What potential pitfalls are present in the code provided for creating a PNG image with text in PHP?

The code provided does not handle errors such as file writing failures or font loading issues. To improve the code, we can add error handling to ensure that the image creation process is robust and reliable. 

<?php
// Set error handling for image creation
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Create a PNG image with text
$im = imagecreate(200, 50);
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
$text = 'Hello, World!';
$font = 'arial.ttf';

// Check if font file exists
if (!file_exists($font)) {
    die('Font file not found.');
}

imagettftext($im, 20, 0, 10, 30, $black, $font, $text);

// Save the image to a file
if (!imagepng($im, 'text_image.png')) {
    die('Failed to save image.');
}

imagedestroy($im);
?>
