PHP 第 10 个逗号后换行

Question

我需要拆分以下字符串：

333 ,351 ,359 ,360 ,370 ,371 ,385 ,492 ,512 ,514 ,528 ,539 ,546 ,628 ,630 ,634 ,636 ,702 ,706 ,709 ,710 ,715 ,718 ,719 ,763 ,770 ,803 ,822 ,823

在最后的第 10 个逗号之后开始换行，是否有意义？

所以看起来像这样：

333 ,351 ,359 ,360 ,370 ,371 ,385 ,492 ,512 ,514 ,

528 ,539 ,546 ,628 ,630 ,634 ,636 ,702 ,706 ,709 ,

710 ,715 ,718 ,719 ,763 ,770 ,803 ,822 ,823

Answer 1

假设 $string 是您之前的字符串：

<?php

$myArray = explode(",", $string);
$newString = "";
$count = 0;
foreach ($myArray as $value)
{
  $newString = $newString.$value.",";
  $count++;
  if ($count==10)
  {
    $count=0;
    $newString = $newString."\n";
  }
}

?>

Answer 2

这样就可以了...

$str = '333 ,351 ,359 ,360 ,370 ,371 ,385 ,492 ,512 ,514 ,528 ,539 ,546 ,628 ,630 ,634 ,636 ,702 ,706 ,709 ,710 ,715 ,718 ,719 ,763 ,770 ,803 ,822 ,823';

$iCount = 0;
foreach (explode(',',$str) as $iNum)
    echo $iNum.' ,'.(++$iCount % 10 == 0 ? '<br>' : '');

解释请看评论：-

 <?php
    error_reporting(E_ALL); // check if any error occur
    ini_set('display_errors',1); // display error
    $string = '333 ,351 ,359 ,360 ,370 ,371 ,385 ,492 ,512 ,514 ,528 ,539 ,546 ,628 ,630 ,634 ,636 ,702 ,706 ,709 ,710 ,715 ,718 ,719 ,763 ,770 ,803 ,822 ,823'; // original string
    echo $string; // echo original string
    $array = explode(',',$string); // explode string with comma to make it array
    echo "<pre/>";print_r($array); // print array
    $chunked_array = array_chunk($array,10); // chunk array to each 10 counts and make a multidimensional array
    $new_string = ''; // create a new empty string
    foreach ($chunked_array as $chunked_ar){ // iterate through multi-dimensional array 

      $new_string .= implode(',',$chunked_ar)."\n"; // convert each array to string and add new line and assign it to new string variable
    }
    echo $new_string; // echo new variable.
  ?>

注意：添加 error_reporting 代码（<?php 后的前两行）始终是找出错误并解决它们的好习惯。谢谢

你可以用一条线做到这一点。

preg_replace('/((.*?,){10})/', "\n", $text);
