<para>
Migrating from PHP 4 to PHP 5
</para>
</question>
<answer>
<para>
Although PHP 5 offers many new features, it's designed to be as
compatible with earlier versions of PHP as possible with little
functionality being broken in the process.
</para>
<para>
Be sure to read the appropriate <link linkend="migration5">PHP 5
migration appendix</link> of this manual as it contains even more
information on the topic of migrating to PHP 5.
</para>

<qandaentry id="faq.migration5.mysql">
<question>
<para>
Does MySQL work in PHP 5? It seemed to have disappeared.
</para>
</question>
<answer>
<para>
<link linkend="ref.mysql">MySQL</link> is supported with the only
change being that MySQL support is no longer enabled by
<emphasis>default</emphasis> in PHP 5. This essentially means that
PHP doesn't include <literal>--with-mysql</literal> in the
<link linkend="configuration">configure</link> line so that you must
now manually do this when compiling PHP. Windows users will
edit &php.ini; and enable the <filename>php_mysql.dll</filename> DLL as
in PHP 4 no such DLL existed, it was simply built into your Windows
PHP binaries.
</para>
<para>
Also, the MySQL client libraries are no longer bundled with PHP. More
details on this topic are covered in
<link linkend="faq.databases.mysql.php5">the following FAQ</link> and
be sure to read the <link linkend="ref.mysql">MySQL section</link>
for details on installing MySQL. An example configure line would be
<literal>--with-mysql=/usr</literal> while Windows users will need
the <filename>libmySQL.dll</filename> available to the system.
</para>
</answer>
</qandaentry>
<qandaentry id="faq.migration5.oop">
<question>
<para>
I hear PHP 5 has an entirely new OOP model, will my existing OOP code
work? Where do I find information on these new OOP features?
</para>
</question>
<answer>
<para>
The main change in PHP 5 is to the OOP model as PHP 5 now uses
the <emphasis>Zend Engine 2.0</emphasis>. The <link
linkend="ini.zend.ze1-compatibility-mode">
zend.ze1_compatibility_mode</link> directive enables compatability
with the Zend Engine 1.0 (PHP 4).
</para>
<para>
The new OOP model is documented in the <link linkend="language.oop5">
OOP language reference</link> and <link linkend="migration5.oop">OOP
migration appendix</link> sections.
</para>
</answer>
</qandaentry>
<qandaentry id="faq.migration5.changes">
<question>
<para>
So besides the new OOP model, what else has changed in PHP 5? Also, is
there a PHP 5 specific version of the PHP manual?
</para>
</question>
<answer>
<para>
Few other changes exist, see the <link linkend="migration5">migration
5 appendix</link> for details. There won't be a PHP 5 specific
version of the manual as the bulk of PHP remains the same.
