create session in wordpress

Add the following code to your theme's functions.php file to create a session in WordPress:

function start_session() {
    if ( ! session_id() ) {
add_action( 'init', 'start_session', 1 );

Explanation: 1. The function start_session() declares a new function to start a session. 2. Inside the function, session_id() checks if a session has already been started. If not, the session_start() function is called to start the session. 3. The add_action( 'init', 'start_session', 1 ) line hooks the start_session function to the init action with a priority of 1, ensuring that the session is started early in the WordPress loading process.
