Array for each question

Hello,

I am confused.

I made the following array and thought it would 'foreach' like I wrote it, but obviously I am very wrong.

Can you please help me fix it.

$hemdetails = array (
    "make"  => array("bmw", "bmw", "bmw", "bmw", "bmw"),
    "model"  => array("1600", "1602", "2002", "2002ti", "2002tii"),
    "minyear" => array("1960", "1960", "1960", "1960", "1960"),
    "maxyear"   => array("1980", "1980", "1980", "1980", "1980" )
);

$hemcollection[] = '';

foreach($hemdetails as $details){
      echo $details['make'].' '.$details['model'].' '.$details['minyear'].' '.$details['maxyear'];
}

"make"  => array("bmw", "bmw", "bmw", "bmw", "bmw"), will create a numbered array starting with 0.  You could access it with a 'for' loop.
for ($i = 0; $i <= 5; $i++) {
    echo $hemdetails['make'][$i].' '.$hemdetails['model'][$i].' '.$hemdetails['minyear'][$i].' '.$hemdetails['maxyear'][$i];
}

You might want to learn about the idea of an array of objects.  You have all the same capabilities that you get with an array of arrays, but the syntax is easier to get right since you don't have all the fiddly quote marks.  And if you write your own class definitions you can have your own programming automatically applied to your data as you create or modify the objects.  Just a thought... ~Ray
