为什么我在使用此函数时遇到未识别的索引错误,它输出的代码是我想要的,但它也将错误引入页面?身份不明的索引错误
if($result) {
$jsonData = convert($result);
}
function convert($result) {
$i = 0;
$intermediate = array();
while($rows = mysqli_fetch_assoc($result)) {
$key = $rows['POS'];
$x = $i;
$y = $rows['COUNT'];
$intermediate[$key][] = array('x' => count($intermediate[$key]), 'y' => $y);
$i++;
}
$output = array();
foreach($intermediate as $key => $values) {
$output[] = array(
"key" => $key,
'values' => $values
);
}
return json_encode($output, JSON_NUMERIC_CHECK);
它返回的数据是
[{ “键”: “OW1”, “值”:[{ “×”:0, “Y”:4},{ “×”: 1, “Y”:3},{ “×”:2 “Y”:2},{ “×”:3, “Y”:1},{ “×”:4, “Y”:1} ]},{ “键”: “OW2”, “值”:[{ “×”:0, “Y”:4},{ “×”:1, “y” 的:2},{ “×”: 2, “Y”:1},{ “×”:3, “Y”:3},{ “×”:4, “Y”:2}]},{ “键”: “OW3”,“值“:[{” × “:0,” Y “:4},{” × “:1,” Y “:5},{” × “:2”,Y “:1},{” ד: 3, “Y”:2},{ “×”:4, “Y”:1}]}]
和错误这些
说明:未定义指数:OW1在C:\瓦帕\ WWW \ multibar.html.php 24行
说明:未定义指数:OW2在C:\瓦帕\ WWW \ multibar.html.php上线24
说明:未定义指数:OW3在C:\瓦帕\ WWW \ multibar.html.php上第24行
完美工作,非常感谢! – Engl12 2014-10-28 19:09:23
