• __(string $text, string $domain = ‘default’);
• _x(string $text, string $context, string $domain = ‘default’);
• pll_e(string $text);
• pll__(string $text);
• esc_html(string $text);
• esc_html_e(string $text, string $domain = ‘default’);
• esc_html__(string $text, string $domain = ‘default’);
• _n(string $single, string $plural, int $number, string $domain = ‘default’);
• esc_attr_e(string $text, string $domain = ‘default’);
• esc_attr__(string $text, string $domain = ‘default’);

<p><?php pll_e('My text'); ?></p>

<p><?php _e('My another text', 'my_theme'); ?></p>
