PHP_Compat::loadConstant() -- Load a constant, or an array of constants

Synopsis

require_once 'PHP/Compat.php';

mixed PHP_Compat::loadConstant (mixed $constant)

Description

Loads a constant, or an array of constants.

Parameter

mixed $constant: The name, or an array of names, of constants to load

Return value

mixed

TRUE if the constant was loaded.

FALSE if the constant was not loaded. Either unable to be included or already defined.

If you specified an array of constants to load, an array of TRUE/FALSE values is returned.

Example

Example 54-1. Loading a constant with the class:

<?php
require_once 'PHP/Compat.php';

// load E_STRICT
PHP_Compat::loadConstant('E_STRICT');

// load E_STRICT, and PATH_SEPATATOR
PHP_Compat::loadConstant(array('E_STRICT', 'PATH_SEPARATOR'));

// load the STD group of constants (STDIN, STDOUT, STDERR)
PHP_Compat::loadConstant('STD');
?>

You may also load a constant without using the class.

Example 54-2. Loading a constant manually:

<?php
require_once 'PHP/Compat/Constant/E_STRICT.php';
?>
