PHP loop patterns

Some patterns created with (nested) loops. Please comment if you have any.

Code:

for ($i = 0; $i < 10; $i++) {
    for ($j = 0; $j < 10; $j++) {
        if (in_array($j, [0, 9, $i]) || in_array($i, [0, 9, 9 - $j])) {
            echo "#";
        } else {
            echo ' ';
        }
    }
    echo "\n";
}

Output:

##########
##      ##
# #    # #
#  #  #  #
#   ##   #
#   ##   #
#  #  #  #
# #    # #
##      ##
##########

Not strictly a pattern , also not something I made. I saw this somewhere once, I just cant seem to remember where (If its yours, please inform me).

$i = 0;
while($i < 3) {
    printf("%c", 73 + $i * $i * 3);
    $i++;
}

This script prints ILU <3
