如何在PHP中的关键字后面找到以下x个字符？

Question

I want to be able to only store the 11 characters following a certain keyword (watch?v=) in PHP, nothing after and nothing before. How do I achieve this?

Answer 1

Use strpos() to find the watch?v=, then use the substr() method to get 11 characters after.

docs for the strpos function: http://us2.php.net/strpos

docs for the substr function: http://www.php.net/manual/en/function.substr.php
