mysql_fetch_array Not working at all

Hi,
I have this strange problem, I select some data from the database, there is no problem in the query and even when I use mysql_num_rows on the query it gives me the right number of entries in the table I'm selecting from, but when I try to echo every row it echos empty values... what is the problem??

PHP Syntax (Toggle Plain Text) 
  1. $sql = "SELECT * FROM table";
  2. 		$query = mysql_query($sql) or die(mysql_error());
  3. 		$row_number = mysql_num_rows($query);
  4. 		while ($row = mysql_fetch_array($query))
  5. 		{
  6. 			echo "row= ".$row["id"];
  7.                          }

Try changing "$row['id']" to "$row[0]" and see if you still get nothing.
$me = new Person();
if (isset($_COOKIE)){
$me->eat($_COOKIE);
} else { $me->starve(); }

I solved it in a really strange way guys.. wtf is this version of PHP that i'm using, that obliges me to declare the variables before using.

I just put $row=0; $search_row=0; before making the query and it worked, really strange!!!!

thanks anyway

Thats good you solved it. But this $row is an array. So making it 0 is a bit strange. What other thing you can do is, you can declare it as an empty array:

php Syntax (Toggle Plain Text) 
  1. $row = array();
  2.  
  3. $row = mysql_fetch_array();
  4. // Proceed with rest of the code
VâRûN

Yes I used some arrays in my script and had to declare some of the variable as $variable = array();
