Question

$num = 39; //sets number of weeks - there are only 38 rounds so 39 is fine
$num2 = $num-1; //for adding the previous weeks table - rest of code not added yet 

while($num > 0) // set to 0 so that when it reaches week 1 it stops
{
    if ( file_exists('./results/week'.$num.'.html'))  
    {
        echo '<h1>week '.$num.'</h1>';
        echo (include_once('./results/week'.$num.'.html'));
        $num = $num - 1;
    }
    else
    {
        $num = $num - 1;
    }
}

Hi
I’m trying to add a number of tables (html files) to a page and this code seems to work, however it adds a 1 to the end of each table so I get:

Week 3
Name  Result
John  4
Bob   3
1
Week 2
Name  Result
Bob   6
John  1
1

etc.
Could some kind soul please tell me where this 1 is coming from? And how to get rid of it?
I’d be most grateful.
Ta Rich

Answer 1

Don’t echo include_once, just include_once. The 1 is the echoed return value of the include_once call.
