How can I Enable Webp support in php GD library in MAC

Question

I have installed PHP PHP 7.2.0beta3 using homebrew. The phpinfo shows that the webmp support is enabled,

But when i try to convert an image using a wrapper class it shows this error:

Uncaught Error: Call to undefined function imagewebp() in /Users/rakibtg/Projects/PHP-ImageToWebp/ImageToWebp.php:37 Stack trace ...

How I can enable webp support as well in macOS using homebrew php installed environment?

Where do you see WebP on that list? WBMP ≠ WebP. – Nov 24 '17 at 06:14 — , Nov 24 '17 at 06:14

Try the following:

brew reinstall php72 --with-webp

Or, failing that, try:

brew rm php72
brew install webp
brew install php72 --with-webp

In general, you can find the options available for any given package with:

brew options <PACKAGENAME>

For example:

brew options homebrew/php/php72
