Lets not do it Mr Benson's way OK!
I'm sure if I had to draw a 10x10 grid on paper I wouldn't do it by drawing 100 individual squares, redrawing nearly half of the lines twice.
I'd probably do it by drawing 11 vertical lines and 11 horizontal lines.
function ImageGrid2(&$im,$startx,$starty,$width,$height,$xcols,$yrows,&$color) {
$endy = $starty + $height * $yrows;
for ( $x=0; $x <= $xcols; $x++ ) {
$x1 = $startx + $width * $x;
imageline ( $im, $x1, $starty, $x1, $endy, $color );
}
$endx = $startx + $width * $xcols;
for ( $y=0; $y <= $yrows; $y++ ) {
$y1 = $starty + $height * $y;
imageline ( $im, $startx, $y1, $endx, $y1, $color );
}
}

If you want an empty rectangle, I mean, just the borders, fill it first with the ImageFilledRectangle function with the background color and then draw it with this function.

For those wanting a function to draw a grid I've created one. I hope this is the right place to post it.
function ImageGrid(&$im,$startx,$starty,$width,$height,$xcols,$yrows,&$color) {
for ( $x=0; $x < $xcols; $x++ ) {
for ( $y=0; $y < $yrows; $y++ ) {
$x1 = $startx + ($width * $x);
$x2 = $startx + ($width * ($x+1));
$y1 = $starty + ($height * $y);
$y2 = $starty + ($height * ($y+1));
ImageRectangle($im, $x1, $y1, $x2, $y2, $color);
}
}
} // end function ImageGrid
