<?php
error_reporting(E_ALL);
$ser = 'a:5:{s:6:"lineas";a:1:{i:0;a:7:{s:7:"ldivisa";s:3:"eur";s:9:"letcambio";s:1:"1";s:9:"leimporte";s:3:"200";s:7:"letotal";s:3:"200";s:9:"ldtcambio";s:1:"1";s:9:"ldimporte";s:2:"50";s:7:"ldtotal";s:2:"50";}}s:3:"lte";i:200;s:3:"ltd";i:50;s:10:"ltgtosefec";d:93,66;s:3:"lrl";d:56,34;}';
var_dump(unserialize($ser));
?>

With PHP 4.1.1

array(5) {
  ["lineas"]=>
  array(1) {
    [0]=>
    array(7) {
      ["ldivisa"]=>
      string(3) "eur"
      ["letcambio"]=>
      string(1) "1"
      ["leimporte"]=>
      string(3) "200"
      ["letotal"]=>
      string(3) "200"
      ["ldtcambio"]=>
      string(1) "1"
      ["ldimporte"]=>
      string(2) "50"
      ["ldtotal"]=>
      string(2) "50"
    }
  }
  ["lte"]=>
  int(200)
  ["ltd"]=>
  int(50)
  ["ltgtosefec"]=>
  float(93)
  ["lrl"]=>
  float(56)
}

With PHP 4.2.1

I guess that there is some problem with perhaps the locale, storing "99,33" (spanish decimal) as a float, the same with "56,34", so the problem is perhaps serialize instead. I'll try to give more info.

Ok, I found the problem. See that script:

<?php
error_reporting(E_ALL);
//setlocale(LC_ALL, "es_ES");
$a = 2.3;
$b = serialize($a);
var_dump(serialize($b));
var_dump(unserialize($b));
?>

The output is:
string(13) "s:6:"d:2.3;";"
float(2.3)

No problem. Now uncomment line 2. You'll get:
string(13) "s:6:"d:2,3;";"

Let's assign this to Hartmut, he's busy with all those locale problems.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
