The clean and fast way for changing date format in PHP
<?php
$date = new DateTime('now');
echo $date->format('d/m/Y').PHP_EOL; // format: day/month/year
echo $date->format('m-d-Y').PHP_EOL; // format: month-day-year
echo $date->format('Y-m-d').PHP_EOL; // format: year-month-day
// add 3 days to current date and output using format year-day-month
echo $date->setTimestamp( strtotime('+3 days', $date->getTimestamp()) )->format('Y-d-m');

Răspunsul la problema de Luni - 11.Mar.2013

Deși variabila name primită de la utilizator prin $_GET sau $_POST este filtrată, lipsa ghilimelelor de la atributul href fac acest cod vulnerabil la un atac XSS.

Standardele susțin și obligă folosirea ghilimelelor la valoarea oricărui atribut HTML. Versiunea simplă a motivului este că ghilimelele au ca scop delimitarea valorilor și atunci când ele nu există, browser-ul nu știe unde începe și unde se termină valoarea aferentă unui anume atribut, iar drept urmare lucruri urâte se pot întâmpla.

Să luăm drept exemplu codul postat de mine anterior. Putem specifica un nume folosind $_GET sau $_POST ; de dragul ușurinței, hai să folosim $_GET:

Problema #2

Există greșeli în următorul cod ?

function valid_email($email) {
    //Regular expression string to evaluate the email
    $regex = '/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/';

    //Checks for a match to the expression
    if (preg_match($regex, $email)) {
 //Check for valid domain(helps avoid eronious emails)
