hai,
this is my sample code:
i am having user table with SponsorID as one field in
mysql database,this is my query;
for($j=0;$j<5;$j++):
$result=mysql_query("select * from user where SponsorID='$id[$j]' ");
endfor;
in above code when i print mysql_num_rows($result) inside for loop its output is 5.when i print outside the for loop its o/p is 0.I searched weberdev.com website and declared $result as global.but same output 0.i want $result variable to be available outsibe the forloop and all other part of my code.i am looking forward suggestions from ur side.

At first i would rather use the LIMIT from MySQL than a for loop.
$query = "SELECT * FROM foo WHERE bar = 'foobar' LIMIT 5";
$result = mysql_query($query);
// Now you can use a while loop to print it out
while ($row = mysql_fetch_assoc($result))
// mysql_fetch_assoc is the same as mysql_fetch_array with ASSOC
{
echo $row["somefield"];
// to have it availible out of the code use this
$outer_array[] = $row;
}
print_r($outer_array);
// now the array has the fields of the Query in it.
// as you can see using print_r();
// now you can access it like:
$outer_array[0];
$outer_array[1];
...
$outer_array[n];
Your FOR loop replaces the variable $result everytime.
That's why it is empty.
