Question

批发者为信封内的所有环节设定了20年的固定性质长度。

So even if a user uses an url shortening service like bit.ly and pastes url shorter than 20 characters all urls will finally be given a length of 20 characters by twitter.

我很想知道,如何计算eet(包括一个或多个短ur)的最后长度,这样它就与PHP保持了140个特性。

Answer 1

You can replace your links with some generic text via regex and count the whole length with mb_strlen() afterwards. mb_strlen because Twitter counts Multibyte chars as one char.

$tweet =  Check this: http://stackoverflow.com/questions/8864767/calculate-final-tweet-character-length-in-php ;
$length = mb_strlen(preg_replace( ~https?://([^s]*)~ ,  http://8901234567890 , $tweet),  UTF-8 );
var_dump($length); // int(32);

或许你必须调整比照(无效果园)的比照。
