将文字拆分成批次换行

Question

我希望有更好的解决问题能力的人可以帮助我。我有一个textarea，我所要做的就是将文本分成50个字符，并将这些行提供给另一个应用程序。没问题。但是我忘记了\ n换行符。如果有人提出换行符，我也必须将其作为一条单独的行。这是我当前的代码（$ content是原始文本）。我敢肯定，有一种简单的方法我无法实现。

 $div = strlen($content)/50; 


     $x=0; 
     while ($x<$div) { 

     $substr=$x*50; 

     $text = substr($content,$substr,50); 


     if (trim($text)!="") { 

        echo $text . "<br>"; 

       } 

     $x++; 


       }

你看过PHP的wordwrap和nl2br函数吗？

$result = wordwrap($content, 50, "\n"); // first, wrap 
$result = nl2br($result); // then, include html breaks 

所以，这样的：

$content = <<<EXAMPLE

I have a textarea and all I had to do is split the text into 50 chars and feed the lines to another app.
