> PHP extension for **GTK4** — built with [Zephir](https://zephir-lang.com/). This is **not** the legacy PECL `php-gtk` (PHP 5).

`gtk` exposes GTK4 C APIs to PHP 8.2+ as static methods under `Gtk\GTK\…`. It **binds the library**. It does not orchestrate applications, scenes, or tubes. Downstream PHP (a future `microscrap/gtk`) owns ergonomics and enums.

Linux only (Debian / Ubuntu). Darwin toolkit host is `php-io-extensions/metal`. Windows is excluded.

---

Requirements
------------

[](#requirements)

ComponentMinimumNotesPHP8.2ZTS and NTSGTK44.10.0`pkg-config gtk4` — Debian/Ubuntu package `libgtk-4-dev`OSLinuxDebian and Ubuntu share the same apt namesCompilerC11`gcc` on the Linux boxZephir0.19.xOnly required to regenerate `ext/` (`scripts/prepare-ext.sh`)This repository does **not** compile on macOS. Use `build-linux.sh` on Debian or Ubuntu.

---

Installation (Linux)
--------------------

[](#installation-linux)

Debian and Ubuntu use the same packages, so there is one script:

```
bash build-linux.sh
```

That script:

1. Installs `libgtk-4-dev` + PHP headers if needed
2. Runs `scripts/prepare-ext.sh` if `ext/` has not been generated (needs Zephir)
3. `phpize` → `./configure --enable-gtk` → `make` → install `.so` + `30-gtk.ini`

PIE (after `ext/` is committed):

```
pie install php-io-extensions/gtk
```

---

What this extension is
----------------------

[](#what-this-extension-is)

Opaque `int` handles are GObject pointers. `0` is NULL / failure. PHP GC does **not** free natives — pair create with `gObjectUnref` / `gtkWindowDestroy`.

No PHP class constants. Flag ints live in the app or a future microscrap enum (FULLY UPPERCASE backed cases).

That is the GTK Application run loop.

Examples
--------

[](#examples)

Headless (no display):

```
php examples/proof_of_work.php
```

One window + button (needs `WAYLAND_DISPLAY` or `DISPLAY`):

```
php examples/proof_window.php
```

Orientation ints for `gtkBoxNew` (define in the app, not in this extension):

```
const GTK_ORIENTATION_HORIZONTAL = 0;
const GTK_ORIENTATION_VERTICAL = 1;
```

---

Regenerating `ext/`
-------------------

[](#regenerating-ext)

On Linux, after changing `.zep` files:

```
bash scripts/prepare-ext.sh
```

Then commit the generated `ext/` C (phpize junk is gitignored). Do not run `make` on macOS.
