Question

I have the following code

while($row = $usafisRSP->fetch_assoc()) {
    $id = $row['id'];
    $Applicantid = $row['Applicantid'];
    $unique_num = $row['unique_num'];

    // .................

    $hidden_fields = array($Applicantid, $unique_num, $regs_t ....);
    $hidden_values = array();

   foreach ($hidden_fields as $key => $value) {
       $hidden_values[$value] = "$key = ".base64_decode($value)."<br>";
       echo $hidden_values[$value];
   }
}

and the result is something like this

0 = 116153840
1 = 136676636
2 = 2010-12-17T04:12:37.077
3 = XQ376
4 = MUKANTABANA

I would like to replace 0, 1, 2, 3 etc with some custom values like “Id”, “application name” to make the result like

id = 116153840
application name = 136676636
etc ..

how can I do that ?

Replace the $hidden_fields = array(... line with the following:

$hidden_keys = array('id', 'Applicantid', 'unique_num');
$hidden_fields = array_intersect_key($row, array_fill_keys($hidden_keys, NULL));

If you want to suppress all fields with value 0, either use

$hidden_fields = array_filter($hidden_fields, function($v) {return $v != 0;});

(this will completely omit the 0-entries) or

$hidden_fields = array_map($hidden_fields, function($v) {return ($v==0?'':$v);});

(this will leave them blank). If you’re using an older version than 5.3, you’ll have to replace the anonymous functions with calls to create_function.
