Aquí van unos snippets de código PHP que pueden hacernos más sencillas algunas tareas a la hora de llevar nuestra web:

Validar una dirección de email:

include('EmailAddressValidator.php');

$validator = new EmailAddressValidator;
if ($validator->check_email_address('test@example.org')) {
    // Email address is technically valid
}
else {
    // Email not valid
}

Conseguir la dirección IP:

function getRealIpAddr(){
	if (!empty($_SERVER['HTTP_CLIENT_IP'])){
		//check ip from share internet
		$ip = $_SERVER['HTTP_CLIENT_IP'];
	}
	elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){
		//to check ip is pass from proxy
		$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
	}
	else{
		$ip = $_SERVER['REMOTE_ADDR'];
	}
	return $ip;
}

Generador de contraseñas:

function generatePassword($length=9, $strength=0) {
    $vowels = 'aeuy';
    $consonants = 'bdghjmnpqrstvz';
    if ($strength & 1) {
        $consonants .= 'BDGHJLMNPQRSTVWXZ';
    }
    if ($strength & 2) {
        $vowels .= "AEUY";
    }
    if ($strength & 4) {
        $consonants .= '23456789';
    }
    if ($strength & 8) {
        $consonants .= '@#$%';
    }

    $password = '';
    $alt = time() % 2;
    for ($i = 0; $i < $length; $i++) {
        if ($alt == 1) {
            $password .= $consonants[(rand() % strlen($consonants))];
            $alt = 0;
        } else {
            $password .= $vowels[(rand() % strlen($vowels))];
            $alt = 1;
        }
    }
    return $password;
}

Enviar un email:

include("class.phpmailer.php");
$mail = new PHPMailer();
$mail->From = 'noreply@htmlblog.net';
$mail->FromName = 'HTML Blog';
$mail->Host = 'smtp.site.com';
$mail->Mailer = 'smtp';
$mail->Subject = 'My Subject';
$mail->IsHTML(true);
$body = 'Hello<br/>How are you ?';
$textBody = 'Hello, how are you ?';
$mail->Body = $body;
$mail->AltBody = $textBody;
$mail->AddAddress('asvin [@] gmail.com');
if(!$mail->Send())
	echo 'There has been a mail error !';
