php+highchats生成动态统计图

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:

        $data = json_encode($b); 
        echo($data); 
    } 
    ?> 
        </body> 
    </html>

以下是php输出json数据，供js使用:

代码如下:

<?php  
$strs = @file("/proc/net/dev");  
for ($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: [ 
    <span style="white-space:pre">                      </span>ds[2], ds[3] 
    <span style="white-space:pre">                  </span>]
