guys! I'm in trouble with my MySQL database. When I try to access the fields it doesn't return the exact value. Here is the code.
<?php
$host = "localhost";
$user = "******";
$pass = "******";
$db = mysql_connect($host, $user, $pass) or die("Unable to connect. Check your connection parameters.");
mysql_select_db("*****") or die("Unable to select database!");
$form_username=$_POST["username"];
$form_password=$_POST["password"];
$query="
SELECT username, password FROM users
";
$result=mysql_query($query,$db) or die("Unable to send the query".mysql_error());
$index=0;
while($row=mysql_fetch_row($result))
{
$username[$index]=row[0];
$password[$index]=row[1];
$index++;
}
for($i=0; $i<=$index; $i++)
{
if($form_username==$username[$i]&& $form_password==$password[$i])
{
session_start();
$_SESSION["login"]="OK";
header("Location: ************");
die();
}
}
The if statement inside the for operator returns false for every given value. When I echo every username and password like this:
echo $form_username." ".$username[0]." ".$form_password." ".$password[0]."<br>";
echo $form_username." ".$username[1]." ".$form_password." ".$password[1]."<br>";
echo $form_username." ".$username[2]." ".$form_password." ".$password[2]."<br>";
It echo me this:
admin r 12345 o
admin r 12345 o
admin r 12345 o
I really don't know where the problem is.
I'll really appreciate your help.

Should this bit:
while($row=mysql_fetch_row($result))
{
$username[$index]=row[0];
$password[$index]=row[1];
$index++;
}
Read:
while($row=mysql_fetch_row($result))
{
$username[$index] = $row[0];
$password[$index] = $row[1];
$index++;
}
Note missing $ on the variable names.
