What programming languages and technologies should be familiar to achieve the functionality of changing graphics through a form in PHP?

To achieve the functionality of changing graphics through a form in PHP, you should be familiar with HTML for creating the form, PHP for processing the form data and updating the graphics, and possibly JavaScript for handling any client-side interactions. Additionally, knowledge of image manipulation libraries such as GD or Imagick may be necessary to handle the actual graphic changes. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    $newImage = $_POST['new_image'];

    // Update the graphics based on the form input
    // This could involve using GD or Imagick to manipulate images

    // Display a success message
    echo "Graphics updated successfully!";
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <label for="new_image">Enter new image URL:</label>
    <input type="text" name="new_image" id="new_image">
    <button type="submit">Update Graphics</button>
</form>
