I’ll copy here the most interesting of it.

HTTP with PHP Sockets

// don’t need to specify http, it’s the default protocol
$hostname = “www.google.com”;
$port = 80;

// create and configure the client socket
$fp = fsockopen($hostname, $port); // optional: $error_number, $error_string, $connect_timeout
if ($fp) {
stream_set_timeout($fp, 30); // seconds to wait for i/o operations

// send request headers
fwrite($fp, “GET / HTTP/1.1\r\n”);
fwrite($fp, “Host: $hostname\r\n”);
fwrite($fp, $additional_headers); // Accept, User-Agent, Referer, etc.
fwrite($fp, “Connection: close\r\n”);

// read response
$response = “”;
while (!feof($fp)) {
$response .= fgets($fp, 128);
}
echo $response;

// close the socket
fclose($fp);
}

Direct SSL Sockets in PHP

You don’t have to send request headers in the above example. You can actually connect to some servers and send raw text with fwrite. Because you have to implement the HTTP/HTTPS protocol yourself if you want it, sockets are considered “clean” connections.

// note that “ssl” is the protocol, NOT “https”
$hostname = “ssl://your-secure-site.com”;
$port = 443;

// create and configure the client socket
$fp = fsockopen($hostname, $port);
if ($fp) {
stream_set_timeout($fp, 30);

// send data (or build HTTPS headers similar to first example)
fwrite($fp, “your message goes here”);

// read response
while (!feof($fp)) {
echo fgets($fp, 128);
}

// close the socket
fclose($fp);
}

HTTPS via cURL

PHP doesn’t directly support attaching client certificates to web requests with fsockopen, so you have to use the cURL library.
$url = “https://your-secure-site.com/secure-service.php”;
$port = 443;

// POST data, formatted just like a GET query string
$request = “name=hb&age=27&site=arguments.callee.info”;

// the client certificate path MUST be a physical path, not url
$certificate = “C:\\certificates\\test.crt”; // windows example
$certificate = “/etc/pki/tls/private/test.crt”; // unix/linux example
$password = ‘mypassword’; // client certificate’s key

// more details at http://php.net/curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PORT, $port);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSLCERT, $certificate);
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, $password);

// fetch response and close the socket
$response = curl_exec($ch);
curl_close($ch);

today i’ll be talking about how to export / import your Excel file into you your database using the PHP and the CSV file format.
First of all we need an Excel file with our data.

Every row of the excel file should be the same format as the previous row (so that we can make our life easier), for example if we want to import a excel file with name/url addres corresponding to this name we should have our excel file in a format like this:

After u have the file in this excel format u should hit -> File -> Save as -> CSV (Comma Delimited) or more ofter its Called “Comma Separated Values”. For the comma separator use “;” if it asks you. So after you save the file in the CSV file format you should have something like this after you open the file with notepad etc.:

in this case we use “;” for comma separator.

ok lets get now to the Databse – in my case i will be using mysql, so for the sample excel file above you can use this code to create your database:

CREATE DATABASE MerchantManager;
USE MerchantManager;
CREATE TABLE IF NOT EXISTS `merchants` (
`MerchantID` int(11) NOT NULL AUTO_INCREMENT,
`MerchantTimestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`MerchantName` varchar(256) NOT NULL,
`MerchantURL` varchar(256) NOT NULL,
PRIMARY KEY (`MerchantID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=185 ;

after we create the database we are going to write some function in php that can import the data into our Database:

we can create now a new file – “import.php”

<?

function AddMerchant($name, $url){
$host = “localhost”;
$user = “root”;
$pass = “”; // use your mysql password
$db_name = “merchantmanager”;
$table = “merchants”;

mysqli_query(new mysqli($host, $user, $pass, $db_name), “INSERT INTO “.$table.” (`MerchantName`, `MerchantURL`) VALUES (‘$name’, ‘$url’)”);

}
?>

okz i hope it’s all clear for now, so let’s get to the php now
To export the CSV file into our database we are going to use:

“file_get_contents” function – http://bg.php.net/file_get_contents
and “explode” function – http://bg.php.net/manual/en/function.explode.php

so lets get started, after the “AddMerchant()” function that we wrote above, we will add the following code into the file “import.php”

$file = file_get_contents(“file.csv”); //we load the CSV file and put it in a variable

$rows = explode(“\n”, $file); //we brake the variable into array, using the new line as a condition

foreach($rows as $row){

$items = explode(“;”, $row); //we brake it again into another array using the “;” sign in our case
AddMerchant($items[0],$items[1]);// we get the first and the second value of the array (name and url)
echo “success”;

}

?>

Can you believe it’s that simple 3 lines of code and we managed to put the information from the excel file into the database.
