PHP String Reference Complete PHP String Reference

Definition and Usage

The setlocale() function sets locale information.

Locale information is language, monetary, time and other information specific for a geographical area.

This function returns the current locale settings, or FALSE on failure.

Syntax

setlocale(constant,location)

Parameter Description
constant Required. Specifies what locale information should be set.

Available constants:

  • LC_ALL - All of the below
  • LC_COLLATE -  Sort order
  • LC_CTYPE - Character classification and conversion (e.g. all characters should be lower or upper-case)
  • LC_MESSAGES - System message formatting
  • LC_MONETARY - Monetary/currency formatting
  • LC_NUMERIC - Numeric formatting
  • LC_TIME - Date and time formatting
location Required. Specifies what country/region to set the locale information to. Can be a string or an array. If the location is an array, setlocale() will try each array element until it finds a valid language or region code. This is very useful if a region is known under different names on different systems.

Note: To view all available language codes, go to our Language code reference.

Tips and Notes

Note: The setlocale() function changes the locale only for the current script.

Tip: The locale information can be set to system default with setlocale(LC_ALL,NULL)

Example

In this example we will set the locale to US English and then back to default again:

<?php
echo setlocale(LC_ALL,"En-Us");
echo "<br />";
echo setlocale(LC_ALL,NULL);
?>

The output of the code above will be:

English_United States.1252
Norwegian (Bokmål)_Norway.1252
