quoting constants in php: “this is a MY_CONSTANT”

Question

I want to use a constant in PHP, but I also want to put it inside double quotes like a variable. Is this at all possible?

define(\"TESTER\", \"World!\");

Answer 1

I recomend you to use concatenation because:

1. When you use a variable into a double quotes string your visibility is not good;
2. When you use a double quotes string the php can to process slowly;
3. You don't use a constant into a string, because don't have any delimiter to the php knows what is the constant.
