How to Efficiently Extract Specific Column Values from a Multidimensional Array in PHP?

Looping through a Multidimensional Array and Printing Specific Column Values

Multidimensional arrays are a common data structure used to organize complex data in PHP. When working with these arrays, you may need to extract specific information from each row. Suppose you have an array containing files with the following columns:

• filepath
• filename

The goal is to print only these two values from each row. Here are three approaches to achieve this:

1. Foreach Loop without a Key:

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

2. Foreach Loop with a Key:

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

3. For Loop:

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

Utilizing var_dump for Debugging:

Regardless of the approach you choose, using var_dump() on $item can provide valuable insights into the structure and contents of the array. By printing the output of var_dump() within a loop, you can identify and resolve any discrepancies or data issues.
