Answer 1

The problem is your SQL statement is giving the equation 5-1 as a value, so the server is doing the math and inserting 4 just like you told it to. You need tell it that it's a literal string by surrounding the values with apostrophe's (i.e. '5-1').
Replace:
foreach ($input AS $key => $value) {
$i = $i + 1;
if ($i !== count($input)) {
$a = ', ';
} else {
$a = '';
}
$velden .= $key . $a;
$waarden .= $value . $a;
unset($a);
}
With:
$velden = array();
$waarden = array();
foreach ($input AS $key => $value) {
$velden[] = $key;
$waarden[] = $value;
}
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
Or possibly even:
$velden = array_keys($input);
$waarden = array_values($input);
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
