<sect2 xml:id="migration70.deprecated.php4-constructors">
<title>PHP 4 style constructors</title>
<para>
PHP 4 style constructors (methods that have the same name as the class they
are defined in) are deprecated, and will be removed in the future. PHP 7
will emit <constant>E_DEPRECATED</constant> if a PHP 4 constructor is the
only constructor defined within a class. Classes that implement a
<function>__construct</function> method are unaffected.
</para>

<programlisting role="php">

<?php
class foo {
function foo() {
echo 'I am the constructor';
}
}
?>
]]>

<sect2 xml:id="migration70.deprecated.pwshash-salt-option">
<title><function>password_hash</function> salt option</title>
<para>
The salt option for the <function>password_hash</function> function has been
deprecated to prevent developers from generating their own (usually insecure)
salts. The function itself generates a cryptographically secure salt when no
salt is provided by the developer - therefore custom salt generation should not
be needed.
</para>

<sect2 xml:id="migration70.deprecated.capture-session-meta">
<title><literal>capture_session_meta</literal> SSL context option</title>
<para>
The <literal>capture_session_meta</literal> SSL context option has been
deprecated. SSL metadata is now available through the
<function>stream_get_meta_data</function> function.
