Arrays in PHP

Arrays in PHP are used to store multiple values in a single variable. PHP supports both indexed arrays and associative arrays.

Indexed Arrays

An indexed array stores values with a numeric index:

      
        <?php
          $fruits = array("Apple", "Banana", "Cherry");
          echo $fruits[0]; // Outputs Apple
        ?>

Associative Arrays

Associative arrays use named keys to store values:

      
        <?php
          $person = array("name" => "John", "age" => 30);
          echo $person["name"]; // Outputs John
        ?>
