white space on echo " ";

Do not want to correct the code I want why echo " "; is not printed in my pyramid shape of *?

$x = 7;
for($i=1;$i<=$x;$i++){
    for($j=1; $j<=$x-$i; ++$j) {
        echo " ";
    }
    for($k=1; $k<=$i; ++$k) {
        echo "* ";
    }
    echo "<br>";
}

>Solution :

You can enclose your code in <pre> tags to display multiple spaces in the browser. We recommend using "\n" instead of <br>.

echo '<pre>'; 
$x = 7;
for($i=1;$i<=$x;$i++){
    for($j=1; $j<=$x-$i; ++$j) {
        echo " ";
    }
    for($k=1; $k<=$i; ++$k) {
        echo "* ";
    }
    echo "\r\n";
}
echo '</pre>';

Alternatively, a special header can also be set with PHP.

header('Content-Type: text/plain');
