for extra credit i have been given the option of creating a php script that will print out a ppascal triangle
ex.
1
11
121
1331
14641

and im wondering if there is a funtion i don't know about that will allow me to create variables within a for loop?

i would include the code i have soo far but thaats on another computer, i may edit this post at lunch

the first link i found:
http://mathworld.wolfram.com/PascalsTriangle.html

explains all you need to implement it....

a little websearch will probably give you some code too...

yes there is code on the web but since this is a project for extra credig I won't give you the url, would kind of defeat the purpose.

? You can create variables anywhere:

Code: Select all

$foo = 3;
for ($i=0; $i<4; $i++) {
  $bar = 5;
  if ($bar) {
    $baz = 8;
    echo $bar;
  }
}
I don't believe I understand your question.

your response was the most helpful,
i think theres a way i can plot the numbers of the triangle on a proverbial "grid" using Mersenne numbers and Fibonacci numbers but i don't have to time to spew some code right now

thanks for the help
