I'm trying to execute a simple Bash Script from PHP script. I collect data from a HTML5 front end page, pass through ajax to the PHP script, take the variables and then, pass these to the .sh script, but I've got messages like: ./test_bash.sh: line 13: ./test.txt: Permission denied I tried to change the permissions chmod 777 test_bash.sh , tried to modify the sudoers.d file, tried this

I'm currently developing a couple of plugins for Sublime Text 2 on OS X and I would like to make them cross platform, meaning I have to find out if and where php.exe is installed. Right now I call /usr/bin/php in Python, which obviously works only on OS X and Linux: phppath = '/usr/bin/php'<br> pluginpath = sublime.packages_path() + '/HtmlTidy/tidy.php'<br> retval = os.system(
我目前正在为OS X上的Sublime Text 2开发几个插件,并且我想让它们跨平台,这意味着我必须找出php.exe是否安装以及在哪里安装。 现在我在Python中调用/usr/bin/php ,这显然只适用于OS X和Linux: phppath = '/usr/bin/php'<br> pluginpath = sublime.packages_path() + '/HtmlTidy/tidy.php'<br> retval = os.system( '%s "%s"' % ( phppath, scriptpath ) ) 但在Windows上,php.exe似乎没有definitve默认路径
So I recently discovered docker and vagrant, and I'm starting a new Php project in which I want to use both: Vagrant in order to have a interchangeable environment that all the developers can use. Docker for production, but also inside the vagrant machine so the development environment resembles the production one as closely as possible. The first approach is to have all the definition
所以我最近发现了docker和vagrant,并且我开始了一个新的Php项目,我在这个项目中使用了两个: Vagrant为了有一个可供所有开发人员使用的可互换环境。 用于生产的Docker,也包含在流浪机器内部,因此开发环境与生产环境尽可能接近。 第一种方法是使用此布局将所有定义文件与源代码放在同一个存储库中: /docker /machine1-web_server /Dockerfile /machine2-db_server /Dockerfile /machineX
I'm trying to obtain the first key of an associative array, without creating a temporary variable via array_keys() or the like, to pass by reference. Unfortunately both reset() and array_shift() take the array argument by reference, so neither seem to be viable results. With PHP 5.4 I'll be in heaven; array_keys($array)[0]; , but unfortunately this of course is not an option either.
我试图获取关联数组的第一个键,而不通过array_keys()或类似方法创建临时变量,以通过引用传递。 不幸的是, reset()和array_shift()通过引用获取数组参数,所以它们都不是可行的结果。 用PHP 5.4我会在天堂; array_keys($array)[0]; ,但不幸的是,这当然也不是一种选择。 我可以创建一个函数来实现这个目的,但是我只能想象有一些PHP的array_*函数会在单个语句中产生所需的结果 ,这是我无法想象或想出来的。 所以: $
