Question

I cannot figure out why this doesn’t work. It seems so simple.
It should output this.

Intro,First,Second,Third,First,Second,Third,First,Second,Third
Intro,First,Second,Third,First,Second,Third,First,Second,Third
Intro,First,Second,Third,First,Second,Third,First,Second,Third
Intro,First,Second,Third,First,Second,Third,First,Second,Third …etc

But it does not see the the $columnnum=0; and after the first line, it just goes keeps going.

Does anyone have any ideas?

$testarray = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21);
$columnnum = 0;
foreach ($testarray as $value) {
    $columnnum++;
    if ($columnnum == 1) {
        echo "Intro, ";
    }
    echo "First, ";
    echo "Second, ";
    echo "Third";
    if ($columnnum == 3) {
        $columnum = 0;
        echo "<br>";
    }
    echo " col: ", $columnnum;
}

Answer 1

You typoed $columnnum=0 near the end of the loop.

This should be more efficient:

echo str_repeat("Intro,".str_repeat("First,Second,Third",3)."<br>",7);
