 My objective was to try and NOT use a temporary variable.
 
 for example I can do this:
 
 foreach ($res_pform-getSubmitValue(investigator5) AS $k=$v){
   echo $k . br;
 }
 
 I was just wondering in other circumstances, how I can maybe just get 
 to the value of one of the keys without setting it first to a 
 variable 

Sorry, but you can't -- the intermediate variable is the only way (because you can 
only apply [] to variables!).

Cheers!

Mike

You can try:

 list($field1, $field2, ...) = $res_pform-getSubmitValue(investigator5);

I was just wondering in other circumstances, how I can maybe just get

(which is the only way I know how to now).

Thanks,

Have you tried:

extract ($myvar = $res_pform-getSubmitValue(investigator5));

hi there,

if this:

$res_pform-getSubmitValue(investigator5);

returns an array, how do I get to the individual values in that array
without first setting it to a variable like:
$myvar = $res_pform-getSubmitValue(investigator5);

echo $myvar['field'];

thanks
charles
