我在Ubuntu 12.04上安装了phonegap 3.0.0-0.14.3.
我想用android模拟器运行应用程序.当我跑步时,phonegap run android我得到以下内容:
[phonegap] compiling Android...
[phonegap] successfully compiled Android app
[phonegap] trying to install app onto device
[phonegap] no device was found
[phonegap] trying to install app onto emulator
[error] An error occurred while emulating/deploying the android project.Warning : [ --debug | --release | --nobuild ] not specified, defaulting to --debug
Cleaning project...
该应用程序运行到设备没有问题.
请帮忙!
我有一个问题,我想使用explode函数拆分一个字符串变量,但有一个限制,想象下一个字符串变量具有下一个值:
$data = "3, 18, 'My name is john, i like to play piano'";
使用explode函数:explode(",",$ data),输出将是:
array(
[0] => 3,
[1] => 18,
[2] => 'My name is john,
[3] => i like to play piano'
);
我的目标是用逗号分隔变量$ data,排除''chatacters之间的变量.
例如 array(
[0] => 3,
[1] => 18,
[2] => 'My name is john, i like to play piano'
);
如果有人能告诉我这样做的方法,我将不胜感激.
有谁知道如何CAST(0x993902CE AS DATETIME)从SQL SERVER(smalldatetime二进制格式)到MYSQL？
我CAST(0X993902CE AS DATETIME)在mysql中尝试但是当它返回'2007-05-25 11:58:00'时它返回NULL.
如果有人能告诉我这样做的方法,我将不胜感激.
