- Assignment operators
- Increment/Decrement operators
- Arithmetic operators
- Comparison operators
- Logical operators
- Array operators
- String operators
ArithMetic Operators Types | Example
Let us understand few of them with examples-There are six following arithmetic operators in php. Following table is an example which easily describes all arithmetic operators in brief.
| Operator Symbol | Name | Example | Meaning |
|---|---|---|---|
| – | Substraction | $x-$y | Difference of two numbers |
| * | Multiplication | $x*$y | Multiplication of two numbers |
| / | Division | $x*$y | Division of two numbers |
| % | Modulus | $x%$y | Modulus of two numbers |
| ** | Exponentiation | $x**$y | EResult after raising $x to the $y’th power |
| * | Multiplication | $x*$y | Multiplication of two numbers |
Comparison Operators Types | Example
These operators are used to compare values. Below table represents their usage in php.
| Operator Symbol | Name | Example | Meaning |
|---|---|---|---|
| != | Not equal | $a != $b | Returns true if $x is not equal to $y |
| <> | Not equal | $a<>$b | Returns true if $x is not equal to $y |
| !== | Not identical | a!==$b | True if $x is not equal to $y, or they are not of the same type |
| === | Identical | $a===$b | Returns true if $x is equal to $y, and they are of the same type |
| == | Equal | $a==$b | Returns true if $x is equal to $y |
| > | Greater than | $a>$b | eturns true if $x is greater than $y |
| < | Less than | $a<<$b | Returns true if $x is less than $y |
| <= | Less than or equal to | $a<=$b | Returns true if $x is less than or equal to $y |
| >= | Greater than or equal to | $a>=$b | Returns true if $x is greater than or equal to $y |
