Deprecated features in PHP 7.0.x

PHP 4 style constructors

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 E_DEPRECATED if a PHP 4 constructor is the only constructor defined within a class. Classes that implement a __construct() method are unaffected.

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

以上例程会输出:

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; foo has a deprecated constructor in example.php on line 3

Static calls to non-static methods

Static calls to methods that are not declared static are deprecated, and may be removed in the future.

<?php
class  foo  {
    function 
bar () {
        echo 
'I am not static!' ;
    }
}

foo :: bar ();
?>

以上例程会输出:

Deprecated: Non-static method foo::bar() should not be called statically in - on line 8
I am not static!

password_hash() salt option

The salt option for the password_hash() 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.

capture_session_meta SSL context option

The capture_session_meta SSL context option has been deprecated. SSL metadata is now available through the stream_get_meta_data() function.
