How can a PHP variable be read in an HTML form?

To read a PHP variable in an HTML form, you can simply echo the variable value within the form input field. This way, the PHP variable value will be displayed in the input field when the form is loaded. This can be useful for pre-filling form fields with dynamic data from PHP. 

<?php
$variable = "Hello World";
?>

<form action="submit.php" method="post">
    <input type="text" name="input_field" value="<?php echo $variable; ?>">
    <input type="submit" value="Submit">
</form>
