 직각 삼각형

$max = 5;

for ($n1 = 0; $n1 <= $max; $n1++) 
{
    for ($n2 = 0; $n2 < $n1 ; $n2++) { 
        echo "*";
    }
    echo "*\n";
}

 직각 삼각형 반대쪽으로 붙이기

$max = 5;

for ($n1 = 0; $n1 <= $max; $n1++) 
{
    for ($blank = $max - $n1; $blank > 0 ; $blank--) { 
        echo " ";
    }
    for ($n2 = 0; $n2 < $n1 ; $n2++) { 
        echo "*";
    }
    echo "\n";
}

 직각 삼각형 뒤집기

$max = 5;

for ($n1 = 0; $n1 <= $max; $n1++) 
{
    for ($n2 = 0; $n2 <= $max - $n1; $n2++) 
    { 
        echo "*";
    }
    echo "\n";
}

 피라미드

$max = 5;

for ($n1 = 0; $n1 <= $max; $n1++)
{ 
    for ($blank = $max - $n1; $blank > 0; $blank--)
    { 
        echo " ";
    }
    for ($n2 = 0; $n2 <= $n1; $n2++) 
    { 
        echo "*";
    }
    for ($n3 = 1; $n3 <= $n1; $n3++) 
    { 
        echo "*";
    }
    echo "\n";
}
