So the app should read from database if condition is met and print on page in this format:
here are codes and i will post image of my output in the end
lib.php:
<?php
$db_name = "ispit_septembar";
$db_user = "root";

$db_pass = "";
function vratiStudente($godina)

$link = mysql_connect("$db_host","$db_user","$db_pass") or die ("Nije moguca konekcija");
mysql_select_db("$db_name",$link) or die ("Nepostojeca baza");
$sql = mysql_query("SELECT * from studenti where godina = '$godina'");
while ($row = mysql_fetch_array($sql) )
{

$sql = mysql_query("SELECT * from studenti where indeks = '$indeks'");
$check = mysql_num_rows($sql);
if ($check >0 )
{
$postoji = "postoji";
}
else
{

}
return $postoji;

this is my_sql base structure:
and my output (Wrong one):
and now, questions:
I can’t figure out why first member of frist array ($studenty1) as attributes index,imeiprezime and godina has indeks,3,3 – it should be 12345,dusan skoric, 1.
And second question, why is last indeks attribute from last member of first array used as ideks attribute for every member of next two arrays(Studenti2,studenti3)
ok, i’ve solved my first question:
line studenti[“indeks”] = $indeks in lib.php was making problems, but still cant find answer to second question
