  • PHP object class variable

    - by mck89
    I have built a class in PHP and I must declare a class variable as an object. Everytime I want to declare an empty object I use: $var=new stdClass; But if I use it to declare a class variable as class foo { var $bar=new stdClass; } a parse error occurs. Is there a way to do this or must I declare the class variable as an object in the constructor function? PS: I'm using PHP 4.

  • Ruby class variable is reset after rails app initialized

    - by Phuong Nguy?n
    I tried to assign a class static variable like this class QueryLogger < Logger @@query_logger_default_instance = nil def self.default_instance # Use global variable because static variable doesn't work @@query_logger_default_instance ||= self.new(STDOUT) end end In initializers folder of my rails app, I added a file with this code block ActiveRecord::Base.logger = QueryLogger.default_instance In a request (action of controller), I make a call to this: QueryLogger.default_instance. My assumption is that the call to default_instance will always report the same. However, it does not. Now I try to watch stuff in NetBeans by setting breakpoint inside default_instance. Thing happen as expected, the default_instance get called twice, one due to the initializer block and one due to the call to my action. Surprising thing is, in both times, @@query_logger_default_instance report nil inside NetBeans inspector. The first nil report is correct, but the second shocked me. It's look like static variable gets reset after rails app initialized. Is there some magic there?

  • Nginx: check content-length before file upload takes place

    - by robw
    I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website. I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large). I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded. Alternatively, a Rails solution would also be acceptable. Any help appreciated.

  • Sorting Python list based on the length of the string

    - by prosseek
    I want to sort a list of strings based on the string length. I tried to use sort as follows, but it doesn't seem to give me correct result. xs = ['dddd','a','bb','ccc'] print xs xs.sort(lambda x,y: len(x) < len(y)) print xs ['dddd', 'a', 'bb', 'ccc'] ['dddd', 'a', 'bb', 'ccc'] What might be wrong?

  • Variable disappears when I log in

    - by John
    Hello, I have profile page where the profile is retrieved via GET. The index file has this: $profile = $_GET['profile']; When I log in on the profile page, the $profile variable disappears. Here is the form action on the login function: <form name="login-form" id="login-form" method="post" action="./index.php"> (The $profile variable is separate of the login username.) How could I make the page retain the $profile variable? Thanks in advance, John

  • Environment Variable to determine the OS type (Windows XP, Windows 7)

    - by Santhosh
    I want to differrntiate between Windows XP and Windows 7 in a XML file. Thought i will use an environment variable for it inside the XML. However I could not find any system environment variable defined in windows that gives this information. I see the %OSTYPE% variable but it is only available in Windows 7. It is not defined in XP. Is there anyway i could do this? Note that i would like a solution which purely depends on system environment variables. I do not want to create new variables based on executing some command, because i want to use this variable in a XML file.

  • RSA key length and export limitations

    - by Alex Stamper
    I know, there are a lot of limitations to the length of used key (import and export limitations for nearly each country). Usually, it varies from 64 to 256 bits. To use more bits, it is obligatory to ask permission from authorities. But it is recommended to use 1024 bits keys for RSA as minimum! Does it mean that I cannot just use RSA without any problems with law and so on?

  • Does variable name length matter for performance C#?

    - by MadBoy
    I've been wondering if using long descriptive variable names in WinForms C# matters for performance? I'm asking this question since in AutoIt v3 (interpreted language) it was brought up that having variables with short names like aa instead of veryLongVariableName is much much faster (when program is bigger then 5 liner). I'm wondering if it's the same in C#?

  • Another passing variable through function jQuery/JS problem...

    - by dallen
    Here's my code: function mouseOver(variable) { return function() { $(variable).fadeIn(100); }; } function mouseOut(variable) { return function() { $(variable).fadeOut(100); }; } function lawyer(var1, var2, var3, var4) { return function() { $(var1).bind('mouseenter', mouseOver(var2)).bind('mouseleave', mouseOut(var2)).click( function() { $(var1).unbind('mouseenter').unbind('mouseleave'); $(var1).removeClass('off').addClass('on'); $(var3).bind('mouseenter', mouseOver(var4)).bind('mouseleave', mouseOut(var4)); $(var3).removeClass('on').addClass('off'); $(var4).hide(); }); } } lawyer("#group", ".b", "#group2", ".l"); What would be the reason for this not working? It works in that it hides $(var4).hide();, but clicking on the object doesn't seem to do anything. It works if I take the code out of a function and just copy/paste it a few times and change the targets. I'm not seeing it... Any help would be appreciated!
