PHP Operators
This section lists the different operators used in PHP.
Arithmetic Operators
OperatorDescriptionExampleResult
+ | 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
OperatorExampleIs 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
OperatorDescriptionExample
== | is equal to | 5==8 returns false |
!= | 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
OperatorDescriptionExample
&& | 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 |
