/*
* Here provide a series of helpers in the str_ $ TRUE_ $ FALSE format ( you can
* also expand some helpers as needed ) , where $ TRUE and $ FALSE are their
* corresponding literal strings . These helpers can be used in the printing
* and also in other places where constant strings are required . Using these
* helpers offers the following benefits :
* 1 ) Reducing the hardcoding of strings , which makes the code more elegant
* through these simple literal - meaning helpers .
* 2 ) Unifying the output , which prevents the same string from being printed
* in various forms , such as enable / disable , enabled / disabled , en / dis .
* 3 ) Deduping by the linker , which results in a smaller binary file .
