When working with PHP, locale_parse can help with a specific task: splits a locale identifier into its language, script, region and variant components.
This guide shows what locale_parse does, how to use it in code, and which details you should check before relying on the result.
What Is locale_parse in PHP?
Splits a locale identifier into its language, script, region and variant components.
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 locale_parse with a direct PHP expression.
<?php
if (function_exists("locale_parse")) print_r(locale_parse("en_US"));
The code is an illustration; its result depends on the relevant PHP extension, runtime state and input.
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
if (function_exists("locale_parse")) print_r(locale_parse("zh_Hans_CN"));
The code is an illustration; its result depends on the relevant PHP extension, runtime state and input.
Practical Example
Here is a small scenario illustrating how locale_parse 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
$locale = "sr_Latn_RS"; if (function_exists("locale_parse")) { $parts = locale_parse($locale); echo $parts["language"] ?? "unknown"; }
The code is an illustration; its result depends on the relevant PHP extension, runtime state and input.
Important Behavior and Edge Cases
- Core behavior: Splits a locale identifier into its language, script, region and variant components.
- Important limitation: Requires intl, and not every locale includes every component.
- Production use: Check return values and handle failures before acting on the result.

Key Takeaways
- Splits a locale identifier into its language, script, region and variant components.
- Requires intl, and not every locale includes every component.
- Test the function with relevant inputs before using it in production.
