need help printing from foreach loop

[shivers3000]

Can some1 briefly explain what's going on? Why the entire $intAutoOptions wont print outside the foreach()? Within the foreach(), I take each value and and a comma + a space. If I print the $intAutoOptions from the foreach(), it prints fine. If I print it from outside it on prints the values and not the commas or the spaces. What's am I doing wrong?

if ($intAutoOptionsArray == 'null')
$intAutoOptions = "Please contact seller for vehicle options";
else
{ $commaLimit = -1;
$commaCounter = 1;
foreach($intAutoOptionsArray as $key => $value)
{
$commaLimit++;
}
foreach($intAutoOptionsArray as $key => $value)
{
$value = getdefinitions( 'definitionoptions', 'intAutoOptID' , $value);
$intAutoOptions = $value;
if ($commaCounter <= $commaLimit)
$intAutoOptions = $intAutoOptions.",&nbsp;";

//==>Here is the problem if I print $intAutoOptions from here is shows with the appropriate commas and spaces

$commaCounter++;
}
//==>If I print from outside the foreach() it only shows the values minus the spaces and commas
echo $intAutoOptions;
}

$intAutoOptions = $value;
if ($commaCounter <= $commaLimit)
$intAutoOptions = $intAutoOptions.", ";

Looks to me that you're just overwriting the value instead of creating a string. Using .= instead of just = will add it to the sttring. Also, I don't really know what you're doing with getdefinitions(), but you might be able to just do this with one call to [man]implode[/man]

It has to be something other than that. Because the values from the array are being added to the variable and not replacing them.
example:
$intAutoOptions = $intAutoOptions.$value

It prints the above line out fine outside of the foreach loop. But it wont print out the

$intAutoOptions = $intAutoOptions.",&nbsp;":

line unless its within the loop. If I try to print it outside of the loop it prints all of the values correctly but not the spaces and commas.

Print out from within the loop:$intAutoOptions
a/c, air bags, cd player, moon roof

Print out from outside the loop:$intAutoOptions
a/cair bagscd playermoon roof

Also, the getdefinitions() is how I retrieve the appropriate autoOption from the database
