<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>
|
|
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.

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.
