[RESOLVED] Finding Array Values from Another Array

[Cent]

Hi All,

Been trying to figure this out. I have 2 arrays. The first has a number of keys and values. The 2nd just has the keys. I want to use the 2nd array to return the appropriate values from the 1st array based on the key.

$salespeople = array {
       0=>"Everyone", 
	1=>"Bob", 
	2=>"Mary",
	3=>"Sam",
	4=>"Linda",
	5=>"Peter",
	6=>"John");

$newvalues = "1|3|5";   # stored in DB like this
$savedArray = explode("|", $newvalues);

So I want to compare the savedArray and the salespeople and get back Bob, Sam and Peter.

I was thinking of counting the number of items in savedArray and then doing for loop such as:

$count = count($savedArray);
for ($i = 0; $i <= $count - 1; $i++) 
{
     echo $salespeople[$savedArray[$i]];
}

Is there a more efficient way of doing this?

Thanks in advance,
Cent

maybe

foreach($savedArray as $index) {
  echo $salespeople[$index];
}

few less lines anyway

Ah... that's what I needed. Thanks!
