How can one prevent unnecessary cURL queries from being executed repeatedly in PHP when using session variables?

To prevent unnecessary cURL queries from being executed repeatedly in PHP when using session variables, you can store the fetched data in a session variable and check if it exists before making a new cURL request. If the data is already stored in the session, you can simply use that instead of making a new query. 

<?php
session_start();

if (!isset($_SESSION['fetched_data'])) {
    $ch = curl_init();
    // cURL request code here
    $fetched_data = curl_exec($ch);
    curl_close($ch);
    
    $_SESSION['fetched_data'] = $fetched_data;
} else {
    $fetched_data = $_SESSION['fetched_data'];
}

// Use $fetched_data as needed
?>
