php.js is a resource that offers community-built JavaScript alternatives for PHP functions.

If you want to perform high-level operations on JavaScript platforms such as webbrowsers, node.js, etc, you probably need to write JS that combines its lower-level functions and build it up until you have something useful like:

PHP is a language with many high-level functions and while they're not always implemented as consistently as we'd like (mimicking their underlying C parts), it has a huge following familiar with its functions.

Never let php.js be an excuse not to.

For the this reason we don't offer gigantic php.js packages or compilers anymore.

That said, we do think it's a challenge to port everything and decided to also port low-level PHP functions like

even though it has a perfectly fine (and more performant!) JavaScript counterpart ([String.indexOf](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/String/indexOf)).

Besides the intellectual challenge of seeing how far we could come, porting ALL THE THINGS opens up php.js to be used for

other fun thought excercises such as realtime in-browser debugging/running of PHP code, or running .php files with JavaScript interpreters.

Also, there are quite a few PHP developers that use php.js just to learn how something is done in JavaScript.

And so we see ourselves as this big resource and leave it up to the developer to decide what makes sense to take from it.

Under the motto: "Make it work, then make it work better", we have plently of functions here online that aren't perfect just yet.
