to restart your web server afterward.

For the session save path, you have two options. Either update the `php.ini` file and change `session.save_path` directly, or use `session_save_path` function in your PHP code before session start. For example:

php
session_save_path('localhost:11211');
