Is it possible to directly call a function from a form in PHP?

Yes, it is possible to directly call a function from a form in PHP by specifying the function name in the action attribute of the form tag. When the form is submitted, the specified function will be called. 

<?php

// Function to be called
function myFunction() {
    // Function logic here
    echo "Function called successfully!";
}

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Call the function if form is submitted
    if ($_POST["form_action"] == "myFunction") {
        myFunction();
    }
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
    <input type="hidden" name="form_action" value="myFunction">
    <button type="submit">Call myFunction</button>
</form>
