When working with PHP, you may need to read a locale script subtag. This guide explains the operation, shows what its arguments mean, and uses three separate examples to make the result easier to understand.
Locale::getScript: The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
What Is Locale::getScript in PHP?
Read a locale script subtag. The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
Syntax:
Locale::getScript(string $locale): ?string
Parameters and return value: The signature above identifies the arguments and return type where the API has a single call. For topic guides, follow the sequence of calls in the examples. Always distinguish a returned value from an object or variable modified by reference.
Important: The script may be omitted even when a language normally uses a particular writing system.
Example 1: Basic Usage
This example introduces the operation with a short and predictable input.
<?php
var_dump(Locale::getScript("zh_Hant_TW"));
The code focuses on the main operation. The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
Example 2: Another Case
Now compare a different input, locale, date, or option to see another part of the behavior.
<?php
var_dump(Locale::getScript("en_US"));
What changes? The script may be omitted even when a language normally uses a particular writing system.
Practical Example: Applying It in an Application
Use the following separate example as a starting point for a small application task. Check any extension or environment requirements below before running it.
<?php
$examples = ["sr_Cyrl_RS", "sr_Latn_RS"];
foreach ($examples as $localeId) {
echo $localeId . ": " . Locale::getScript($localeId) . PHP_EOL;
}
The practical example demonstrates how to apply this operation to multiple values, a reusable task, or a validated input. The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
Important Behavior and Edge Cases
- Core behavior: The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
- Inputs and results: The script may be omitted even when a language normally uses a particular writing system.
- Alternatives: Locale::parseLocale() returns multiple subtags in one call.
- Compatibility: The intl extension is required.

|---|---|
Locale::getScript | Read a locale script subtag. |
| Related PHP approach | Locale::parseLocale() returns multiple subtags in one call. |
Common Beginner Mistakes
| Mistake | Correct Approach |
|---|---|
| Using an incorrect input or option | The script may be omitted even when a language normally uses a particular writing system. |
| Confusing this API with a related operation | Locale::parseLocale() returns multiple subtags in one call. |
| Assuming output is identical across environments | Check return values and required extensions or versions. The intl extension is required. |
Key Takeaways
- Locale::getScript helps you read a locale script subtag.
- The script distinguishes writing systems such as Latin and traditional Chinese when the locale names one.
- The script may be omitted even when a language normally uses a particular writing system.
Use Locale::getScript when you need to read a locale script subtag. Start with the first example, compare the second, and adapt the practical example to your inputs. Confirm the return value and environment requirements before adding it to production code.
