PHP CHALLANGE - PART 1 -

Salut,

Sa se faca un calculator in limbajul de programare PHP care sa afiseze rezultatul in litere

4+4 rezultatul afisat sa fie "opt' nu "8"

Si daca cineva incearca sa introduca litere in calcul sa se blocheze accesul acelui browser timp de 60 minute.

Si scripturile postate sa fie cat mai diferite de la utilizator la utilizator.

Scriptul meu


<?php
if(isset($_COOKIE['1d7ae0532395d267dd3526beb707240b'])){
	echo "<font color='red'><center><h2>Ai fost blocat pe acest site</h2></center></font>";
	}else{

	if(isset($_POST['a'])){

		$array = array("1","2","3","4","5","6","7","8","9","10");
		$litere = array("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","s","t","u","v","w","x","y","z");
		$array2 = array("unu","doi","trei","patru","cinci","sase","sapte","opt","noua","zece");
		$a = htmlentities(strtolower(str_replace($litere,null,($_POST['a']))));
		$b = htmlentities(strtolower(str_replace($litere,null,($_POST['b']))));
			echo str_replace($array,$array2,$a + $;
		if($a ==0  && $b == 0){
			setcookie(md5("blocat"),md5("blocat"),time()+6500);
		}


	}else{
		echo '<form action="" method="POST">
  <input type="text" name="a"><br> + 
  <input type="text" name="b"><br>:
  <input type="submit" value="Submit">
</form> ';
	}
}
	?>

Am uitat cat de mult ador si urasc php-ul in acelasi timp.


<!DOCTYPE html>
<html>
<body>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
  <input type="text" name="a"> + <input type="text" name="b">
  <input type="submit">
</form>

<?php

function retnum($num) {
  $var = array( 1 => "unu",
                2 => "doi",
                3 => "trei",
                4 => "patru",
                5 => "cinci",
                6 => "sase",
                7 => "sapte",
                8 => "opt",
                9 => "noua",
                0 => "zero" );
  $mun = strrev($num); $hue = "";
  while ((int)$mun > 0) {
    $hue .= $var[$mun%10] . " ";
    $mun /= 10;
  }
  return $hue;
}

if (isset($_COOKIE["lol_cookies"])) {
  $hue = array("nope", "rekt", ":^)");
  echo $hue[array_rand($hue)];
} else {
    if ((isset($_POST["a"])) && (isset($_POST["b"]))) {
    $a = $_POST["a"]; $b = $_POST["b"];
    if ( ($a != null && !is_numeric($a)) ||
         ($b != null && !is_numeric($) ) {
      setcookie("lol_cookies", "shrekt :^)", time()+(60*60));
    } else {
      $num = $a + $b;
      echo retnum($num);
    }
  }
}

?>

@open la $array si $array2 mai bine il declari pe 0, respectiv zero in loc de 10 si zece!

Stiu ca e mai fain sa verifici daca este setata o variabila sau nu, dar asa e mai scurt:


<?php

ini_set('display_errors', FALSE);

if (preg_match('/[a-z]/i', $_POST['a'] . $_POST['b']) || $_COOKIE['blocked']) {
	if (!$_COOKIE['blocked']) setcookie('blocked', 1, time() + 3600);
	die('Access denied!');
}

?>
<form method="post">
	<input type="text" name="a" value="0" /> +
	<input type="text" name="b" value="0" /> =
	<input type="text" value="<?=['zero', 'unu', 'doi', 'trei', 'patru', 'cinci', 'sase', 'sapte', 'opt', 'noua', 'zece'][$_POST['a'] + $_POST['b']]?>" disabled />
	<input type="submit" />
</form>

Foarte bine lucrat.

Plm calculator inseamna macar sa poata face toate operatiile de baza + ,* ,- ,/ .

Ce sa mai zic de evaluarea unei expresii matematice cu paranteze si cu ordinea efectuarii operatiilor.

<?php class calculator{ private $cifre=array(0=>"zero",1=>"unu",2=>"doi" - Pastebin.com

Ms @proof nu mai folosi nicodata PHP_SELF nesintetizat baga scrip.php/"><script>alert(1)</script>

Daca totti a adaugat varianta cea mai scurta si dany cea mai complexa, adaug si eu ceva intre. Adica nu face mare lucru da are si multe linii

Ca informatii, aduna doar numere intregi pozitive de lungime limitata.
