How can one ensure that text alignment and sizing on an image created via PHP remains consistent when the text length varies?

When dealing with varying text lengths on an image created via PHP, it is important to dynamically adjust the text alignment and sizing to ensure consistency. One way to achieve this is by calculating the length of the text and adjusting the positioning and font size accordingly. By setting up conditional statements based on the text length, you can ensure that the text remains aligned and sized appropriately on the image. 

<?php

// Sample text to be displayed on the image
$text = "Lorem ipsum dolor sit amet";

// Define image width and height
$width = 800;
$height = 400;

// Create a new image with specified dimensions
$image = imagecreatetruecolor($width, $height);

// Set text color and font size
$textColor = imagecolorallocate($image, 255, 255, 255);
$fontSize = 20;

// Calculate text length and adjust alignment and sizing
$textLength = strlen($text);

if($textLength < 20){
    $x = 50;
    $y = 200;
    $fontSize = 20;
} elseif($textLength >= 20 && $textLength < 40){
    $x = 20;
    $y = 250;
    $fontSize = 18;
} else {
    $x = 10;
    $y = 300;
    $fontSize = 16;
}

// Add text to the image
imagettftext($image, $fontSize, 0, $x, $y, $textColor, 'arial.ttf', $text);

// Output the image
header('Content-type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);

?>
