What are some best practices for iterating through multidimensional arrays in PHP to access all entries efficiently?

Iterating through multidimensional arrays in PHP efficiently involves using nested loops to access all entries. One common approach is to use a combination of foreach loops for each dimension of the array. This allows for easy traversal through the array elements and accessing their values. 

// Example of iterating through a multidimensional array efficiently
$multiArray = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
];

foreach ($multiArray as $innerArray) {
    foreach ($innerArray as $value) {
        echo $value . " ";
    }
}
