String comparing in PHP is one of the most important part of our projects. Comparing strings seems like an easy task but you will have to remember some key differences when using comparison operators

A single equal sign = is the basic assignment operator in PHP. Don't think this sign as "equal to". The variable on left side of = gets set to the value of the expression on the rights.

Comparison operators allow you to compare two values. These operators test two values against each other, and if they relate correctly, the test returns true.
