  • Does single or double quote matter in str_ireplace in PHP ?

    - by Richards
    Hi, I've to replace newline (\n) with & in a string so that the received data could be parsed with parse_str() into array. The thing is that when I put \n in single quote it somehow turns out as to be replaced with a space: str_ireplace(array('&', '+', '\n'), array('', '', '&'), $response) "id=1 name=name gender=gender age=age friends=friends" But when I put \n in double quotes then it works just fine: str_ireplace(array('&', '+', "\n"), array('', '', '&'), $response) "id=1&name=name&gender=gender&age=age&friends=friends" Why is that so?

  • Line for signature in markdown

    - by JBarberU
    I'm writing a document using markdown, which I'm exporting to a PDF using pandoc. At the end of the document I need to have space for signatures on a printed copy of the PDF. I've tried to find how to draw a line with a fixed width, but so far I only got to escaping the underscore character, which doesn't feel quite right. It's as if I'm missing something, this couldn't possibly be that unusual to want to do. Any help or pointers are greatly appreciated.

  • jQuery: Circulate plugin: stopping midway in animation

    - by kelly
    Has anyone had any luck in altering the plug-in code so that one might animate an object in "3d" space for only a 1/4 or 1/2 turn? As it stands, an object must complete a full circle before stopping or looping. And for those who haven't seen it yet: http://css-tricks.com/examples/Circulate/

  • Can you explicitly set a structure layout/alignment in C++ as you can in C#?

    - by Gary Willoughby
    In C# you have nice alignment attributes such as this: [StructLayout(LayoutKind.Explicit)] public struct Message { [FieldOffset(0)] public int a; [FieldOffset(4)] public short b; [FieldOffset(6)] public int c; [FieldOffset(22)] //Leave some empty space just for the heck of it. public DateTime dt; } Which gives you fine control on how you need your structure to be layed out in memory. Is there such a thing in standard C++?

  • What's the worst name you've seen for a product? [closed]

    - by Dean J
    (Community wiki from the start.) What's the worst name you've seen for a product? It might be a euphemism the company didn't know about, maybe something like Penetrode (from Office Space). It might be something impossible to do a web search on, like the band named "Download". It might be some combination of random syllables that's just awful. But no matter what, it's bad. What's the worst you've seen?

  • Find out how much storage a row is taking up in the database

    - by Vaccano
    Is there a way to find out how much space (on disk) a row in my database takes up? I would love to see it for SQL Server CE, but failing that SQL Server 2008 works (I am storing about the same data in both). The reason I ask is that I have a Image column in my SQL Server CE db (it is a varbinary[max] in the SQL 2008 db) and I need to know now many rows I can store before I max out the memory on my device.

  • What is a good Ruby on Rails hosting service?

    - by Owen
    I'm looking to deploy a new Ruby on Rails project I'm working on but need hosting. A managed server is overkill for me. I just need shared space. I'd like to go with a service that specializes in Ruby on Rails. I've looked at SpeedyRails and RailsPlayground and they both seem to have pros and cons. Does anyone have experience with either? Does anyone have a different recommendation?
