我尝试了许多用PHP生成“Line Google Chart”的方法，有或没有json我每次尝试都会得到“没有列”错误。只想做几个月的笔记。我想做Counts /一个月的天数图。我怎么能解决它？
代码;
.
.
.
$google_array = array();
foreach($column_day_names["Jan"] as $key => $value) {
$google_array[] = array($key => $value);
}
$json_first=json_encode($google_array);
echo $json_first . "\xA";
$json = json_encode($google_array);
$json = str_replace("{", "[", $json);
$json = str_replace("}", "]", $json);
echo $json;
Jan Array的First_json输出：
[{ “01”：1}，{ “02”：1}，{ “03”：6}，{ “04”：1}，{ “05”：3}，{ “08”：1 }，{ “10”：1}，{ “11”：1}，{ “12”：1}，{ “13”：1}，{ “16”：1}，{ “17”：1}， { “18”：2}，{ “20”：1}，{ “21”：2}，{ “22”：2}，{ “23”：1}，{ “25”：1}，{” 27 “：2}，{” 28 “：1}，{” 29 “：1}，{” 30 “：3}，{” 31" ：1}]
Jan Array的第二个Json输出：
[[ “01”：1]，[ “02”：1]，[ “03”：6]，[ “04”：1]，[ “05”：3]，[ “08”：1 ]，[ “10”：1]，[ “11”：1]，[ “12”：1]，[ “13”：1]，[ “16”：1]，[ “17”：1]， [ “18”：2]，[ “20”：1]，[ “21”：2]，[ “22”：2]，[ “23”：1]，[ “25”：1]，[” 27 “：2]，[” 28 “：1]，[” 29 “：1]，[” 30 “：3]，[” 31" ：1]
