Looks like you have a scope issue :
$a = 'foo';
function bar()
{
$a = 'bar';
}
bar();
print $a; // prints foo
outside of the function, $a has not been affected. want it to be? then
try something like :
$a = 'foo';
function bar()
{
global $a;
$a = 'bar';
}
bar();
print $a; // prints bar
see how that works? now if you're just wanting to get a row count then
try something like :
function getRowCount($table)
{
$r = mysql_query("SELECT count(*) FROM $table");
return mysql_result($r,0);
}
print getRowCount('tablename');
it's much faster to rely on sql count function as opposed to selecting all
data and using x_num_rows. regarding functions and scope, see :
