referencing info from an If statement

[severndigital]

ok so I want to run a function, but I only want to run it once. even if i call the page again.

how do I run the function ONLY 1 time and then after re-calling the page reference the varibles values.

 

Here is what i have

 

function buryTreasure($h,$w){
//some math and data manipulation here
$per = 10;
          $res = array();

         for($i = 0; $i < $per; $i++){
                 $res[] = rand(0,100);
         }
return $res;
}

now i want to run that function ONCE to get my result. But how do make it so that it I can use the result of the function?

 

Thanks,

C

once for 1 session? or once for all time?

 

If its just once per session, use a session variable.

 

<?php
// check if its been called or not
if($_SESSION['treasure'] == 0) {
buryTreasure(1,1);
$_SESSION['treasure'] = 1;
} else {
  echo "Function has already been called this session!";
}

 

or if its just once forever. Use a database to store 0 by default for the treasure. And then when its been called like above, update the database and set it to 1.
