http://www.highcharts.com/stock/demo/basic-line 我的json.php代码：
<?php
header("content-type: application/json");
define('HOST', 'localhost');
define('USER', 'root');
define('PASSWORD', 'Super_Password');
define('NAME_BD', 'bd');
$connect = mysql_connect(HOST, USER, PASSWORD)
or die("error"
.mysql_error( ));
// print ("no error");
mysql_select_db(NAME_BD, $connect)
or die ("error"
.mysql_error( ));
$result = mysql_query("SELECT UNIX_TIMESTAMP(`Time`) * 1000 as datetime, `Current A` as A FROM `TT`")
or die ("error".mysql_error( ));
// echo "all good";
while ($row = mysql_fetch_array($result)) {
$data[] = $row['datetime'];
$datab[] = $row['A'];
}
echo '?(' . "\n" . '['. "\n";
$count = count($data);
for ($i=0; $i<$count; $i++)
{
echo '['. str_replace('"', "", json_encode($data[$i], JSON_HEX_APOS)) . ',' . str_replace('"', "", json_encode($datab[$i], JSON$
}
//echo '('. json_encode(join($data, ',')) . ')';
echo ']);';
?>
但它不起作用：当我刷新页面时，我看不到图表

for ($i=0; $i<$count; $i++)
{
echo '['.
str_replace('"', "", json_encode($data[$i], JSON_HEX_APOS)) . ',' .
str_replace('"', "", json_encode($datab[$i], JSON$ <----- What is this? Also missing 2 closing parenthesis ))
}
在echo JSON$结束时，你有str_replace()这究竟是什么？更不用说你在最终json_encode()和JSON$中错过了一个右括号，其中包括Polymer(
{
is: "paperspinner-dom",
behaviors: [Polymer.NeonAnimationRunnerBehavior],
properties:
{
opened:
{
type: Boolean
},
animationConfig:
{
value: function()
{
return {
'showSpinner':
{
name: 'bounce-in-animation',
node: this,
timing:
{
duration: 1000
}
},
'hideSpinner':
{
name: 'fade-out-animation',
node: this
}
}
}
}
},
runSpinnerAnimation: function(){
this.playAnimation('showSpinner');
}
});。
总之，您似乎有一些需要解决的语法错误。

oooo sory 缺少代码
$count = count($data);
for ($i=0; $i<$count; $i++)
{
echo '['. str_replace('"', "", json_encode($data[$i], JSON_HEX_APOS)) . ',' . str_replace('"', "", json_encode($datab[$i], JSON_HEX_APOS)) .']' . ',' . "\n";
}
//echo '('. json_encode(join($data, ',')) . ')';
echo ']);';
?>
在控制台0错误。
