How can PHP be used to pass variables between pages effectively?
To pass variables between pages effectively in PHP, you can use sessions or URL parameters. Sessions allow you to store variables across multiple pages for a specific user, while URL parameters can pass variables through the URL. Both methods are commonly used in web development to maintain state and share data between pages.
// Using sessions to pass variables between pages
session_start();
$_SESSION['variable_name'] = 'value';
// Using URL parameters to pass variables between pages
// Page 1
$variable = 'value';
header("Location: page2.php?variable=$variable");
// Page 2
$variable = $_GET['variable'];
echo $variable;
