- //所谓断字 (word break)，即一个单词可在转行时断开的地方。这一函数将在断字处截断字符串。
- // Please acknowledge use of this code by including this header.
- function myTruncate($string, $limit, $break=".", $pad="...") {
- // return with no change if string is shorter than $limit
- if(strlen($string) <= $limit)
- return $string;
- // is $break present between $limit and the end of the string?
- if(false !== ($breakpoint = strpos($string, $break, $limit))) {
- if($breakpoint < strlen($string) - 1) {
- $string = substr($string, 0, $breakpoint) . $pad;
- }
- }
- return $string;
- }
- /***** Example ****/
- $short_string=myTruncate($long_string, 100, ' ');
- ?>
