Subject: 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?
