php方法:N个字符间插入其它字符的方法

最近做一个excel下载功能,为了解决每一列宽度,只能手动调整分行,于是写了一个自动换行的方法

function mbstringtoarray($str,$cut_len,$charset,$inter="<br>") {
  $strlen=mb_strlen($str,$charset);
  $array=array();
  while($strlen){
    $array[]=mb_substr($str,0,$cut_len,$charset);
    $str=mb_substr($str,$cut_len,$strlen-$cut_len,$charset);
    $strlen=mb_strlen($str,$charset);
    
  }
  return implode($inter,$array);
}
Copy after login

用起来还不错,呵呵,这个也解决了中文字符乱码的问题。

1The basic unit of Unicode computer storage is the byte, which is composed of 8 bits. Since English only consists of 26 letters plus a number of symbols, English characters can be stored directly in bytes. But other languages ​​(such as Chinese, Japanese, Korean, etc.) have to use multiple bytes for encoding due to the large number of characters. With the spread of computer technology, non-Latin character encoding technology continues to develop, but there are still two major limitations: no multi-language support: the encoding scheme of one language cannot be used in another language and there is no unified standard: for example There are many encoding standards in Chinese such as GBK, GB2312, GB18030, etc. Since the encoding methods are not unified, developers need to convert back and forth between different encodings, and many errors will inevitably occur.

Python's built-in function repr() can express objects in the form of strings to facilitate our identification. This is the "string representation". repr() obtains the string representation of an object through the special method __repr__.
