Question

I am trying to make a program that gives an oputput like:

x

xx

xxx

xxxx

xxxxx

xxxx

xxx

xx

x

I have a similar program which is:

<?php
    $n = 4;                                     
    $R[] = '*';                                  
    $w = 1;                                     
        for( $c=1; $c<=$n; $c++ ){             
            $R[] = '*'.str_repeat( '*',$w );  
            $w = $w+1;                       
        }        
    print '<pre>'.implode( "\n",$R ).'</pre>';  
?>

but i need to use a function and create an other loop for an easier code.
I also need to decrease it after 5th row.
thanx in advance…

<?php
function drawPyramid($length) {
    for ($i = 1; $i <= $length; ++$i) {
        echo str_repeat("x", $i) . "\n";
    }
    for ($i = $length - 1; $i > 0; --$i) {
        echo str_repeat("x", $i) . "\n";
    }
}

drawPyramid(3);
echo "\n";
drawPyramid(5);
