In PHP, how do I index arrays with examples?

In PHP, you can index arrays using both numeric and associative keys. Here's a brief overview of each type along with examples:

Numeric Indexing

Numeric arrays use sequential integer keys to access their values. Here’s how you can create and index a numeric array:

// Create a numeric array $fruits = array('Apple', 'Banana', 'Cherry'); // Access array elements echo $fruits[0]; // Outputs: Apple echo $fruits[1]; // Outputs: Banana echo $fruits[2]; // Outputs: Cherry

Associative Indexing

Associative arrays use named keys that you assign to them. Here’s an example of creating and indexing an associative array:

// Create an associative array $ages = array('Alice' => 25, 'Bob' => 30, 'Charlie' => 35); // Access array elements using keys echo $ages['Alice']; // Outputs: 25 echo $ages['Bob']; // Outputs: 30 echo $ages['Charlie']; // Outputs: 35

Conclusion

Indexing arrays in PHP is straightforward with numeric and associative types available for your needs.
