What are some examples of button code in PHP that can execute custom-defined functions?

To execute custom-defined functions in PHP when a button is clicked, you can use a form with a button input element and submit the form to a PHP script that calls the desired function. You can pass the function name as a parameter in the form submission and use that parameter to call the function dynamically in PHP. Example PHP code snippet: 

<?php
// Check if the form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the function name from the form submission
    $functionName = $_POST['functionName'];

    // Call the custom-defined function based on the function name
    if (function_exists($functionName)) {
        $functionName();
    }
}

// Custom-defined functions
function customFunction1() {
    echo "Function 1 executed!";
}

function customFunction2() {
    echo "Function 2 executed!";
}
?>

<form method="post">
    <input type="hidden" name="functionName" value="customFunction1">
    <button type="submit">Execute Function 1</button>
</form>

<form method="post">
    <input type="hidden" name="functionName" value="customFunction2">
    <button type="submit">Execute Function 2</button>
</form>
