Hi I am new in php and when I came across define(‘INCLUDE_CHECK’,true); I was not able to understand what it is for?

Pls. explain.

Thanks!

Answer 1

This is a constant that is being used by that application later. Define() is used to create these constants. Typically this is used for configuration data. To use this constant later, you simply use the string INCLUDE_CHECK in code like it were a variable without the $.

so

if(INCLUDE_CHECK)
{
// Do code that only should happen if you want it to.
}
