Translations:Manual:Variable/3/en

The term is something of a misnomer because there is nothing variable about a variable. End users cannot change the value of a variable because it is predetermined by a bundle of PHP code that calculates its value. The term "variables" comes from the source of their value: a PHP variable or something that could be assigned to a variable, e.g. a string, a number, an expression, or a function return value.
