PHP has a variety of operators that can be used in different types of expressions. Here are some examples of common operators in PHP:
Arithmetic operators
Arithmetic operators are used to perform basic arithmetic operations on numerical values.
+: addition-: subtraction*: multiplication/: division%: modulus (remainder after division)
$x = 10;
$y = 5;
echo $x + $y; // 15
echo $x - $y; // 5
echo $x * $y; // 50
echo $x / $y; // 2
echo $x % $y; // 0
Assignment operators
Assignment operators are used to assign a value to a variable.
=: assignment+=: addition assignment-=: subtraction assignment*=: multiplication assignment/=: division assignment%=: modulus assignment
$x = 10;
$y = 5;
$x += $y; // $x is now 15
$x -= $y; // $x is now 10
$x *= $y; // $x is now 50
$x /= $y; // $x is now 10
$x %= $y; // $x is now 0
Comparison operators
Comparison operators are used to compare two values and return a Boolean result.
==: equal to!=: not equal to>: greater than<: less than>=: greater than or equal to<=: less than or equal to
$x = 10;
$y = 5;
echo $x == $y; // false
echo $x != $y; // true
echo $x > $y; // true
echo $x < $y; // false
echo $x >= $y; // true
echo $x <= $y; // false
Logical operators
Logical operators are used to perform logical operations on Boolean values.
&&: and||: or!: not
$x = true;
$y = false;
echo $x && $y; // false
echo $x || $y; // true
echo !$x; // false
These are just a few examples of the operators available in PHP. There are many other operators that can be used for different purposes, such as the ternary operator (? :) for conditional expressions, the bitwise operators for working with binary data, and the type operators for checking the type of a value.
