我有这个PHP代码如何让它生成从1到16的随机长度

Question

I have this php code how can i make it generate random from 1 to 10

$seed = str_split('aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStTuUvVwWxXyYzZ123456789');
$rand = array_rand($seed, 16);
$convert = array_map(function($n){
    global $seed;
    return $seed[$n];
},$rand);

$var1 = implode('',$convert);

so need this one to show random not 16 like its there but random length from 1 to 16 each time user comes.

Here's a code snippet without using map

function generateRandString($length = 10) {
    $chars = 'abcdefghijklmnopqrstuvwxyz0123456789';
    $charsLength = strlen($chars);
    $randomString = '';
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $chars[rand(0, $charsLength - 1)];
    }
    return $randomString;
}
