If you’ve been developing with PHP for a while, you’ve probably come across this situation in the past:
<?php
foreach ($somearray as &$element) {
$element = some_function($element);
}
It’s a common sight: taking an array and running (well, walking) its elements through a particular function. Luckily, PHP provides a simple yet powerful function to overcome this: array_walk().

But given that the exchange rate changes every other second, we use services from one of the trusted sites to show the latest exchange rates. Here we take help of Google to find the latest currency exchange rate and convert the currency to required currency. I hope this piece of code helps you.

Supporters of the Stop Online Piracy Act, or SOPA (and its Senate-sister the Protect Intellectual Property Act, PIPA) legislation — like the Motion Picture Association of America (MPAA) — argue that legislation is needed because online piracy puts jobs and industries at risk.
While I agree that content piracy is a real problem, the language and implications of SOPA has the potential to hurt the very industries and content creators the bills purport to protect.
Google Analytics is much more robust than most people give it credit for. Contrary to popular belief, it can do most of the things more advanced analytics suites can do, except Google does it for free.
Many web designers and developers complain about the limitations of Google Analytics. At first glance, it doesn’t seem as powerful as some of the other web analytics suites out there because it doesn’t let you track outbound links or see data in real time. So, developers flock to premium products like Clicky and Mint, but those services can be expensive, especially if your web project isn’t generating any income yet. Also, while they fix some of the limitations inherent in Google Analytics, they lack some of the Google-only tie-in features, such as Adwords and Adsense tracking.
