Multiple MYSQL queries vs. Multiple php foreach loops -

-

database structure:

id  galleryid                 type     file_name       description 1   `artists_2010-01-15_7c1ec`  `image`  `band602.jpg`   `red umbrella promo` 2   `artists_2010-01-15_7c1ec`  `image`  `nov7.jpg`      `cd release party` 3   `artists_2010-01-15_7c1ec`  `video`  `band.flv`      `presskit`

i'm going pull images out 1 section of application, videos on another, etc. better make multiple mysql queries each section so:

$query = mysql_query("select * galleries galleryid='$galleryid' && type='image');

...or should building associative array , looping through array on , on whenever need use result set?

thanks thoughts.

it depends what's more important: readability or performance. i'd expect single query , prefilling php arrays faster execute, since database connections expensive, simple query each section more readable.

unless know (and not hope) you're going huge amount of traffic i'd go separate queries , worry optimising if looks it'll problem. @ point there'll other things you'll want anyway, such building data access layer , adding caching.

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
