problem in recursion handling

[chintupintu03]

Hello all,

I need your help in this recursion problem.

I would like to show a random number on a page, as long as it is viewed.

Value '1000' passed to the function is an arbitary value, there is nothing special in other value.

---

<table>
<tr>
<?php
$number_code=doSomething(1000) ;

?>
<font color="#<?php echo $number_code ; ?>" >
</tr>
</table>

<?PHP
function doSomething($curr_val)
{

if ($curr_val > 0)
{
$var_1 = array(1,2,3,4) ;
$var_2 = array(1,2,3,4) ;
$var_3 = array(1,2,3,4) ;
$var_4 = array(1,2,3,4) ;

$temp_1 = rand(1,count($var_1)) ;
$temp_2 = rand(1,count($var_2)) ;
$temp_3 = rand(1,count($var_3)) ;
$temp_4 = rand(1,count($var_4)) ;

$number_formed = $var_1[$temp_1]." ".$var_2[$temp_2]." ".$var_3[$temp_3]." ".$var_4[$temp_4] ;

// $curr_val-- ;
$number_formed = doSomething($curr_val);

}

return $number_formed;
}
$color_code = doSomething(1000);
?>

---

When I execute this code, the error message shown is "The document contains no data".

Can anybody help me out in this?

Thanks in advance.

// $curr_val-- ;

looks like a comment 😉

Hello mrhappiness,

Thanks for the reply. Yes, the line $curr_val-- ; I put in comments, because, I want to call the function in endless loop.

In other words, I am using arbitary value ( in this case 1000) as an argument and trying to create set of random numbers and to us it for color of the font.

There is one more correction at the bottom of the code. Instead of,
$color_code = doSomething(1000);

it should be $number_code=doSomething(1000) ;

Can you help in this ?

You really believe, that a script that runs endlessly at the webserver will end and send output to the browser?
