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);

   echo $new_var . "<br>";

   $nada = settype($new_var,"integer");

   echo $new_var . "<br>";

   return $new_var;

}

$w_cnpj = "12.345.678/0002-12";

echo $w_cnpj . "<br>";

echo retorna_cnpj($w_cnpj) . "<br>";

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

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.
