<h1>PHP 5 ChangeLog</h1>

<a name="5.0.0b4"></a>
<h3>Version 5.0.0 Beta 4</h3>
<b>12-Feb-2004</b>
<ul>
<li>Changed exceptions so that they must now inherit from the built-in Exception
class. This allows for a general catch(Exception $e) statement to catch all
exceptions. (Andi, Zeev)</li>
<li>Added SPL extension. (Marcus, Derick)</li>
<li>Added checks for invalid characters in a cookie name and cookie data
into set[raw]cookie(). (Brian)</li>
<li>Added support for ++ and += (and similar) to SimpleXML. (Andi, Zeev)</li>
<li>Added infrastructure for ++ and += (and similar) to object overloading
modules. (Andi, Zeev)</li>
<li>Added error message when trying to re-assign to $this variable. (Zeev, Andi)</li>
<li>Added support for an interface to extend another interface. (Zeev)</li>
<li>Added new pspell functions: (Brian)</li>
  <ul>
    <li>pspell_config_dict_dir()</li>
    <li>pspell_config_data_dir()</li>
  </ul>
<li>Added new Interbase functions: (Ard)</li>
  <ul>
    <li>ibase_service_attach() and ibase_service_detach().</li>
    <li>ibase_backup() and ibase_restore().</li>
    <li>ibase_maintain_db(), ibase_db_info() and ibase_server_info().</li>
  </ul>
<li>Added context option "http"/"request_fulluri" to send entire URI in request
which is required format for some proxies. (Sara)</li>
<li>Added optional third parameter 'strict' to array_keys(). (Andrey)</li>

features such as interfaces. (Zeev, Andi)</li>

<li>Upgraded bundled SQLite library to version 2.8.11. (Ilia, Wez)</li>

shutdown. An order of destruction is not guaranteed. (Zeev, Andi)</li>

such as nested try's and problems with overloaded extensions. (Zeev, Andi)</li>

properties before __clone() is called. Also allows calling parent __clone
function by using parent::__clone(). (Zeev, Andi)</li>

inheriting and implementing interfaces. (Andi, Zeev)</li>
