Question

如果一个单词超过一定数量的字符，是否有一个可以自动添加spacer的函数？例如，给定一个包含100个字符的单词，它将在第50个字符处发布一个空格键。我正在创建一个评论系统，如果有人发布了类似的内容：

它会弄乱我的布局外观，因为单词中没有空格。

Answer 1

使用CSS而不是更改实际的单词/字符串：

div{
    display:table;
    word-break:break-all;
}

要回答PHP，你可以使用像这样的函数（如果你真的需要）：

<?php
$str = '1234567890123456789012345678901234567890123456789 123456789012345678901234567890123456789012345678901234567890 ASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDFASDF';

function addSpace($str,$int){
 $output = '';
 $words = explode(' ', $str);
 foreach ($words as $word):
     $new = '';
     while(strlen($word)>$int){
     $new .= substr($word, 0, $int). ' ';
     $word = substr($word, $int);
     }
     $output .= "$new $word ";
 endforeach;
 return $output;
}
echo addSpace($str, 50);
?>

一个单词超过50个字符后自动空格键
