<title>PHP Core</title>
<sect3 xml:id="migration73.deprecated.core.ci-constant">
<title>Case-Insensitive Constants</title>
<para>
The declaration of case-insensitive constants has been deprecated. Passing
&true; as the third argument to <function>define</function> will now generate a
deprecation warning. The use of case-insensitive constants with a case that
differs from the declaration is also deprecated.
</para>
</sect3>
<sect3 xml:id="migration73.deprecated.core.assert">
<title>Namespaced assert()</title>
<para>
Declaring a function called <literal>assert()</literal> inside a namespace is
deprecated. The <function>assert</function> function is subject to special
handling by the engine, which may lead to inconsistent behavior when defining
a namespaced function with the same name.
</para>
</sect3>
<sect3 xml:id="migration73.deprecated.core.string-search">
<title>Searching Strings for non-string Needle</title>
<para>
Passing a non-string needle to string search functions is deprecated. In the
future the needle will be interpreted as a string instead of an ASCII
codepoint. Depending on the intended behavior, you should either explicitly
cast the needle to string or perform an explicit call to
<function>chr</function>. The following functions are affected:
<itemizedlist>

<simpara><function>strpos</function></simpara>

<sect3 xml:id="migration73.deprecated.core.strip-tags-streaming">
<title>Strip-Tags Streaming</title>
<para>
The <function>fgetss</function> function and the <link
linkend="filters.string">string.strip_tags stream filter</link> have been
deprecated. This also affects the
<methodname>SplFileObject::fgetss</methodname>
method and <function>gzgetss</function> function.
</para>
</sect3>
</sect2>
<sect2 xml:id="migration73.deprecated.filter">
<title>Data Filtering</title>
<para>
The explicit usage of the constants
<constant>FILTER_FLAG_SCHEME_REQUIRED</constant> and
<constant>FILTER_FLAG_HOST_REQUIRED</constant> is now deprecated; both are
implied for <constant>FILTER_VALIDATE_URL</constant> anyway.
</para>
</sect2>
<sect2 xml:id="migration73.deprecated.image">
<title>Image Processing and GD</title>
<para>
<function>image2wbmp</function> has been deprecated.
</para>

<sect2 xml:id="migration72.deprecated.intl">
<title>Internationalization Functions</title>
<para>
Usage of the <constant>Normalizer::NONE</constant> form throws a deprecation
warning, if PHP is linked with ICU ≥ 56.
</para>
</sect2>
<sect2 xml:id="migration73.deprecated.mbstring">
<title>Multibyte String</title>
<para>
The following undocumented <literal>mbereg_*()</literal> aliases have been
deprecated. Use the corresponding <literal>mb_ereg_*()</literal> variants
instead.
