What are some best practices for structuring and accessing multi-dimensional arrays in PHP?

When working with multi-dimensional arrays in PHP, it is important to have a clear structure and use proper indexing to access the elements efficiently. One best practice is to use nested loops to iterate through the array and access the values based on the specified keys. 

// Example of structuring and accessing a multi-dimensional array in PHP

// Define a multi-dimensional array
$multiArray = array(
    array("John", "Doe", 30),
    array("Jane", "Smith", 25),
    array("Tom", "Jones", 35)
);

// Accessing elements using nested loops
foreach ($multiArray as $innerArray) {
    foreach ($innerArray as $value) {
        echo $value . " ";
    }
    echo "<br>";
}
