Are there any specific PHP functions that can streamline the process of extracting values from arrays returned by custom functions like coll()?

When extracting values from arrays returned by custom functions like coll(), you can streamline the process by using PHP's array_column() function. This function allows you to extract values from a multidimensional array based on a specific key. By specifying the key you want to extract, array_column() simplifies the process of retrieving values from nested arrays returned by custom functions. 

// Example of using array_column() to extract values from arrays returned by custom functions like coll()

// Custom function coll() returns a multidimensional array
function coll() {
    return [
        ['id' => 1, 'name' => 'Alice'],
        ['id' => 2, 'name' => 'Bob'],
        ['id' => 3, 'name' => 'Charlie']
    ];
}

// Extracting names from the array returned by coll()
$names = array_column(coll(), 'name');

// Output the extracted names
print_r($names);
