Using loop to create a shape - php

Question

I'm supposed to use nested for loops to create this shape: https://imgur.com/a/prh6zwj
This is what I currently have:
<?php
for ($x = 1; $x <= 10; $x++){
for ($y = 1; $y <= 6; $y++){
echo "Y";
}
}
?>
I have no clue what to do.
Thanks in advance!

Answer 1

<?php
$position = 1;
for ($x = 1; $x <= 11; $x++){
for ($y = 1; $y <= 6; $y++){
if ($y == $position) {
echo "Y";
} else {
echo "0";
}
}
if ($x < 6) {
$position++;
} else {
$position--;
}
echo "\n";
}

Answer 2

<?php
$length = 6; // change this to change height width
$pos = 0;
for ($x = 1; $x <= (($length*2)-1); $x++){
if($x <= $length)
{$pos = $pos+1; }
else
{$pos = $pos-1; }
for ($y = 1; $y <= $length; $y++){
if($y == $pos)
echo "Y";
else
echo "O";
}
echo "\n";
}

Answer 3

There are many possible ways to achieve this when I started programming I never cared about the code quality and just focused on the output. I have added two examples to help you understand it better!
<?php
//We have 6 columns & 11 rows so we need two loops one size of 11 and second size of 6
$counter = 1;
for ($i = 1; $i <= 11; $i++){
for ($j = 1; $j <= 6; $j++){
if ($j == $counter) {
echo "Y";
} else {
echo "O";
}
}
if ($i < 6) {
$counter++;
} else {
$counter--;
}
echo "<br/>";
}
echo "**************************** METHOD TWO ****************************";
//Following is not efficient But its also printing the same results
for ($i = 0 ; $i < 66 ; $i++){
if($i == 65)
{
echo "O";
break;
}
if($i % 6 == 0){
echo "<br/>";
}
if($i <= 36)
{
if ($i % 7 == 0){
echo "Y";
}else{
echo "O";
}
}else{
if ($i % 5 == 0){
echo "Y";
}else{
echo "O";
}
}
}
?>

Answer 4

$k=2; // for calculating position from backside
for($i=1;$i<=11;$i++) //for row
{
for($j=1;$j<=6;$j++) //column
{
if($j==$i && $i<=6) //logic for printing "Y" till the end of row
echo "Y";
else if($i>6 && $j==($i-$k)) //logic for printing "Y" in reversal order from the end of row
{
echo "Y";
$k+=2;
}
else
echo "O"; // filling rest places with "O"
}
echo"\n"; // jumping to new Row;
}
Hope you can understand it easily.
