A Zig library to enable the writing of PHP extensions in Zig.
This library is extremely early in development and as such, isn't feature complete nor ready for production use. Use at your own risk.
A basic module can be created by creating a Zig file with the following contents:
const php = @import("php");
const std = @import("std");
var test_module = php.Module.init(.{
.name = "test_ext",
.version = "0.0.2",
.allocator = std.heap.page_allocator,
});
// The library will automatically search for these three functions:
// - displayInfo - This is the function called when phpinfo() or php -i is called
// - handleStartup - This is the function called when the module is loaded
// - handleShutdown - This is the function called when the module is unloaded
pub fn displayInfo(_: *const php.ZendModuleEntry) void {
php.printInfoStart();
php.printInfoHeaderMap(.{
.@"test extension support" = "enabled",
});
php.printInfoEnd();
}
pub fn handleStartup(version: usize, module_number: usize) !void {
// do something on startup
}
pub fn handleShutdown(version: usize, module_number: usize) !void {
// make sure our allocated memory is freed
test_module.deinit();
}
pub fn extHello(name: []const u8) void {
std.debug.print("Hello, {s}!\n", .{name});
}
pub fn extFibonacci(n: i64) i64 {
if (n <= 1) {
return n;
}
return extFibonacci(n - 1) + extFibonacci(n - 2);
}
pub fn
// This is the most important function when creating a module as this is what PHP will look for when loading the module
export fn get_module() *php.ZendModuleEntry {
test_module.addFunction("ext_hello", extHello, &.{});
test_module.addFunction("ext_fibonacci", extFibonacci, &.{});
return test_module.create(@This());
}
