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»'
),
'AU' => array (
'Description' => 'AUTHOR: (AU)',
'Input' => 'EricAU',
'Select' => 'SelAU',
'Option' => 'AU',
'Selected' => 'AU «Author»'
),
'TI' => array (
'Description' => 'TITLE: (TI)',
'Input' => 'EricTI',
'Select' => 'SelTI',
'Option' => 'TI',
'Selected' => 'TI «Title»'
),
'PY' => array (
'Description' => 'PUBLICATION_DATE: (PY)',
'Input' => 'EricPY',
'Select' => 'SelPY',
'Option' => 'YR',
'Selected' => 'YR «Year of Publication»'
),
24 more to go.
)
