Please, verify the script below,
this error occurred with others values in this variable too.
------------------------------------------------------------
<?php

function retorna_cnpj($cnpj)
   $new_var = ereg_replace("[/\.\-\",$cnpj);
   $new_var = settype($new_var,"integer");
   return $new_var;
}

$w_cnpj = "12.345.678/0002-12"
 
echo retorna_cnpj($w_cnpj);

?>
------------------------------------------------------------

It must return 12345678000212 as integer, but 
php return for me the number: 2147483647

Thanks

First, settype returns boolean, see:
http://www.php.net/manual/function.settype.php

Second, if you want to convert something to integer, use
(int)$var, not settype.

Third, maximal available integer number in PHP is
2147483647. This is what gets returned. Use $var+0 if you
want to get numeric value form string, no matter what large.
