Question

I have a form and I have many values. When I am trying the save these values to the MySQL, it doesn’t save the zero values which are coming from form.
Here is my codes.

for($i=0;$i<count($cevap_deger);$i++){
  $cevapkontrol = trim($cevap_deger[$i]);
  if(!empty($cevapkontrol)){
    $sorgu = mysql_query("insert into CRM9001(CRM9107,CRM9102,CRM9103,CRM9105,CRM9109,CRM9108) values ('".$cevap_deger[$i]."','".$sinav_id[$i]."','".$bolum_id[$i]."','".$soru_id[$i]."','".$birey_id[$i]."','".$kullanici_id[$i]."') ");
    header("Refresh: 0; url=dashboard.php");
  }
}

It saves other values but only 0 it doesn’t save. I tried this also;

for($i=0;$i<=count($cevap_deger);$i++){

If you help me I will be very glad.

php.net says:

The following things are considered to be empty:

"" (an empty string)
0 (0 as an integer)
0.0 (0 as a float)
"0" (0 as a string)
NULL
FALSE
array() (an empty array)
$var; (a variable declared, but without a value)

note that you insert data into the database only if $cevapkontrol is not empty as in if(!empty($cevapkontrol)){} and 0 considered to be empty as mentioned
