Is it possible to call JS function through PHP with pib?

Title says it all.

Can I use custom php-extension inside pib?

Usual way to use extension with php is to copy compiled extension into extension_dir and then adding extension=ext-name.o to php.ini.

Is there any way to include some custom extension into pib bundle?

I'm just started to learn something about emacsen, so I yet can't figure solution by myself.

PHP in Python

Something like #8 but for Python.

There is already Python library for executing WebAssembly binaries. How to use it with PHP?

Error code: SIGTRAP

Open https://seanmorris.github.io/php-wasm/ in Chrome (V98).
The page is crashing after 5 seconds.

Add compatibility tests

To make sure all PHP langauge features are supported.

I thinks this project is great! I wanted to tweak PHP for a long time, but couldn't really do it. I have a fun project to compile different languages to wasm and put them together on the same page, I've called it the Wheel of WebAssembly.

To use the PHP part, I need to change the way you build the wasm - I need it to be modularized as I have other emscripten-built sources as well. I have done these changes in my fork and I was wondering it you were interested in pushing them to you as a PR? :-)

Best,
Boyan

PIB doesn’t work in Safari 12

Hi, I’d like to ask you a question. PIB doesn’t work in Safari 12 because of never resolved promise, that returns from WebAssembly.instantiate, which used as fallback. Safari 12 ( and also 13 beta) doesn’t have WebAssembly.instantiateStreaming.
Promise only resolves in Safari 13 beta and all works.
I managed to find out that the problem is in WebAssembly.Memory, which instance used as property in second argument of WebAssembly.instantiate method. Promise had resolved when i removed WebAssembly.Memory instance from properties (it fails later, but anyway).
I tried to change the amount of allocated memory, but it had no effect

Maybe you have some thoughts about workaround of this problem?

Composer packages

Does pib supports implementation of composer packages?

Long-living PHP process and comunication with it

I built a wasm with option allowing run it in web worker and it works fine. But when i run script like this:
echo 1; sleep(5); echo 2;
i getting "12" output only after 5 seconds. I considering is there any way (any possibly build config) to make php interactive? I've tried to build it with CLI enabled (#8 (comment)), but i don't know how to use it properly in browser.

php in nodejs

Hello. How to use PIB in nodejs or how to make PIN (php in nodejs)

Evaluate opcode directly

Can we utilize zend_execute to evaluate opcode directly?

Some benefits:

Reduce code size for faster load time
Skip lexing and parsing for faster startup time

If possible, we can remove the lexer and parser entirely.

Cannot call pib_eval

When using php-web.js generated by the make command, following error occurs.
'Cannot call unknown function pib_eval'.
When I replace files (php-web.*) with in Github Pages (oraoto.github.io/pib), and call to pib_eval succeeds.
Is there a solution ?

A more generic and practical output

I guess that people want to use it like this way:

<script type="text/php">
    // php code here
</script>

so, make it as generic as possible and register it to packagist.org.

Rather than instruct people how to build it, it is more reasonable to provide the output. If my output is the same output as yours, why do i have to build my self while we have the same needs: a common php engine. Let your output be the "official" one.

want to use xml

I want to use xmlwriter and SimpleXML extensions.
Is there a way to enable those extensions?

ReferenceError: window is not defined

I've installed pib as package by:

npm install php-wasm

And I've loaded an instance of the object as per README (into NextJS):

const PHP = require('php-wasm/PhpWeb').PhpWeb;
const php = new PHP;

However I've got the following error:

ReferenceError: window is not defined

What's the best approach to define reference to window?

Memory spike on startup

Is there any solution to lower memory spike on startup? Currently it spikes up to 3GB, then lowers back to 300MB a few seconds later, but this spike can crush page on weak devices

Support for WebAssembly System Interface

Would it be possible to run PHP with WebAssembly System Interface?

WebAssembly is an assembly language for a conceptual machine, not a physical one. This is why it can be run across a variety of different machine architectures.
Just as WebAssembly is an assembly language for a conceptual machine, WebAssembly needs a system interface for a conceptual operating system, not any single operating system. This way, it can be run across all different OSs.
This is what WASI is — a system interface for the WebAssembly platform.
We aim to create a system interface that will be a true companion to WebAssembly and last the test of time. This means upholding the key principles of WebAssembly — portability and security.

It provides portable and secure way to run WASM with system interface. It is also sandboxed.

