What are the potential pitfalls of using imagecreatefrompng() in PHP for handling PNG files?

One potential pitfall of using imagecreatefrompng() in PHP for handling PNG files is that it may not support all PNG file types, resulting in errors or corrupted images. To solve this issue, you can use imagecreatefromstring() instead, which can handle a wider range of PNG file types. 

// Example of using imagecreatefromstring() to handle PNG files
$png_data = file_get_contents('image.png');
$image = imagecreatefromstring($png_data);

// Check if the image was created successfully
if($image !== false) {
    // Image processing code here
    // Remember to free up memory with imagedestroy($image) when done
} else {
    echo 'Unable to create image from PNG file.';
}
