Sr. PHP Programmer Interview Question:

What do you mean by having PHP as whitespace insensitive?

Submitted by: Muhammad

Whitespace is the stuff you type that is typically invisible on the screen, including spaces, tabs, and carriage returns (end-of-line characters). PHP whitespace insensitive means that it almost never matters how many whitespace characters you have in a row.one whitespace character is the same as many such characters.
