//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;

}
