It is usual when writing a list of items to separate each item with a comma, except the last two items, which are separated with the word "and". I recently needed to implement a function that took a string and converted it into a list of this type so I thought I would expand on it and post it here.
Apache can be set up to log all sorts of information. As of Apache 2.2 the basic log file format that a fresh install of Apache will produce will have the following format:
%h %l %u %t "%r" %>s %b
Which doesn't mean a lot to the uninitiated, so here is a short explanation of each.
Lots of applications require a user to input a URL and lots of problems occur as a result. I was recently looking for something that would take a URL as an input and allow me to make sure that is was formatted properly. There wasn't anything that did this so I decided to write it myself.
To round a number in PHP you can use one of three functions, these are round(), ceil() and floor(). All of these functions take number as the input and will round the value depending on the function used.
To round to the closest integer use the round() function.
