Hello,
I will just show how to quickly install Apache 2, PHP5, MYSQL and PHPmyAdmin in Ubuntu.
Install apache2 with:
$ sudo apt-get install apache2
Install PHP5:
$ sudo apt-get install php5 php5-common php5-cli
Install MYSQL:
$ sudo apt-get install mysql-client mysql-server
(During the installation it will ask you password for root user of MySQL)
Install PHPMyAdmin:
$ sudo apt-get install phpmyadmin
(It will ask the MySQL password and of the PHPMyAdmin user)
Best Regards,
Matheus

Hello
A few weeks ago I showed you how to create your own URL-Shortener. I decide to improve it, creating a simple system to control the number of access
First of all you need to add some tables to your data base:
CREATE TABLE access
(
aid INTEGER
UNSIGNED NOT NULL AUTO_INCREMENT,
urls_uid INTEGER
UNSIGNED NOT NULL,
information_iid INTEGER
UNSIGNED NOT NULL,
date DATE
NULL,
PRIMARY KEY(aid
),
INDEX access_FKIndex1
(information_iid
),
INDEX access_FKIndex2
(urls_uid
)
);
CREATE TABLE information (
iid INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
ip VARCHAR(255) NULL,
PRIMARY KEY(iid)
);
After this you should do a modification in your function-little-url.php in the function take_url($url):
function take_lurl
($lurl) {
global $link;
$q = "SELECT * FROM `urls` WHERE `unique_chars` = ‘".$lurl."’";
$r = mysql_query($q, $link); // Realiza consulta.
if(mysql_num_rows($r)>0
) {
$info = mysql_fetch_array($r);
$url = $info["url"]; // Pega endereço real
$uid = $info["uid"]; // Pega ID do endereço
$ip = $_SERVER[‘REMOTE_ADDR’]; // Pega IP do usuário
$qr = "select iid from `information` where ip = ‘".$ip."’" ;
$rr = mysql_query($qr, $link); // Procura se este IP já está no banco de dados
if(mysql_num_rows($rr)>0) { // Caso esteja insere somente um acesso novo proveniente deste IP
$iid = mysql_result($rr,0,"iid");
mysql_query("INSERT INTO `access` (urls_uid,information_iid,date) values (".$uid.", ".$iid.", now())", $link);
} else { // Caso não esteja, cria um registro com este IP e após cria um acesso.
$qr = mysql_query("INSERT INTO `information` (ip) values (‘".$ip."’)", $link);
$iid = mysql_insert_id($qr);
mysql_query("INSERT INTO `access` (urls_uid,information_iid,date) values (".$uid.", ".$iid.", now())", $link);
}
} else {
echo "Sorry, link not found!";
}
return $url;
}
In this System there is a table with IPs that already accessed some URL, when a URL is accessed it verify the IP, if it is on the table just create an access to this IP in the new address. Otherwise, add the IP and create the access to the address.

Good Night,
Here I will show you how to create your own url shortener.
First of all you need to create a table like this:
CREATE TABLE IF NOT EXISTS `urls` (
`uid` int(11) NOT NULL auto_increment,
`url` text default NULL,
`unique_chars` varchar(25) BINARY NOT NULL,
PRIMARY KEY (`uid`),
UNIQUE KEY `unique_chars` (`unique_chars`)
);
This code was taken from Abhise in this post “Create your own tinyurl with php and mySQL” that was my bigest reference, from it I took some functions and update other ones to be more efficient. For an example I changed the field to BINARY so it be CASE SENSITIVE (aaaa different from AAAA)
The Abhise says to create many files, I particularly, created one file with all functions where I add all the functions and just called the functions in the files.
