Php FTP Functions ( phpfox )

This is a simple function to connect to an ftp and download the xml files from that ftp to a specified folder in our server

$ftp_server = 'abcdefg.com';      // FTP Server Address (exlucde ftp://)

        // Login to FTP Server
        $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
        // Verify Log In Status
        if ((!$conn_id) || (!$login_result))
        {
           Phpfox_Error::set('FTP connection has failed!Attempted to connect to'. $ftp_server.' for user'. $ftp_user_name);
        } else {
           Phpfox::addMessage('Connected to '. $ftp_server .', for user '. $ftp_user_name);

                // define some variables
// check whether the xml is already downloaded and saved in Database

                    $server_file = $currentFile;
                    // try to download $server_file and save to $local_file
                    if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY))
                    {

        {
            // reading each xml and fetching the datas.
            $xml=simplexml_load_file(Phpfox::getParam('core.dir_file').'xml/'.$valueXML['xml_name']);
// converting the xml object to array.
            $array = Phpfox::getService('moduleName')->object_to_array($xml);
}

// by printing this '$array' we will get the xml values as
echo '<pre>';
print_r($array);
echo '</pre>';

Very Simple PHP Captcha

Very Simple PHP Captcha :
Very easy and it requires only a couple lines of code. Please follow the below steps.

Step 1
The first step is to create a HTML form which is later submitted.
I assume you already have a HTML form, so I'll only focus on the captcha code and not all the other fields.
 
<?php
session_start();
echo '<form action="something.php" method="post">';
$rand_int1 = substr(mt_rand(),0,2);
$rand_int2 = substr(mt_rand(),0,1);
$rand_int3 = substr(mt_rand(),0,1);
$captcha_answer = $rand_int1 + $rand_int2 - $rand_int3;
$_SESSION['captcha_answer'] = $captcha_answer;
echo 'What is '.$rand_int1.' + '.$rand_int2.' - '.$rand_int3.'?<br>
<input type="text" name="captcha">
<input type="submit" value="Do captcha">
</form>';
?>


Step 2
The second step is collecting the form data and check if captcha is correct.
 
<?php
session_start();
$captcha = $_POST['captcha'];
$captcha_answer = $_SESSION['captcha_answer'];
 
if($captcha != $captcha_answer) {
    echo 'Captcha is incorrect!';
}
else {
    echo 'Captcha is correct, congratulations! :)';
}
?>

        FOR($currentYear = $startYear - 5; $currentYear <= $startYear+5;$currentYear++)
        {
            ECHO "<OPTION VALUE=\"$currentYear\"";
