php 如何解析这样的字符串PHP

Answer 1

首先，你想解析什么字符？达到什么目的？不说具体，很难具体回答你问题。
其次，php中解析字符串的函数特别多，功能也很丰富，基本上平时需求都能满足，你可以选用函数进行解析。参考http://www.w3school.com.cn/php/php_ref_string.asp。

Answer 2

如果想把上述字符串解析为数组的话，要是我来做，我会：
1.把上述字符串储存为一个数组；
2.计算该数组（或字符串）的长度；
3.采用循环（for,while等），依次判断每个字符，分辨出{},_[] 数字和字母；
4.把解析的结果依次用多维数组记录下来；
5.对这些数组，你就可以尽情使用了。上面所涉及到的字符串函数在我给出的链接网页上都有。

Answer 3

function parseConf($id){
        static $configList = array();
        if(empty($configList)){
            $path =  FCPATH.APPPATH.'config/data_sell.config';
            if (file_exists($path )) {
               $handle = fopen($path, "r");
                while (!feof($handle)) {
                    $buffer = fgets($handle);
                    preg_match('/\{data_sell,(\d+),.*\{new_item,(\d+),/',$buffer,$match_array);
                    if($match_array[1] && $match_array[2]){
                        $configList[$match_array[1]] = $match_array[2];
                    }
                }
                fclose($handle);
            }
        }        if(isset($configList[$id])){
            return $configList[$id];
        }
        return null;    }
