php發送log至syslog server
範例
<?php
function BSD_Syslog($msg,$severity=7, $program="php-test",$remote_ip='127.0.0.1',$remote_port=514){

$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
socket_sendto($sock, $syslog_message, strlen($syslog_message), 0, $remote_ip, (int)$remote_port);
socket_close($sock);
}

透過run-avrdude燒錄Arduino Yun
由於不小心在上一支程式用太多記憶體(接近99%)
造成Arduino Yun無法透過IDE Upload程式了
原本打算用 Arduino as ISP方式用另外一台Arduino Yun來燒錄.
但是試不出來.
後來在論壇上( https://forum.arduino.cc/index.php?topic=355657.0 )看到可以用run-avrdude來進行燒錄
因此就先用Blink建立最簡單的hex後,
再把檔案傳到Arduino上.
接著ssh進去yun後,透過下列指令進行燒錄
merge-sketch-with-bootloader.lua Blink.ino.hex
run-avrdude Blink.ino.hex如果只是單純使用run-avrdude,也是可以燒錄.
但是IDE依然無法燒錄.
後來用merge-sketch-with-bootloader.lua對hex檔案天加入了bootloader後.
就可以讓IDE燒錄了.
php 常用函式
mk_dir: 遞迴建立資料夾
ls: 遞迴取得所有檔案清單(不含目錄)
function mk_dir($dir, $mode = 0777){
if (is_dir($dir) || @mkdir($dir,$mode)) return TRUE;
if (!mk_dir(dirname($dir),$mode)) return FALSE;
return @mkdir($dir,$mode);
}
function ls($path,$loop=true){
$items=[];
$files=scandir($path);
foreach($files as $item){
if($item!="." && $item!=".."){
$file="${path}/${item}";
if(is_dir($file) && $loop){
$items=array_merge($items,ls($file));
}
else if(is_file($file)){
$items[]=($file); //realpath
}
}
}
return $items;
}
