我几天前发布了关于this problem的代码段。我试图从另一方面审视这个问题。
所以，我有一个查询，我想从其输出中填写一个json文件。它包含更多记录，而不仅仅是一个。问题是，我发现/我写过的所有代码只将第一条记录粘贴到带有cols的文件中。我认为没有关于这个问题的现有教程。
更新：示例输出：
Array (
[cols] => Array
(
[0] => Array
(
[id] =>
[label] => Name
[pattern] =>
[type] => string
)
[1] => Array
(
[id] =>
[label] => Start
[pattern] =>
[type] => date
)
[2] => Array
(
[id] =>
[label] => End
[pattern] =>
[type] => date
)
)
[rows] => Array
(
[0] => Array
(
[c] => Array
(
[0] => Array
(
[v] => X
)
[1] => Array
(
[v] => Date(2014,08,18,21,00,00)
)
[2] => Array
(
[v] => Date(2014,08,18,23,00,00)
)
)
)
[1] => Array
(
[c] => Array
(
[0] => Array
(
[v] => Y
)
[1] => Array
(
[v] => Date(2014,08,18,21,00,00)
)
[2] => Array
(
[v] => Date(2014,08,18,22,00,00)
)
)
)
[2] => Array
(
[c] => Array
(
[0] => Array
(
[v] => Z
)
[1] => Array
(
[v] => Date(2014,08,18,23,00,00)
)
[2] => Array
(
[v] => Date(2014,08,18,23,30,00)
)
)
)
)
)

<强>解决方案： 这是一个字符编码问题，可以使用json_last_error（）方法检测到：
switch (json_last_error()) {
case JSON_ERROR_NONE:
echo ' - No errors';
break;
case JSON_ERROR_DEPTH:
echo ' - Maximum stack depth exceeded';
break;
case JSON_ERROR_STATE_MISMATCH:
echo ' - Underflow or the modes mismatch';
break;
case JSON_ERROR_CTRL_CHAR:
echo ' - Unexpected control character found';
break;
case JSON_ERROR_SYNTAX:
echo ' - Syntax error, malformed JSON';
break;
case JSON_ERROR_UTF8:
echo ' - Malformed UTF-8 characters, possibly incorrectly encoded';
break;
default:
echo ' - Unknown error';
break;
}
