Bonjour,
j'ai un script php pour faire le calcul des pr des sites.
Le calcul des pr ne marche plus
pouvez vous me venir en aide merci

<?php

class GooglePR
{
/*
* convert a string to a 32-bit integer
*/
function StrToNum($Str, $Check, $Magic)
{
$Int32Unit = 4294967296; // 2^32

$length = strlen($Str);
for ($i = 0; $i < $length; $i++)
{
$Check *= $Magic;
//If the float is beyond the boundaries of integer (usually +/- 2.15e+9 = 2^31),
// the result of converting to integer is undefined
// refer to http://www.php.net/manual/en/language.types.integer.php
if ($Check >= $Int32Unit)
{
$Check = ($Check - $Int32Unit * (int) ($Check / $Int32Unit));
//if the check less than -2^31
$Check = ($Check < -2147483648) ? ($Check + $Int32Unit) : $Check;
}
$Check += ord($Str{$i});
}
return $Check;
}

/*
* Genearate a hash for a url
*/
function HashURL($String)

Commences par regarder le retour de la fonction file().
Si sans rien modifier du script il ne fonctionne plus il faut plutôt se pencher sur les données qu'il utilise.
