PHP Operators



Here we have a list of PHP operators that are used in PHP. This is not so much a Tutorial as a reference.

In PHP there are many types of operators.

Operators by Type:

  • Arithmetic Operators
  • Assignment Operators
  • Comparison Operators
  • Logical Operators


  • Below we have tables with these types layed out to help you better understand their uses.



    Arithmetic Operators

    Operator Description Example Result
    + Addition x=2
    x+2
    4
    - Subtraction x=2
    5-x
    3
    * Multiplication x=4
    x*5
    20
    / Division 15/5
    5/2
    3
    2.5
    % Modulus (division remainder) 5%2
    10%8
    10%2
    1
    2
    0
    ++ Increment x=5
    x++
    x=6
    -- Decrement x=5
    x--
    x=4

    Assignment Operators

    Operator Example Is The Same As
    = x=y x=y
    += x+=y x=x+y
    -= x-=y x=x-y
    *= x*=y x=x*y
    /= x/=y x=x/y
    .= x.=y x=x.y
    %= x%=y x=x%y

    Comparison Operators

    Operator Description Example
    == is equal to 5==8 returns false
    != is not equal 5!=8 returns true
    <> is not equal 5<>8 returns true
    > is greater than 5>8 returns false
    < is less than 5<8 returns true
    >= is greater than or equal to 5>=8 returns false
    <= is less than or equal to 5<=8 returns true

    Logical Operators

    Operator Description Example
    && and x=6
    y=3

    (x < 10 && y > 1) returns true

    || or x=6
    y=3

    (x==5 || y==5) returns false

    ! not x=6
    y=3

    !(x==y) returns true
