How can variables be passed without using <form> in PHP?

To pass variables without using a <form> in PHP, you can use URL parameters or session variables. URL parameters can be passed through the URL and accessed using the $_GET superglobal array. Session variables can be set using session_start() and accessed throughout the session. This allows you to pass variables between different pages without the need for a form. 

// Passing variables using URL parameters
// Sending page
&lt;a href=&quot;receiving_page.php?variable_name=value&quot;&gt;Link&lt;/a&gt;

// Receiving page (receiving_page.php)
&lt;?php
if(isset($_GET[&#039;variable_name&#039;])){
    $variable = $_GET[&#039;variable_name&#039;];
    echo $variable;
}
?&gt;

// Passing variables using session variables
// Sending page
&lt;?php
session_start();
$_SESSION[&#039;variable_name&#039;] = &#039;value&#039;;
?&gt;

// Receiving page
&lt;?php
session_start();
if(isset($_SESSION[&#039;variable_name&#039;])){
    $variable = $_SESSION[&#039;variable_name&#039;];
    echo $variable;
}
?&gt;
