When working with PHP, ngettext can help with a specific task: selects singular or plural translated text using gettext plural rules.
This guide shows what ngettext does, how to use it in code, and which details you should check before relying on the result.
What Is ngettext in PHP?
Selects singular or plural translated text using gettext plural rules.
Usage: The following examples show calls with suitable values. Consult the function parameters described in the examples, especially when optional arguments or extensions are involved.
Example 1: Basic Usage
The first example introduces ngettext with a direct PHP expression.
<?php
echo ngettext("one item", "many items", 1);
Observe the value returned or printed by ngettext and compare it with the input used in this example.
Example 2: A Different Input or Option
This second example demonstrates another input or condition, so you can compare the behavior with the first example.
<?php
echo ngettext("one file", "many files", 3);
Observe the value returned or printed by ngettext and compare it with the input used in this example.
Practical Example
Here is a small scenario illustrating how ngettext can fit into application code. Run the example only in an appropriate development environment if it reads files, changes data, starts processes or connects to a service.
<?php
$count = 4; $template = ngettext("%d photo", "%d photos", $count); echo sprintf($template, $count);
Observe the value returned or printed by ngettext and compare it with the input used in this example.
