php+highchats生成动态统计图_php实例

代码如下:
series: [{
type: 'pie',
name: 'Browser share',
data: [
['Firefox', 45.0],
['IE', 26.8],
{
name: 'Chrome',
y: 12.8,
sliced: true,
selected: true
},
['Safari', 8.5],
['Opera', 6.2],
['Others', 0.7]
]
}]

主要看这段：

代码如下:
{
name: 'Chrome',
y: 12.8,
sliced: true,
selected: true
}

代码如下:












area();
/**
* 地区接口
* name名称
* y数据值
*
*/
function area()
{
$b = array(
array('name'=>'上海', 'y'=>28.2),
array('name'=>'北京', 'y'=>48.2),
array('name'=>'广东', 'y'=>18.2),
);
$data = json_encode($b);
echo($data);
}
?>

以下是php输出json数据，供js使用:

代码如下:
$strs = @file("/proc/net/dev");
for ($i = 2; $i < count($strs); $i++ )
{
preg_match_all( "/([^\s]+):[\s]{0,}(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)/", $strs[$i], $info );
/* $NetInput[$i] = formatsize($info[2][0]);
$NetOut[$i] = formatsize($info[10][0]);
*/
$tmo = round($info[2][0]/1024/1024, 5);
$tmo2 = round($tmo / 1024, 5);
$NetInput[$i] = $tmo2;
$tmp = round($info[10][0]/1024/1024, 5);
$tmp2 = round($tmp / 1024, 5);
$NetOut[$i] = $tmp2;

}

$arr = array();
if (false !== ($strs = @file("/proc/net/dev"))) :
for ($i = 2; $i < count($strs); $i++ ) :
preg_match_all( "/([^\s]+):[\s]{0,}(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)\s+(\d+)/", $strs[$i], $info );
$arr[$i]["name"] = $info[1][0];
$arr[$i]["data"][0] = $NetInput[$i];
$arr[$i]["data"][1] = $NetOut[$i];

endfor;
endif;
echo(json_encode($arr));
?>

输出：

代码如下:
{"2":{"name":"lo","data":[0,0]},"3":{"name":"eth0","data":[0.40377,0.00353]}}

js调用:

代码如下:
series: [
ds[2], ds[3]
]
