How can PHP developers efficiently handle graphic data in variables without resorting to external files?

PHP developers can efficiently handle graphic data in variables by using base64 encoding to convert the image data into a string that can be stored in a variable. This eliminates the need for external image files and allows the graphic data to be easily manipulated and passed around within the PHP script. 

// Load the image file into a variable
$image = file_get_contents('path/to/image.jpg');

// Encode the image data as base64
$base64_image = base64_encode($image);

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