Ubuntu /var/log/uvcdynctrl-udev.log佔容量問題

之前系統警告/var滿了，
查看一下發現/var/log佔了很大的空間，
其中95%的佔用來自於/var/log/uvcdynctrl-udev.log
因為當初以為/var/log是必須定期手動清理的，
（其實系統會自動清理）
於是就直接
sudo rm -r /var/log/*
接著我的apache http server找不到error.log，
就無法啟動了...

其實下面這個解決方法不能解決根本問題，
他只是強制不讓uvcdynctrl寫入/var/log
但是至少uvcdynctrl-udev.log不會再出現了...

有更好的方法以後會再補上！

解決方法：
sudo cp /lib/udev/uvcdynctrl /lib/udev/uvcdynctrl_backup
#備份原始的/lib/udev/uvcdynctrl
gksu gedit /lib/udev/uvcdynctrl
#執行gedit來編輯/lib/udev/uvcdynctrl
#找到"debug=1"並改成"debug=0"
sudo rm /var/log/uvcdynctrl-udev.log
#刪除討人厭佔很大空間的uvcdynctrl-udev.log

php的箭頭符號（減號+大於）

php的「->」用來引用某個class中的函式或變數，
或者是說調用某個class中的函式或變數。

example:

class a
{
    function  b()
    {
        echo 'hello';
    }
}

$c = new a;
$c -> b();

output: hello
