用"..."缩短字符串身体 [英] Shorten string with a "..." body

问题描述

就像iPhone的应用程序名称过长一样，名称也被缩短.我真的很喜欢这种缩短名称或字符串的方法，而不是在其后附加"..."子句的方法.抱歉，如果我感到困惑，我无法解释我要做什么.因此，我将举一个例子！

Just like the the iPhone's app names that run to long, the name gets shortened. I really like this method of shorting a name or a string rather then appending a "..." clause to it. Sorry if I am being confusing, I'm having trouble explaining what I am trying to do. So I'll show an example!

这就是我要在短字符串后附加"..."的功能(在PHP中)

This is what I have, to append "..." to a shortened string (In PHP)

<?php
  $string = "This is a test script";

  if (strlen($string) >= 14)
    echo(substr($string), 0, 13). "..."); // This is a test...
  else
    echo($string); // This is a test script
?>

我想拆分名称或字符串，并保留第一个要说的10个字符，然后在中间插入"..."，最后取字符串的结尾5个字母并显示它们.我在想一些类似的事情:

I would like to split up the name or string and keep the first say 10 characters, then insert "..." in the middle and lastly take the ending 5 letters of the string and display them. I was thinking of something along the lines of:

<?php
  $string = "This is a test script";

  if (strlen($string) >= 20)
    echo(substr($string, 0, 10). "..." .substr($string, 15, 20)); //This is a ...script
  else
    echo($string);
?>

但是要意识到，最后只剩下5个字母，这是行不通的.任何指向写入方向的指针都很好，谢谢！

But realize that will not work in the regards that there are more then just 5 letters in the end. Any pointers into the write direction would be great, Thanks!

推荐答案

if (strlen($string) >= 20) {
    echo substr($string, 0, 10). " ... " . substr($string, -5);
}
else {
    echo $string;
}
