Re: More array syntax

Hi John, foreach ($var as $key => $value) {

    if (!$key) {
         $$key = filter_string($key.': ',$line);
    }

I have an array $var (see structure below), which contains AN, AU, TI, PY ... etc. (28 in total - no teasing.) How can access these keys so I can do this: foreach key in $var until $var.length { if(!$something){$something = filter_strings("something: ",$line);} } So I can avoid doing this 28 times: if(!$AN){$AN = filter_strings("AN: ",$line);} if(!$AU){$AU = filter_strings("AU: ",$line);} if(!$TI){$TI = filter_strings("TI: ",$line);} if(!$PY){$PY = filter_strings("PY: ",$line);} ... and this 28 times. if($AN) {DisplayLine('AN',$AN);} if($AU) {DisplayLine('AU',$AU);} if($TI) {DisplayLine('TI',$TI);} if($PY) {DisplayLine('PY',$PY);} ... $var = array ( 'AN' => array ( 'Description' => 'ERIC_NO: (AN)',

 'Input'       => 'EricAN',
 'Select'      => 'SelAN',
 'Option'      => 'AN',
 'Selected'    => 'AN «Annotation»'

 'Selected'    => 'YR «Year of Publication»'

), 24 more to go. )
