修复PHP支持的标准JSON数据格式

PHP的json_decode无法解析的JSON数据,代码如下：

1
2
$json = "{rst:5,c:[ [1018485,2,0,0,0,0,'','0-0','','',2,0,2],[1049809,17,0,0,0,0,'','','','',1,0,1],[1049813,17,0,0,0,0,'','','','',1,0,1],[1049810,17,0,0,0,0,'','','','',1,0,1]],fn:135388}";
echo json_decode($json);

//结果输出: null

存在的问题：

  1. Value没有使用双引号括起，而是使用了单引号
  2. Key没有被双引号括起

修复代码：

1
preg_replace('@([\w_0-9]+):@', '"\1":', str_replace('\'', '"', $json));

执行后的结果：

1
2
echo $json;
{"rst":5,"c":[ [1018485,2,0,0,0,0,"","0-0","","",2,0,2],[1049809,17,0,0,0,0,"","","","",1,0,1],[1049813,17,0,0,0,0,"","","","",1,0,1],[1049810,17,0,0,0,0,"","","","",1,0,1]],"fn":135388}
