How can PHP beginners approach the task of resizing images to a square format without distortion?

When resizing images to a square format without distortion, beginners can achieve this by using the `imagecopyresampled` function in PHP. This function allows for resizing an image without distortion by cropping or padding the image to fit a square aspect ratio. By calculating the dimensions needed to resize the image to a square format and then applying the `imagecopyresampled` function, beginners can successfully resize images without distortion. 

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

// Get the original image dimensions
$original_width = imagesx($original_image);
$original_height = imagesy($original_image);

// Calculate the new dimensions for a square format
if ($original_width > $original_height) {
    $new_width = $original_height;
    $new_height = $original_height;
} else {
    $new_width = $original_width;
    $new_height = $original_width;
}

// Create a new square canvas
$square_image = imagecreatetruecolor($new_width, $new_height);

// Resize and crop the original image to fit the square canvas
imagecopyresampled($square_image, $original_image, 0, 0, 0, 0, $new_width, $new_height, $original_width, $original_height);

// Save the resized square image
imagejpeg($square_image, 'resized.jpg');

// Free up memory
imagedestroy($original_image);
imagedestroy($square_image);
