What are the best practices for organizing arrays in PHP to avoid linking errors in search results?

When organizing arrays in PHP, it is important to ensure that keys are unique to avoid linking errors in search results. One way to achieve this is by using associative arrays with unique keys. This way, each element in the array can be easily accessed without the risk of overwriting or conflicting keys. 

// Example of organizing an array with unique keys
$students = array(
    "John" => array("age" => 20, "grade" => "A"),
    "Jane" => array("age" => 22, "grade" => "B"),
    "Alice" => array("age" => 21, "grade" => "C")
);
