Sencha Touch: Expense Tracker app development tutorial

I started developing Expense Tracker App using Sencha Touch 2.3 and build the app using Phonegap/Cordova. I thought that i need to keep track my daily expenses in my mobile phone and also i need to know how much i am spending based on categories (Tea/Coffee, Drinks, Film etc). These informations will be helpful for me to plan my future financial savings.

I almost completed the app development and installed it in my Phone (iPhone and Android). I faced lot of issues and obstaclus while developing this app. I like to share my app development experience to all my readers and also willing to explain the implementation with the help of source code here as a Post Series.

Here is the list of post series for Expenses Tracker App development

You can download the source code for the Expense Tracker App from the below GitHub Url

I hope you enjoyed all of my post series on Expense Tracker app development tutorial. See you soon on next set of blog post series.

PHP: How to insert array before/after the key into the existing array

Today, i like to share two handy array functions in PHP, which are used to insert array before/after the key into the existing array.

Insert array before function

This function will insert key/value as well as array before the key in the existing array.

 * Inserts a new key/value before the key in the array.
 * @param $key  The key to insert before.
 * @param $array  An array to insert in to.
 * @param $new_key  The key/array to insert.
 * @param $new_value  An value to insert.
 * @return array
public function array_insert_before($key, array $array, $new_key, $new_value = null) {
    if (array_key_exists($key, $array)) {
        $new = array();
        foreach($array as $k = > $value) {
            if ($k === $key) {
                if (is_array($new_key) && count($new_key) > 0) {
                    $new = array_merge($new, $new_key);
                } else {
                    $new[$new_key] = $new_value;
            $new[$k] = $value;
        return $new;
    return false;
