<title>Other Changes</title>
<sect2 xml:id="migration82.other-changes.core">
<title>Core changes</title>
<para>
The <type>iterable</type> type is now a built-in compile time alias for
<type class="union"><type>array</type><type>Traversable</type></type>.
Error messages relating to <literal>iterable</literal> will therefore
now use <literal>array|Traversable</literal>.
Type Reflection is preserved for single <literal>iterable</literal>
(and <literal>?iterable</literal>) to produce a
<classname>ReflectionNamedType</classname> with name <literal>iterable</literal>,
however usage of <literal>iterable</literal> in union types will be
converted to <literal>array|Traversable</literal>.
</para>
<para>
The date format of sent cookies is now <literal>'D, d M Y H:i:s \G\M\T'</literal>;
previously it was <literal>'D, d-M-Y H:i:s T'</literal>.

<sect3 xml:id="migration82.other-changes.sapi.cli">
<title>CLI</title>
<para>
The STDOUT, STDERR and STDIN streams are no longer closed on resource destruction
which is mostly when the CLI finishes. It is however still possible to
explicitly close those streams using <function>fclose</function> and similar.
</para>

<sect2 xml:id="migration82.other-changes.functions">

<sect3 xml:id="migration82.other-changes.functions.core">
<title>Core</title>
<para>
The <function>strcmp</function>, <function>strcasecmp</function>,
<function>strncmp</function>, <function>strncasecmp</function>, and
<function>substr_compare</function> functions, using binary safe string
comparison is no longer guaranteed to return
<code>strlen($string1) - strlen($string2)</code> when string lengths are not
equal, but may now return <literal>-1</literal> or <literal>1</literal>
instead. Instead of depending on any concrete value, the return value should
be compared to <literal>0</literal>.
</para>
</sect3>
<sect3 xml:id="migration82.other-changes.functions.dba">
<title>DBA</title>
<para>
<function>dba_open</function> and <function>dba_popen</function>
now have the following enforced signature:
<methodsynopsis>
<type class="union"><type>resource</type><type>false</type></type><methodname>dba_open</methodname>
<methodparam><type>string</type><parameter>path</parameter></methodparam>

</methodsynopsis>
</para>
<para>
<function>dba_fetch</function>'s optional skip argument is now at the end
in line with PHP userland semantics. Its signature is now:
<methodsynopsis>
<type class="union"><type>string</type><type>false</type></type><methodname>dba_fetch</methodname>
<methodparam><type class="union"><type>string</type><type>array</type></type><parameter>key</parameter></methodparam>
<methodparam><type>resource</type><parameter>handle</parameter></methodparam>
<methodparam><type>int</type><parameter>skip</parameter></methodparam>
</methodsynopsis>
The overloaded signature:
<methodsynopsis>
<type class="union"><type>string</type><type>false</type></type><methodname>dba_fetch</methodname>
<methodparam><type class="union"><type>string</type><type>array</type></type><parameter>key</parameter></methodparam>
<methodparam><type>int</type><parameter>skip</parameter></methodparam>
<methodparam><type>resource</type><parameter>handle</parameter></methodparam>
</methodsynopsis>
is still accepted, but it is recommended to use the new standard variant.

</sect3>
<sect3 xml:id="migration82.other-changes.functions.random">
<title>Random</title>
<para>
<function>random_bytes</function> and <function>random_int</function>
now throw a <classname>\Random\RandomException</classname> on <acronym>CSPRNG</acronym> failures.
Previously a plain <classname>\Exception</classname> was thrown instead.

<sect3 xml:id="migration82.other-changes.functions.spl">
<title>SPL</title>
<para>
The <parameter>iterator</parameter> parameter of
<function>iterator_to_array</function> and <function>iterator_count</function>
is widened to <type>iterable</type> from <classname>Iterator</classname>,
allowing arrays to be passed.

<sect3 xml:id="migration82.other-changes.extensions.mysqli">
<title>MySQLi</title>
<para>
The support for libmysql has been removed and it is no longer
possible to compile mysqli with libmysql.
From now on, the mysqli extension can be compiled only with mysqlnd.
All libmysql features unavailable in mysqlnd have been removed:
<simplelist>
<member>The reconnect property of <classname>mysqli_driver</classname></member>
<member>
The <link linkend="ini.mysqli.reconnect">mysqli.reconnect</link> INI directive
</member>
<member>The <constant>MYSQLI_IS_MARIADB</constant> constant has been deprecated</member>

<title>Session</title>
<para>
Trying to change the
<link linkend="ini.session.cookie-samesite">session.cookie_samesite</link>
INI directive while the session is active or output has already been sent

This aligns the behaviour with all other session INI settings.

<sect3 xml:id="migration82.other-changes.extensions.tidy">
<title>Tidy</title>
<para>
The properties of the <classname>tidy</classname> class are now properly declared.
And those of the <classname>tidyNode</classname> class are now properly declared as readonly.
</para>
</sect3>
<sect3 xml:id="migration82.other-changes.extensions.zip">
<title>Zip</title>
<para>
The Zip extension has been updated to version 1.20.0,
which adds the following methods:
<simplelist>
<member><methodname>ZipArchive::clearError</methodname></member>
<member><methodname>ZipArchive::getStreamName</methodname></member>
<member><methodname>ZipArchive::getStreamIndex</methodname></member>

<title>Changes to INI File Handling</title>
<!-- Commit: https://github.com/php/php-src/commit/0f8b9eb49bd644f07175e9191d2cc146737446ad -->
<para>
Support for binary (<literal>0b</literal>/<literal>0B</literal>) and octal
(<literal>0o</literal>/<literal>0O</literal>) prefixes has been added to integer INI settings.
Integer INI settings that start with a zero (<literal>0</literal>)
continue to be interpreted as an octal integer.
</para>
<para>
Parsing of some ill-formatted values will now trigger a warning when this
was silently ignored before.
For backwards compatibility, interpretation of these values has not changed.
This affects the following settings:
