Are there specific considerations or best practices for implementing imagewebp() in PHP to ensure optimal image quality and file size?

When using imagewebp() in PHP to generate WebP images, it is important to consider the quality parameter to balance image quality and file size. Setting a higher quality value will result in better image quality but larger file size, while a lower quality value will reduce file size but may compromise image clarity. It is recommended to experiment with different quality values to find the optimal balance for your specific use case. 

// Create a function to convert an image to WebP format with a specified quality
function convertToWebP($sourceImagePath, $outputImagePath, $quality = 80) {
    $sourceImage = imagecreatefromjpeg($sourceImagePath);
    imagewebp($sourceImage, $outputImagePath, $quality);
    imagedestroy($sourceImage);
}

// Example usage
$sourceImagePath = 'input.jpg';
$outputImagePath = 'output.webp';
convertToWebP($sourceImagePath, $outputImagePath, 80);
