1.2.230. Constant Order¶
Order of dependency of constants.
Constants, either global or class, may be built using static expression. In turn, this means that constants have now a build order. For example :
The code above leads to the following order : A - B, C. A can be built without constraints, while B and C must be build when A is available. Note that B and C are both dependant on A, but are not dependant on each other.
The resulting tree displays the different relationship between the constants.
Note : define``constants are not considered here. Only ``const constants, global or class.
<?php
// A is an independant global constant
const A = 1;
// B is an dependant global constant : it is built with A
const B = A + 1;
class x {
// x::C is an dependant class constant : it is built with A
const C = A + 3;
}
?>
