问题 If I have a URL like asdf.com/index.php?a=0&b=2, then using $_GET for a would be 0 and for b would be 2. However, the term I put into a single $_GET function has an ampersand in it already, like a=Steak&Cheese. Is there a way to make ampersands work without the $_GET variable thinking its job ends when the ampersand shows up (therefore not pulling the entire term)? 回答1: urlencode() it so & turns into %26 . If you need to make a query string out of some parameters, you can use http_build_query

问题 I have a simple form that generates a new photo gallery, sending the title and a description to MySQL and redirecting the user to a page where they can upload photos. Everything worked fine until the ampersand entered the equation. The information is sent from a jQuery modal dialog to a PHP page which then submits the entry to the database. After Ajax completes successfully, the user is sent to the upload page with a GET URL to tell the page what album it is uploading to -- $.ajax ({ type:

问题 I'm designing a (more or less) RESTful internal web service running on ASP.NET and IIS. I want clients to be able to pass query details to the server when accessing large collections of entries, using JSON to describe the query in a known manner. The issue is that the queries sent to the server will be complex; they may include aggregation, filtering, mapping—essentially anything that is supported by the LINQ query operators. This will result in relatively large JSON objects representing the

问题 I have stored xts objects inside an environment. Can I subset these objects while they are stored in an environment, i.e. act upon them "in-place"? Can I extract these objects by referring to their colname ? Below an example of what I'm getting at. # environment in which to store data data <- new.env() # Set data tickers of interest tickers <- c("FEDFUNDS", "GDPPOT", "DGS10") # import data from FRED database library("quantmod") dta <- getSymbols( tickers , src = "FRED" , env = data , adjust =
