imagewebp — Output a WebP image to browser or file
imagewebp ( resource $image [, mixed $to = null [, int $quality = 80 ]] ) : bool
Outputs or saves a WebP version of the given image.
image
An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
to
The path or an open stream resource (which is automatically being closed after this function returns) to save the file to. If not set or null, the raw image stream will be outputted directly.
quality
quality ranges from 0 (worst quality, smaller file) to 100 (best quality, biggest file).
Returns true on success or false on failure.
However, if libgd fails to output the image, this function returns true.
Example #1 Saving an WebP file
<?php // Create a blank image and add some text $im = imagecreatetruecolor(120, 20); $text_color = imagecolorallocate($im, 233, 14, 91); imagestring($im, 1, 5, 5, 'WebP with PHP', $text_color); // Save the image imagewebp($im, 'php.webp'); // Free up memory imagedestroy($im); ?>
