使用一个foreach获取数组中的数组值

Question

I want to get the values of an array inside an array but I couldn't make it work. This is what I tried.

for($i=2;$i<=$row_count;$i++){
    $auto_part = 'auto_part'.$i;
    $auto_parts['part'][] = $_POST[$auto_part];
    $description = 'auto_description'.$i;
    $auto_parts['description'][] = $_POST[$description];
}
foreach($auto_parts as $part){
    echo $part['part'];
    echo $part['description'];
}

The for loop is right and the array is build up the way I want too I checked that. But how can I get both arrays of $part['part'] and $part['description'] in one foreach?

Answer 1

Structure your array differently if the data is related

for($i=2; $i<=$row_count; $i++){
    $auto_part = 'auto_part' . $i;
    $description = 'auto_description' . $i;
    $auto_parts[] = array(
        'part' => $_POST[$auto_part],
        'description' => $_POST[$description]
    );
}
foreach($auto_parts as $part){
    echo $part['part'];
    echo $part['description'];
}
