• Disable errors in PHP

  - by spacemonkey

  How to disable errors just for particular php function, and in the same time to know that the error occurred? For instance, I use a php function parse_url, to parse an array of urls, sometimes it returns an error, what I want to do is to parse next url once error occurs, and not to show it(error) on the screen.

• standard c library for escaping a string.

  - by rampion

  Is there a standard C library function to escape C-strings? For example, if I had the C string: char example[] = "first line\nsecond line: \"inner quotes\""; And I wanted to print "first line\nsecond line: \"inner quotes\"" Is there a library function that will do that transformation for me? Rolling my own just seems a little silly. Bonus points if I can give it a length to escape (so it stops before or beyond the \0).

  - by wndsr

  Assuming we are running a compiled C++ binary: Is passing around an int (e.g. function to function, or writing it into variables) slower than passing around structs/class objects like the following? class myClass { int a; int b; char c; vector d; string e; }

• How to document class attributes with NaturalDocs

  - by HWende

  Via """ Function: myfunc Parameters: a : First parameter b : First parameter """ I can document a function and it gets listed in the class summary. How can I do something similar with attributes?

• How can I get the correct headers automatically given a filetype in PHP?

  - by incrediman

  A few times I've run into situations where I'd like to be able to include a file using PHP, and depending on the included filetype, output the appropriate headers. In the past I've just done this manually by switch/casing the extension type with the appropriate content-type headers. However what I'm wondering now is if there's a function like get_header($filename) or maybe get_contenttype($extension) For example if I wanted to route all requests for media through a php file, I could use that function to output the correct headers.

• Repeat elements of vector in R

  - by bshor

  Hi, I'm trying to repeat the elements of vector a, b number of times. That is, a="abc" should be "aabbcc" if y = 2. Why doesn't either of the following code examples work? sapply(a, function (x) rep(x,b)) and from the plyr package, aaply(a, function (x) rep(x,b)) I know I'm missing something very obvious ...

• Is it possible to get a pointer to String^'s internal array in C++/CLI?

  - by CannibalSmith

  The goal is to avoid copying the string data when I need a const wchar_t*. The answer seems to be yes, but the function PtrToStringChars doesn't have its own MSDN entry (it's only mentioned in the KB and blogs as a trick). That made me suspicious and I want to check with you guys. Is it safe to use that function?

• Newbie: understanding main and IO()

  - by user1640285

  While learning Haskell I am wondering when an IO action will be performed. In several places I found descriptions like this: "What’s special about I/O actions is that if they fall into the main function, they are performed." But in the following example, 'greet' never returns and therefore nothing should be printed. import Control.Monad main = greet greet = forever $ putStrLn "Hello World!" Or maybe I should ask: what does it mean to "fall into the main function"?

• C++: Chr() and unichr() equivalent?

  - by alex

  I could have sworn I used a chr() function 40 minutes ago but can't find the file. I know it can go up to 256 so I use this: std::string chars = ""; chars += (char) 42; //etc So that's alright, but I really want to access unicode characters. Can I do (w_char) 512? Or maybe something just like the unichr() function in python, I just can't find a way to access any of those characters.
