In PHP, indexing arrays is essential for retrieving and manipulating the data they hold. Arrays can be indexed numerically or with string keys. Here’s a simple guide on how to index arrays for beginners.
Numeric indexed arrays use integers as keys. You can create an array and access its elements using their respective indices.
Associative arrays use named keys that you assign to them. This is useful for keeping track of specific data related to the keys.
"John Doe",
"age" => 30,
"email" => "john@example.com"
);
// Access the 'name' key
echo $person["name"]; // Outputs: John Doe
?>
Multi-dimensional arrays are arrays containing one or more arrays. You can think of them as arrays within arrays.
These examples should help you understand how to index arrays in PHP. Happy coding!
