{
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
$urls = array();
$urlsToReplace = array();
if(preg_match_all($reg_exUrl, $str, $urls)) {
$numOfMatches = count($urls[0]);
$numOfUrlsToReplace = 0;
for($i=0; $i<$numOfMatches; $i++) {
$alreadyAdded = false;
$numOfUrlsToReplace = count($urlsToReplace);
for($j=0; $j<$numOfUrlsToReplace; $j++) {
if($urlsToReplace[$j] == $urls[0][$i]) {
$alreadyAdded = true;
}
}
if(!$alreadyAdded) {
array_push($urlsToReplace, $urls[0][$i]);
}
}
$numOfUrlsToReplace = count($urlsToReplace);
for($i=0; $i<$numOfUrlsToReplace; $i++) {
$str = str_replace($urlsToReplace[$i], "<a target='_balnk' href=\"".$urlsToReplace[$i]."\">".$urlsToReplace[$i]."</a> ", $str);

8 Things Productive People Do During the Workday

Forget about your job title or profession – everyone is looking for ways to be more productive at work. It’s time to set down your gallon-sized container of coffee, toss out your three-page to-do list, and put an end to those ridiculously long emails you’ve been sending.

Experiencing a highly productive workday can feel euphoric. But contrary to popular belief, simply checking tasks off your to-do list isn’t really an indication of productivity. Truly productive people aren’t focused on doing more things; this is actually the opposite of productivity. If you really want to be productive, you’ve got to make a point to do fewer things.

Harness your productivity by taking note of these eight things:

1. Create a smaller to-do list. Getting things accomplished during your workday shouldn’t be about doing as much as possible in the sanctioned eight hours. It may be hard to swallow, but there’s nothing productive about piling together a slew of tasks in the form of a checklist. Take a less-is-more approach to your to-do list by only focusing on accomplishing things that matter.

2. Take breaks. You know that ache that fills your brain when you’ve been powering through tasks for several hours? This is due to your brain using up glucose. Too many people mistake this for a good feeling, rather than a signal to take a break. Go take a walk, grab something to eat, workout, or meditate – give your brain some resting time. Achieve more productivity during your workday by making a point to regularly clear your head. You’ll come back recharged and ready to achieve greater efficiency.

3. Follow the 80/20 rule. Did you know that only 20 percent of what you do each day produces 80 percent of your results? Eliminate the things that don’t matter during your workday: they have a minimal effect on your overall productivity. For example, on a project, systematically remove tasks until you end up with the 20 percent that gets the 80 percent of results.

4. Start your day by focusing on yourself. If you begin your morning by checking your email, it allows others to dictate what you accomplish. Set yourself in the right direction by ignoring your emails and taking the morning to focus on yourself, eat a good breakfast, meditate, or read the news.

5. Take on harder tasks earlier in the day. Knock out your most challenging work when your brain is most fresh. Save your busy work – if you have any – for when your afternoon slump rolls in.

6. Pick up the phone. The digital world has created poor communication habits. Email is a productivity killer and usually a distraction from tasks that actually matter. For example, people often copy multiple people on emails to get it off their plate – don't be a victim of this action. This distracts everyone else by creating noise against the tasks they’re trying to accomplish and is a sign of laziness. If you receive an email where many people are CC'd, do everyone a favor by BCCing them on your reply. If your email chain goes beyond two replies, it’s time to pick up the phone. Increase your productivity by scheduling a call.

7. Create a system. If you know certain things are ruining your daily productivity, create a system for managing them. Do you check your emails throughout the day? Plan a morning, afternoon, and evening time slot for managing your email. Otherwise, you’ll get distracted from accomplishing more important goals throughout the day.

8. Don’t confuse productivity with laziness. While no one likes admitting it, sheer laziness is the No. 1 contributor to lost productivity. In fact, a number of time-saving methods – take meetings and emails for example – are actually just ways to get out of doing real work. Place your focus on doing the things that matter most as efficiently and effectively as possible.

Remember, less is more when it comes to being productive during the workday.

What’s your secret to productive workdays?

Set php.ini Values Using .htaccess

Did you know that you can set php.ini values right inside the .htaccess file? It's actually very easy.

The .htaccess Code

#format
php_value setting_name setting_value#example
php_value  upload_max_filesize  10M

Of course you could simply place these in the .htaccess file, but .htaccess is a viable alternative if your host doesn't allow you to touch the php.ini file.

Prevent Your CSS and JavaScript Files From Being Cached

Some websites use highly volatile, oft-changing CSS and JavaScript files. In the case of these files, it's important that the developer prevent browsers from caching them. How do we do that? By using a phantom querystring, of course. We'll use PHP to tack the current time onto the file reference.

The PHP

[sourcecode language="php"]
<link href="/stylesheet.css?<?php echo time(); ?>" rel="stylesheet" type="text/css" >
<-- RENDERS -->
<link href="/stylesheet.css?1234567890" rel="stylesheet" type="text/css">

<script type="text/javascript" src="/site-script.js?<?php echo time(); ?>"></script>
<-- RENDERS -->
<script type="text/javascript" src="/site-script.js?1234567890"></script>
[/sourcecode]

It's a very simple technique and doesn't affect your CSS or JavaScript code in any way.

Android Detection with JavaScript or PHP

Hello Friends

You have a web application and you want to detect that if your Application is opened from android device than it will be redirect to any other URL that will be Android compatible.This is a good solution for you.

What's obvious is that Android development is a hot topic that will only grow. Here are a few methods by which you can detect iOS' main competitor: Android.

The JavaScript

Searching the user agent string for "Android" is the quickest method:

[sourcecode language="php"]
var ua = navigator.userAgent.toLowerCase();
var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
if(isAndroid)
{
// Do something! // Redirect to Android-site? window.location = 'http://android.viralsolani.co';
}

[/sourcecode]

The PHP

Again, we'll use PHP's strstr function to search for Android in the user agent:

[sourcecode language="php"]
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if(stripos($ua,'android') !== false){// && stripos($ua,'mobile') !== false) {
header('Location: http://android.viralsolani.co');
exit();
}
[/sourcecode]

Bonus! .htaccess Detection

We can even use .htaccess directives to detect and react to Android devices!

[sourcecode language="php"]
RewriteCond %{HTTP_USER_AGENT} ^.*Android.*$
RewriteRule ^(.*)$ http://android.viralsolani.co [R=301]
[/sourcecode]

And there you have it: three different Android device detection! Have fun with your mobile development!
