# Translations in PHP files

Translations in PHP files work straight-forward. Translations functions such as `__()` and `_n()` are part of the WordPress core. Therefore, they are available globally and do not have to be imported.

## Usage of localization functions

### `__()`

The function `__()` retrieves the translation of `$text`. This function is available both for PHP & JS/TS.

```php
// Schema
$translation = __( string $text, string $domain = 'default' );

// Example
$translation = __( 'Place Order', 'woo-gutenberg-products-block' );
```

See also <https://developer.wordpress.org/reference/functions/__/>.

### `_e()`

The function `_e()` displays the translation of `$text`. This function is only available for PHP.

```php
// Schema
_e( string $text, string $domain = 'default' );

// Example
_e( 'Place Order', 'woo-gutenberg-products-block' );
```

See also <https://developer.wordpress.org/reference/functions/_e/>.

### `_ex()`

The function `_ex()` displays the translated string with gettext context. This function is only available for PHP.

```php
// Schema
_ex( string $text, string $context, string $domain = 'default' );

// Example
_ex( 'Place Order', 'Place order button text', 'woo-gutenberg-products-block' );
```

### `_n()`

The function `_n()` translates and retrieves the singular or plural form based on the supplied number. This function is available both for PHP & JS/TS.

```php
// Schema
$translation = _n( string $single, string $plural, int $number, string $domain = 'default' );

// Example
$translation = sprintf(
    /* translators: %s number of products in cart. */
    _n(
        '%d product',
        '%d products',
        absint( $category->count ),
        'woo-gutenberg-products-block'
    ),
    absint( $category->count )
);
```
