I am working through PHP, MySQL & Apache trying to learn how to program in PHP more fluidly. Im in the nested loops section and am working on this chunck of code.
<?php
echo "<table border=\"1\" cellpadding=\"4\" cellspacing=\"4\"> \n";
for ($y=1; $y<=12; $y++) {
echo "<tr> \n";
for ($y=1; $y<=12; $y++) {
echo "<td>";
echo ($x * $y);
echo "</td> \n";
}
echo "</tr> \n";
}
echo "</table>";
?>
This is supposed to display a multiplication chart from 1-12 both vertically & horizontally. But when I upload it to my server i get this... 0 0 0 0 0 0 0 0 0 0 0 0
I am running PHP Version 4.3.10 & Apache/2.0.51 (Fedora).
I would appreciate any help you guys can give on this, thanks :)

If it's mostly syntax you need, then you probalby couldn't really go wrong with the PHP manual that's online: http://us3.php.net/manual/
There's also a tutorial from the w3schools site, most of those are fairly good for introductory stuff: http://www.w3schools.com/p
Hope that helps.

You used the same varialbe twice ... both inner & outer loops were iterating through $y. I changed the outer one to use $x, hope that helps.
<?php
echo "<table border=\"1\" cellpadding=\"4\" cellspacing=\"4\"> \n";
for ($x=1; $x<=12; $x++) {
echo "<tr> \n";
for ($y=1; $y<=12; $y++) {
echo "<td>";
echo ($x * $y);
echo "</td> \n";
}
echo "</tr> \n";
}
echo "</table>";
?>
