Return a size in bytes,kilobytes,megabytes and gigabytes for given array or string. Can be used if you want to check performance for some script.
<?php
function array_size($arr) {
$byte = 0;
foreach ($arr as $key => $val) {
$byte += is_array($val) ? array_size($val) : mb_strlen($val);
}
$kb = number_format($byte / 1024, 4);
$mb = number_format($byte / 1048576, 4);
$gb = number_format($byte / 1073741824, 4);
$result = array('Bytes: ' => $byte, 'Kilobytes: ' => $kb, 'Megabytes: ' => $mb, 'Gigabytes: ' => $gb);

Created July 17, 2015 13:41
Give rgb color and percent and function will return you same color but brighter according to percent. From 0% to 100%. Example: <?php echo rgb_gen('64,128,0', '50%'); ?>
<?php
function rgb_gen($rgb, $percent) {
$cleaned_percent = preg_replace("/\..*|%/", "", $percent);
$rgb_increment = 100 - $cleaned_percent;
$rgb_arr = explode(',', $rgb);
$rgb_arr[0] + $rgb_increment <= 255 ? $rgb_arr[0]+=$rgb_increment : $rgb_arr[0] = 255;
$rgb_arr[1] + $rgb_increment <= 255 ? $rgb_arr[1]+=$rgb_increment : $rgb_arr[1] = 255;
$rgb_arr[2] + $rgb_increment <= 255 ? $rgb_arr[2]+=$rgb_increment : $rgb_arr[2] = 255;
$new_rgb = implode(',', $rgb_arr);
return $new_rgb;

How To Configure Nginx as a Reverse Proxy for Apache (Linux)
I will consider that you have three servers. First one with apache, second one with nginx server and third with bind.
1: Go to bind server (/etc/bind/zones/) and setup new A records to site that we will run.
- nginx5 IN A 192.168.0.1
- apache5 IN A 192.168.0.2
2: Set vhost with new site for port 8080 (/etc/apache2/sites-available/)
<VirtualHost *:8080>
ServerName apache5.mysite.com
ServerAdmin webmaster@localhost

Last active March 23, 2016 09:45
Difference Between Forward Proxy And Reverse Proxy
The previous answers were accurate, but perhaps too terse. I will try to add some examples.
First of all, the word "proxy" describes someone or something acting on behalf of someone else.
In the computer realm, we are talking about one server acting on the behalf of another computer.
For the purposes of accessibility, I will limit my discussion to web proxies - however, the idea of a proxy is not limited to web sites.
FORWARD proxy
Most discussion of web proxies refers to the type of proxy known as a "forward proxy."

Example about prepare statements. No SQL Injections... no bugs, be safe
<?php
$servername = "localhost";
$username = "root";
$password = "toor";
$dbname = "test";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
