一个php截取指定字符串之间的字符串的类

php类：

str = $str; $this->start_str = $start_str; $this->end_str = $end_str; $this->start_pos = strpos($this->str,$this->start_str)+strlen($this->start_str); $this->end_pos = strpos($this->str,$this->end_str); $this->c_str_l = $this->end_pos - $this->start_pos; $this->contents = substr($this->str,$this->start_pos,$this->c_str_l); return $this->contents; } } ?>

 

用法：

get_str('[123456789]','[',']'); ?>
