PHP Operators

Opertors in PHP, and any other prgramming language for that matter, enable us to perfrom tasks on variables and values such as assign, multiply, add, subtract and concatenate them. Operators take the form of symbols (such as + and -) and combinations of symbols (such as ++ and +=).

Operators in PHP work with operands that specify the variables and values that are to be used in the particalar operation. The number and location of tyhese operands in relate to the operators (ie before and/or after the operator) depends on the type of operator in question. In this chapter of PHP Essentials we will exlore each type of operator and explain how they are used in relation to their operands.
