Displaying contents of array (using PHP foreach?)

I'm working on a WordPress site and am using a plugin called 'Simple Fields', to add data to repeatable fields. I've entered data into three fields: (audioinfo, audiofile, audiocomposer).

I would now like to create a post that displays that information in the following way:

Audio Info 1

Audio File 1

Audio Composer 1

~~~

Audio Info 2

Audio File 2

Audio Composer 2

I've been trying to figure this out with foreach. Here's the closest I can arrive at (thought I know it's invalid). Can anyone make any suggestions of how to handle this?

<?php 
$audioinfo = simple_fields_values("audioinfo");
$audiofile = simple_fields_values("audiofile");
$audiocomposer = simple_fields_values("audiocomposer") 
foreach ($audioinfo as $audioinfos, $audiofile as $audiofiles, $audiocomposer as $audiocomposers){
echo $audioinfos;
echo $audiofile;
echo $audiocomposer;
}
?>

(Just as a side note, in case it's important, the first three lines appear to all be valid - that is, if I do a "foreach" on $audiocomposer alone, I successfully get: Bach Handel Beethoven.)

Is there something I can do to apply "foreach" to all three at the same time?

Thanks!

Assuming there are always going to be the same number of items in all 3 arrays, you could do something like this:

$items = count($audioinfo);
for ($i = 0; $i < $items; $i++)
{
    echo $audioinfo[$i];
    echo $audiofile[$i];
    echo $audiocomposer[$i];
}

Assuming all the arrays of same length, making use of a normal for loop.

<?php 
$audioinfo = simple_fields_values("audioinfo");
$audiofile = simple_fields_values("audiofile");
$audiocomposer = simple_fields_values("audiocomposer");

for($i=0;$i<count($audioinfo);$i++)
{
echo $audioinfo[$i];
echo $audiofile[$i];
echo $audiocomposer[$i];
}
?>

One more pretty solution:

<?php 
$audioinfo = simple_fields_values("audioinfo");
$audiofile = simple_fields_values("audiofile");
$audiocomposer = simple_fields_values("audiocomposer");

foreach ($audioinfo as $k => $val){
  echo $val;
  echo $audiofile[$k];
  echo $audiocomposer[$k];
}
?>
