Certainly, here's a simple PHP code example to upload an image, improve its quality, and display it:
```php
<!DOCTYPE html>
<html>
<head>
<title>Image Upload and Quality Improvement</title>
</head>
<body>
<?php
if (isset($_POST['submit'])) {
// Check if an image was uploaded
if ($_FILES['image']['error'] == UPLOAD_ERR_OK) {
$image = $_FILES['image']['tmp_name'];
// Load the image and improve its quality
$improvedImage = imagecreatefromjpeg($image);
// Perform additional quality improvement operations if needed
// For example: imagecopyresampled() to resize the image
// Save the improved image
imagejpeg($improvedImage, 'improved_image.jpg');
// Display the improved image
echo '<img src="improved_image.jpg" alt="Improved Image">';
} else {
echo 'Image upload failed. Please try again.';
}
}
?>
<form method="post" enctype="multipart/form-data">
<input type="file" name="image">
<input type="submit" name="submit" value="Upload and Improve Image">
</form>
</body>
</html>
```
This code creates a simple HTML form for uploading an image. When the form is submitted, PHP processes the uploaded image, improves its quality (in this case, it simply creates a copy), and displays the improved image. You can add more quality improvement operations as needed.
