PHP - 以3为一组打印数组的值

Question

I have an array; the following

$arr = array(
    '1', 
    '2',
    '3',
    '4',
    '5',
    '6',
    '7',
    '8',
    '9',
);

and I want to print something like

• 1
• 2
• 3

• 4
• 5
• 6

• 7
• 8
• 9

My code only print the first 3

for($m = 0; $m < 9; $m++){
echo "<ul>";

for($i = 0; $i <3; $i++){
    echo "<li>";
    echo $arr[$i];
    echo "</li>";
}

echo "</ul>";
}

Really appreciate it!

You can use php array_chunk($arr,number of chunk)

$arr = array( '1', '2', '3', '4', '5', '6', '7', '8', '9');
    $chunkArray = array_chunk($arr,3);

    foreach ($chunkArray as $key => $value) {
        echo '<ul>';
        foreach ($value as $key1 => $value1) {
            echo '<li>'.$value1.'</li>';
        }
        echo '</ul>';

    }
