Re: Creating variable names from values

From an arry I create a table like foreach ($persons as $key => $pers) {

    echo "<td><input name=\"K$key\" type=\"checkbox\" ...></td>
          <td>...</td>

} so each checkbox field has its own name created from $key. Yet how can I access these fields (names) later on? foreach ($persons as $key => $pers) {

$key = 'K' . $key; if ($$key) { notice double dollar sign, it means, not the value of $key but the value of the variable $key says.

    if ($K???) {
      $cnt += 1; ...
    }

} Is there a better way to access multiple fields from a table? O.
