php-wasm-intl can be loaded via dynamic imports:

const php = new PhpWeb({sharedLibs: [
    await import('https://unpkg.com/php-wasm-intl')
]});

The following supporting libraries will automatically be pulled from the package:

• libicuuc.so
• libicutu.so
• libicutest.so
• libicuio.so
• libicui18n.so
• libicudata.so

You can rely on the default loading behavior if all .so files are served from the same directory as your .wasm files.

const php = new PhpWeb({sharedLibs: ['php8.3-intl.so']});

If you're loading the library manually, you'll need to load icudt72l.dat into the /preload directory:

const sharedLibs = [`https://unpkg.com/php-wasm-intl/php\${PHP_VERSION}-intl.so`];

const files = [
    {
        name: 'icudt72l.dat',
        parent: '/preload/',
        url: 'https://unpkg.com/php-wasm-intl/icudt72l.dat'
    }
];

const php = new PhpWeb({sharedLibs, files});

You can provide a callback as the locateFile option to map library names to URLs:

const locateFile = (libName) => {
    return `https://my-example-server.site/path/to/libs/${libName}`;
};

const php = new PhpWeb({locateFile, sharedLibs: ['php8.3-intl.so']});

The following options may be set in .php-wasm-rc for custom builds of php-wasm & php-cgi-wasm.

When compiled as a dynamic, or shared extension, this will produce the extension php-8.𝑥-intl.so & the following libraries:

• libicuuc.so
• libicutu.so
• libicutest.so
• libicuio.so
• libicui18n.so
• libicudata.so

The following data file will also be produced, and should be loaded to the /preload directory:

• icudt72l.dat
