Split results into variables after mysqli query - php

Question

I have following:
if($broj_podstanica != "" && $broj_podstanica != 0) {
$uzmi_podstanice = "SELECT * FROM objekt WHERE vrsta_objekta = '2' ORDER BY sifra ASC LIMIT $broj_podstanica";
$pronasao_sve_podstanice = $db->query($uzmi_podstanice);
while($sifrePodstanica = $pronasao_sve_podstanice->fetch_assoc()) {
$sifreIzbrojane = $sifrePodstanica['sifra'] . ",";
$izbaci_zarez = explode(",", $sifreIzbrojane);
if (!isset($izbaci_zarez[0])) {
$izbaci_zarez[0] = "";
$pods0 = "";
} else {
$pods0 = $izbaci_zarez[0];
}
if (!isset($izbaci_zarez[1])) {
$izbaci_zarez[1] = "";
$pods1 = "";
} else {
$pods1 = $izbaci_zarez[1];
}
if (!isset($izbaci_zarez[2])) {
$izbaci_zarez[2] = "";
$pods2 = "";
} else {
$pods2 = $izbaci_zarez[2];
}
}
echo "1:" . $pods0;
echo "2:" . $pods1;
echo "3:" . $pods2;
echo "4:" . $pods3;
echo "5:" . $pods4;
}
Query gives me results: 30313233.
After while loop I tried to control variables $pods0, $pods1, $pods2, $pods3 and $pods4 but It gives me result for first variable only; $pods0 is 30..
Is it possible to get other values from variables?

You have some problems with your code, first of all, you do not need use isset() function, it always returns true because of the variable is exists. Secondly, if $izbaci_zarez[1] is empty you do not need to set it again with an empty value. The last thing, store the data in an array instead of a variable and it will not limit your variables count (Because of it will hard to follow) and set the values to their correct index.
if($broj_podstanica != "" && $broj_podstanica != 0) {
$uzmi_podstanice = "SELECT * FROM objekt WHERE vrsta_objekta = '2' ORDER BY sifra ASC LIMIT $broj_podstanica";
$pronasao_sve_podstanice = $db->query($uzmi_podstanice);
$i = 1;
$pods = array();
while($sifrePodstanica = $pronasao_sve_podstanice->fetch_assoc()) {
$sifreIzbrojane = $sifrePodstanica['sifra'] . ",";
$izbaci_zarez = explode(",", $sifreIzbrojane);
$pods[$i] = $izbaci_zarez[0];
$i++;
}
echo "1:" . $pods[1];
echo "2:" . $pods[2];
echo "3:" . $pods[3];
echo "4:" . $pods[4];
echo "5:" . $pods[5];
// and etc...
}
