Question

我想用一个空格分隔数字，数量为4。 1234567890，将成为1234 5678 90

我设法创建了一个脚本来实现这一目标，但它似乎超越了顶部，是否有更简单的方法来实现这一目标？

$num = 23853267362365;
$count = strlen($num)/4;

$new_num = array();
for ($x = 1; $x <= $count; $x++) {
    $num_len = strlen($num);
    if($num_len>4) {
        $new_num[] = substr($num,0,4);
        $num = substr($num,4,$num_len-4);
    }
}

$num = implode(' ',$new_num);

chunk_split()

Answer 2

非chunk_split()答案;不如Jessie Jackson的答案好，但适应任何长度。

$start_num = 23853267362365;
$chunk_length = 4; // change to whatever length you need
$count = ceil(strlen($num) / $chunk_length);

$concat =''; // initiate
for ($x = 0; $x < $count; $x++) {
   $concat .= substr($start_num, ($chunk_length * $x), $chunk_length) . ' ';
}

$new_num = rtrim($concat, ' ');
