How can PHP beginners avoid common errors when trying to merge text and images using PHP functions?

When trying to merge text and images using PHP functions, beginners often encounter errors due to incorrect syntax or improper handling of image resources. To avoid common errors, it is important to ensure that the image file path is correct, use the appropriate PHP functions to manipulate images, and properly concatenate text with image content.

php 
<?php

// Load the image
$image = imagecreatefromjpeg('image.jpg');

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

// Add text to the image
$text = 'Hello, World!';
imagettftext($image, $fontSize, 0, 10, 50, $fontColor, 'arial.ttf', $text);

// Output the image
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);

?>
