短文本，PHP [英] Short Text, PHP

问题描述

我得到了这个功能:

function shorter($text, $chars_limit) {
  if (strlen($text) > $chars_limit) 
    return substr($text, 0, strrpos(substr($text, 0, $chars_limit), " ")).'...';
  else return $text;
}

如果我使用 echo short($input, 11) 它工作正常，但如果输入中有一些空格，否则输入看起来像:

and if I use echo shorter($input, 11) it works ok, but if there are some white spaces in the input, otherwise for the input looking like:

wwwwwwwwwww

wwwwwwwwwww

函数将把它改成:

...(3 个点).

我不想把它改成这样:

www ...

你知道如何重建这个脚本吗?提前致谢.

Have you got any ideas how to rebuild this script? Thank you in advance.

推荐答案

我假设您只想输入.如果它比 X 长，则在 X 处将其截断并添加...".

Im assuming you just want to take an input. If it is longer than X then cut it off at X and add "...".

// Start function
function shorter($text, $chars_limit)
{
    // Check if length is larger than the character limit
    if (strlen($text) > $chars_limit)
    {
        // If so, cut the string at the character limit
        $new_text = substr($text, 0, $chars_limit);
        // Trim off white space
        $new_text = trim($new_text);
        // Add at end of text ...
        return $new_text . "...";
    }
    // If not just return the text as is
    else
    {
    return $text;
    }
}

我没有测试过这个，但它应该可以工作.:)

I didn't test this, but it should work. :)