Performance is not good

It's 10x slower than the normal version.

Contact Info

Hey, Oraoto!
We are so impressed by your contribution to VisualDL and have some good news for you. Can u contact me at [email protected]? Thanks

README should contain example of files to include

Currently, the README includes a howto to publish the js files to include and sentence "Once the library is included in the page".

The sentence should be extended with an example of html code with the exact includes needed.

I'm loading <Drupal/> component by:

const Drupal = dynamic(() => import("../components/Drupal"), {ssr: false});

where Drupal class is defined as:

export default class Drupal extends React.Component {
	constructor(props) {
		super(props);
	}

	componentDidUpdate(prevProps, prevState) {
	}

	async componentDidMount() {

		const php = new PhpWeb;
	}

	render() {
		return (

Any ideas why this error happens? In php-web.js file?

How to add a composer package?

Hi, beginner here.
Can you tell me if it is possible, through this library, to run a simple script that uses this library: https://github.com/nfephp-org/sped-da ?
The script I need to work is one like this: https://github.com/nfephp-org/sped-da/blob/master/examples/nfe/danfe.php, the only difference is that the $xml will be passed by the application.
So far I have been using a server to do this, but it would be really cool if it worked on the client side, after all performance is not a priority and I just want to cut my costs.

Usage in Iodide

It would be great to use PHP in Iodide. It also uses languages (currently only Python) that are compiled to WebAssembly so it should not be hard to do this.

For details how to do this see iodide-project/iodide#1637.

Compiling newer PHP version

are there any plans to update the PHP version, for example 8 or 8.1.

I've tried to compile PHP 8.1.6 with latest Emscripten and am getting the following error:

shared:ERROR: /src/php-8.1.6/Zend/asm/make_x86_64_sysv_elf_gas.S: Input file has an unknown suffix, don't know what to do with it!

make: *** [Zend/asm/make_x86_64_sysv_elf_gas.lo] Error 1

could anyone help with this? I'll gladly invest some time into updating this project, I really like the concept of PHP WASM. Thanks!

Correct the readdir patch

Currently, the patch skip php_readdir_r function entirely.

echo newline

Example code:

<?php

echo "foo\nbar";

it prints foobar and it's not about html ignoring newline, the output is "foobar" in inspector.

JavaScript Alternative(s)

I also see great potential of how this could be used, as JavaScript has been reputable for its security issues. As a result, other methods are being sought out to harden websites. Looking through the code on the README, it appears that to run the PHP script in the browser, it requires a little JS. Even though this, in of itself, is absolutely incredible for it to be client-sided, I was wondering if any work-arounds or alternatives have been proposed for this project in the long run.

Memroy leak

How to reproduce:

Run this code about 31 times:

<?php

Nice pib = php wasm - header(location); doesn't work

Hello everyone,.

I would like to test pib with header("http://google.com"); but it seems empty?

How do I check?

I never knew that php in wasm. Nice idea - It looks like embedding binary / script into websites - if webspace has not php and mysql than they evade with wasm. That is nice idea!

I have tested with Ubuntu 18.04 without php7.2
I thought wordpress should "embed" in wasm than they don't worry to protect if hackers try to hack to wasm files because wasm is protected file for any websites, right?

I have found before C# in wasm mono.wasm = finish!
c++/c in wasm = finish
php in wasm = finish but sometimes can't work with include or header()
js / ts in wasm ????
ruby or python in wasm ????
perl, lua or any scripts in wasm ????

Providing stub STDOUT/STDERR resources

Is that something you'd be interested in a PR for? php embed differs from a regular CLI in that it doesn't provide these (but echo works)

I have this working in a fork - https://github.com/TysonAndre/phan-demo/blob/79d6df9950789ebf54cf3c798f772df8a76e887e/pib_eval.c#L16-L54

The fork runs a static analyzer (using STDERR) in a browser, by using a preloaded phar file on disk. https://tysonandre.github.io/phan-demo/

Alternately, a regular define+fopen in pure php before the script in question may work more reliably.

Compile with icu ?

Could be php wasm compile with icu for using awesome php intl library in client side ?

Needs a license.

I'd love to know what the terms of reuse were on this code. I'd hope for something Apache-like but even the GPL would be cool.

falling back to ArrayBuffer instantiation

great work!

long time php fan here.
have no direct use of this, but i love it!
