How to Extract Specific Column Values (filepath and filename) from a Multidimensional Array in PHP?

Retrieving Specific Column Values from a Multidimensional Array

Given a multidimensional array, the task is to extract and display specific column values (filepath and filename) for each row.

Looping Strategies

There are several looping techniques available for navigating multidimensional arrays:

Foreach Loop without Key:

foreach ($array as $item) {
    echo $item['filename'];
    echo $item['filepath'];
}

This iterates through each row in the array, treating it as its own array and accessing individual columns using the corresponding keys.

Foreach Loop with Key:

foreach ($array as $i => $item) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

Similar to the previous method, but it additionally provides the row index in the $i variable.

For Loop:

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

This uses a traditional for loop to iterate through the array's rows directly.
