Operators in PHP

Operators are used to perform operations on variables and values. PHP supports various types of operators.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations:

      
        <?php
          $x = 10;
          $y = 5;
          echo $x + $y; // Addition
          echo $x - $y; // Subtraction
          echo $x * $y; // Multiplication
          echo $x / $y; // Division
        ?>

Comparison Operators

Comparison operators are used to compare values:

      
        <?php
          $x = 10;
          $y = 5;
          echo $x == $y; // Equal to
          echo $x != $y; // Not equal to
          echo $x > $y; // Greater than
        ?>
