Sometimes you have to manage memory in PHP

I’m currently working on a Google maps based project for a client, which deals with large numbers of points and overlays. At one point in the program I was getting around 16,000 Lat/Lng points from the database, which formed 70 polygons. Before the polygons could be rendered on Google Maps, I needed to group the points by polygon in an array. (more…)

PHP Convert Array to Object

Just a quick one today, I’ve seen a few people asking how to convert an array to an object in PHP. All the responses to these questions seem to involve creating a recursive function to loop through the array and create corresponding properties in a stdClass for each key in the array.

There happens to be a MUCH simpler way built in to PHP from version 5.2, all you need to do is this:

$object = json_decode(json_encode($array));

This works because when you encode an array using JSON in PHP, non-numeric keys become object properties, so when the JSON string is convered back to an object, the new properties remain instead of being turned back into array keys.

Give it a try, it works perfectly.

How to install Zend framework with XAMPP

I, like most web developers, use the excellent XAMPP to develop and test PHP/MySQL websites and applications on my local machine. The problem is the XAMPP doesn’t come with the Zend framework installed by default.

If you want to develop with Zend, you could always use Zend Server CE instead of XAMPP, as Zend Server comes with the Zend framework installed. The downside to that is that the Zend server is not as simple to set up and use as XAMPP, and if you’ve already been using XAMPP, migrating to Zend server can be a real pain in the ass, and you can’t run both XAMPP and Zend server together.

If you google installing Zend in XAMPP, there are many different guides, all of which seem overly complicated. Installing the zend framework under XAMPP is actually a lot simpler than most guides online would suggest, and using the following guide you should be able to run Zend Apps in your existing XAMPP environment in a matter of minutes.
