Definition: In an expression, the Operator tells us what action to preform on the Operands. In PHP there are three types of operators:
Mathematical:
+ (plus), - (minus), / (divided by), and * (multiplied by)
Comparison:
> (greater than), < (less than), == (equal to), and != (not equal to)
Boolean:
&& (true if both operands are true), || (true if at least one operand is true), xor (true if ONLY one operand is true), and ! (true if a single operand is false)
Examples:
X == 3 + 4 In this expression == and + are the operands
6 > 10 - 5 In this expression > and - are the operands
X != 7 In this expression != is the operand
