<?php

            for($numbers=0;$numbers<3000;$numbers++)
            {
                if($numberArray[$numbers]>$numberArray[$numbers+1])
                {

                $nplusone=substr($wordArray[$words+1],$p,1);
                while($n==$onplusone)

                }
                if($n>$nplusone)
                {
                    $temp=$wordArray[$i];
                    $wordArray[$words]=$wordArray[$words+1];
                    $wordArray[$words+1]=$temp;
                    $pass=false;
                }
            }
        }
        echo "<br>Bubble sort algoritms strādā, izpildot savu doto funkciju ". (microtime(true)-$time)*30 . " sekundēs. <br>";
    }
}

?>

Error log spits out 3000 errors all the same saying

PHP Notice: Undefined offset: 0 on line 14

which is

if($numberArray[$numbers]>$numberArray[$numbers+1])

I'm clueless as to what's the problem. There are no colons missing (I'm pretty sure).

Where is `$numberArray` defined? What does it contain? `print_r($numberArray)` — user3783243, Dec 17 '20 at 11:22
$numberArray is defined in the php file which is added at the start (include('dati.php')) — Pauls Vilks, Dec 17 '20 at 11:24
You are adding via `http`, not as a file, so that is run through the server and processed. Is that intended? Does `print_r` give output? — user3783243, Dec 17 '20 at 11:26
it is intended to run through a server and `print_r` doesn't give an output — Pauls Vilks, Dec 17 '20 at 11:30
I meant `http://pvilks.progpamati.lv/PHP_07/dati.php` is running through the `http://pvilks.progpamati.lv` server. So a file such as ` — user3783243, Dec 17 '20 at 11:33
yeah that cleared up things, I was supposed to only `include('dati.php');` — Pauls Vilks, Dec 17 '20 at 11:37
