Php: problem with associative arrays

If i have an array with hundreds of random ids (having values too) like

(3=>23,2=>34,17=>670,5=>67...)

how can i get an output like following via a loop

ID: 3 has a value= 23
ID: 2 has a value= 34
ID: 17 has a value= 670
ID: 5 has a value= 67

I can reference the values by their IDs like

  echo $myArray['3'];

but what if don't know in advance that what the next ID is? I mean how can i reference the IDs automatically with a loop? Is it even possible to code the following pseudo code in php?

myArray's first location's ID has value = $myArray[$myArray's first location item]
myArray's 2nd location's ID has value = $myArray[$myArray's 2nd location item]

Need help plz...

Why not just:

foreach ($myArray as $k => $v) {
  echo "ID: $k has a value= $v\n";
}

?
