Operators in PHP

Operator- Here is an example that describes operator. Suppose, we have an expression 6+7, so 6  and 7 are called operands and + is called Operator. Here are various types of operators that are supported by PHP:-

• Arithmetic Operators
• Comparison Operators
• Logical (or Relational) Operators
• Assignment Operators
• Conditional (or ternary) Operators
  
  Arithmetic Operators:-  Here are the five arithmetic operators:-
  1) + :- Adds two operands(X+Y)
  2) - :- Subtracts Second operand from first.(X-Y)
  3) * :- Multiply both Operands(X*Y)
  4) / :- Divide Numerator by Denominator(Y/X)
  5)% :- Modulus Operator and remainder of after an integer division(Y%X)
  6) ++ :- Increment operator, increases integer value by one(X++)
  7) -- :-Decrement operator, decreases integer value by one(X--)
  
  Comparison Operators:- Here are following Comparison Operators:-
  1) == :-Checks if the value of two operands are equal or not, if yes then condition becomes true.
  2) != :-  Checks if the value of two operands are equal or not, if values are not equal then condition becomes true.
  3) >:- Check if Left Operand is greater than right operand.
  4)  < :-Checks if Left operand is less than right operand
  5) >= :- Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.
  6) <= :- Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.
  
  Logical Operators: - Here are following Logical Operators:-
  1) and :- Called Logical AND operator. If both the operands are true then then condition becomes true.
  2) or:- Called Logical OR Operator. If any of the two operands are non zero then then condition becomes true.
  3) && :-Called Logical AND operator. If both the operands are non zero then then condition becomes true.
  4) !! :-Called Logical OR Operator. If any of the two operands are non zero then then condition becomes true.
   5) ! :-Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.
  
   Assignment Operators:- Here are following Assignment Operators:-
  1) =Simple assignment operator, Assigns values from right side operands to left side operand
  2) +=Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand
  3) -=Subtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand
  4)*=Multiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand
  5 /=Divide AND assignment operator, It divides left operand with the right operand and assign the result to left operand
  6)%= Modulus AND assignment operator, It takes modulus using two operands and assign the result to left operand
  
  Conditional Operators:-This operator works on the basis of condition.  This first evaluates an expression for a true or false value and then execute one of the two given statements depending upon the result of the evaluation.Here is one conditional Operator:-
  1) ? : :- Conditional Expression
