PHP Ordering

Navigation
5

I have a PHP code that pulls an XML and plays on the screen however I would like it to run in random order and not the order that is in XML.

Is this possible?

Code that I'm using.

PHP 

$xml = simplexml_load_file('produtos.xml');
foreach ($xml as $oferta){
$a = "<div class='produto'><a href=" . $oferta->links->link["url"]. ">". $oferta->offerName. "</a><br>";
$a .= "" . $oferta->offerShortName. "<br>";
$a .= "<img src=" . $oferta->thumbnail["url"]. " width='80%;'><br>";
$a .= "R$" . $oferta->price->value.  "<br>";
$a .= "<a href=" . $oferta->links->link["url"]. ">comprar</a><br>"; 
$a .= "<a href=" . $oferta->links->link["url"]. "><img src=" . $oferta->seller->thumbnail["url"]. "></a><br></div>";
echo $a;

XML

Use a count to count the amount of arrays that contain the $ xml variable, use that number to build a for, and mount another random numbered array with a limit to the number of arrays in your $ xml, / p> 

$qtd_array = count($xml->offer) - 1;    
for($i= 0; $i<= $qtd_array; $i++){
    $num_alea = rand(0, $qtd_array);
    if($i >= 1){
        while(in_array($num_alea, $num_aleatorio)){
             $num_alea = rand(0, $qtd_array);
        }
    }
$num_aleatorio[$i] = $num_alea;

$a = "<div class='produto'><a href=" . $xml->offer[$num_aleatorio[$i]]->links->link["url"]. ">". 
$xml->offer[$num_aleatorio[$i]]->offerName. "</a><br>";
$a .= "" . $xml->offer[$num_aleatorio[$i]]->offerShortName. "<br>";
$a .= "<img src=" . $xml->offer[$num_aleatorio[$i]]->thumbnail["url"]. " width='80%;'><br>";
$a .= "R$" . $xml->offer[$num_aleatorio[$i]]->price->value.  "<br>";
$a .= "<a href=" .$xml->offer[$num_aleatorio[$i]]->links->link["url"]. ">comprar</a><br>"; 
$a .= "<a href=" .$xml->offer[$num_aleatorio[$i]]->links->link["url"]. "><img src=" . $xml->offer[$num_aleatorio[$i]]->seller->thumbnail["url"]. "></a><br></div>";
echo $a;

Try this If you are not sure, just return here;)

shuffle($xml->offer) before for .

This function will randomize the object offer within XML .

See if it works like this.
