What common mistakes can lead to errors in PHP scripts when trying to draw with PHP?

Common mistakes that can lead to errors in PHP scripts when trying to draw with PHP include missing or incorrect syntax in the code, not properly defining variables or functions, and not including necessary libraries or dependencies. To avoid these errors, make sure to double-check your syntax, properly define all variables and functions, and include any necessary libraries or dependencies before running the script. 

// Example of properly defining variables and using correct syntax for drawing with PHP

<?php
// Define variables for image width and height
$width = 500;
$height = 300;

// Create a blank image with the specified width and height
$image = imagecreatetruecolor($width, $height);

// Set the background color of the image to white
$white = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $white);

// Output the image as a PNG file
header('Content-Type: image/png');
imagepng($image);

// Free up memory by destroying the image resource
imagedestroy($image);
?>
