为数组中的每个值添加另一个参数[关闭]

Question

I have this code,

$values = array('a' => 'aa', 'b' => 'bb', 'c' => 'cc');
foreach ($values as $part1 => $part2) {
    echo $part1;
    echo $part2;
    }

How can I add another parameter to each value in the array, something like this?

$values = array('a' => 'aa' => 'aaa', 'b' => 'bb' => 'bbb', 'c' => 'cc' => 'ccc');
foreach ($values as $part1 => $part2 => $part3) {
    echo $part1; 
    echo $part2;
    echo $part3;
    }

Ty!;)

Not sure exactly what you're trying to do, but I think you're heading in the direction of having subarrays. Here's an example:

$values = array(
    'a' => 
        array( 'aa', 'aaa' ),
    'b' => 
        array( 'bb', 'bbb')
    //etc
);

var_dump($values);

Edit

To output, just have a two stage loop:

foreach($values as $k => $v) {
    echo($k . ':<br>'); // Will output the keys from above
    if(is_array($v)) {
        foreach($v as $i => $j)              // The value is an array, so iterate 
            echo(' &nbsp; ' . $j . '<br>');  // over all sub-elements 

    } else
        echo(' &nbsp; ' . $v . '<br>');
}
