php+highchats生成動態統計圖實例代碼

編輯：關於PHP編程

分享下php+highchats生成動態統計圖的方法。

例子：

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] 
] 
}]

主要看這段：

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

以下是php輸出json數據，供js使用:


<?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)); 
?>

輸出：

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