Are there any best practices for ensuring that text fits within specified boundaries on an image in PHP, such as automatically adjusting line breaks?

When adding text to an image in PHP, it's important to ensure that the text fits within specified boundaries to maintain readability and aesthetics. One way to achieve this is by automatically adjusting line breaks based on the width of the image. This can be done by calculating the width of the text using the imagettfbbox() function and comparing it to the width of the image. If the text exceeds the width, line breaks can be added at appropriate positions to fit within the boundaries. 

```php
// Set the maximum width for the text
$maxWidth = 200;

// Sample text to be added to the image
$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";

// Font size and font file
$fontSize = 12;
$fontFile = 'path/to/font.ttf';

// Create a new image with specified width and height
$image = imagecreatetruecolor($maxWidth, 100);

// Set the text color
$textColor = imagecolorallocate($image, 255, 255, 255);

// Calculate the width of the text
$textWidth = imagettfbbox($fontSize, 0, $fontFile, $text)[2] - imagettfbbox($fontSize, 0, $fontFile, $text)[0];

// Check if text width exceeds the maximum width
if ($textWidth > $maxWidth) {
    // Split the text into words
    $words = explode(' ', $text);
    $lines = [];
    $line = '';

    foreach ($words as $word) {
        $testLine = $line . ' ' . $word;
        $testWidth = imagettfbbox($fontSize, 0, $fontFile, $testLine)[2] - imagettfbbox($fontSize, 0, $fontFile, $testLine)[0];

        if ($testWidth <= $maxWidth) {
            $line = $testLine;
        } else {
            $lines[] = $line;
            $line = $word;
        }
    }

    $lines[] = $line;

    // Output the text with line breaks
    $y = 20;
    foreach ($lines as $line) {
        imagettftext($image, $fontSize, 0, 10, $y, $textColor, $fontFile, $line);
        $y += 20;
    }
} else {
    // Output the text without
