public apc_define_constants ( string $key, array $constants, boolean $case_sensitive = true ) : boolean | ||
$key | string | The key serves as the name of the constant set being stored. This key is used to retrieve the stored constants in apc_load_constants(). |
$constants | array | An associative array of constant_name => value pairs. The constant_name must follow the normal constant naming rules. value must evaluate to a scalar value. |
$case_sensitive | boolean | The default behaviour for constants is to be declared case-sensitive; i.e. CONSTANT and Constant represent different values. If this parameter evaluates to FALSE the constants will be declared as case-insensitive symbols. |
return | boolean | Returns TRUE on success or FALSE on failure. |
