Is it possible to display a preview image without saving it on the server first in PHP?

Yes, it is possible to display a preview image without saving it on the server first in PHP by using the data URI scheme. This scheme allows you to embed the image data directly into the HTML document using base64 encoding. By converting the image data to base64 and embedding it in an img tag, you can display the image without saving it on the server. 

<?php
// Path to the image file
$image_path = 'path/to/image.jpg';

// Get the image data
$image_data = file_get_contents($image_path);

// Convert the image data to base64
$base64_image = base64_encode($image_data);

// Display the image using data URI scheme
echo '<img src="data:image/jpeg;base64,' . $base64_image . '" />';
?>
