Deprecated features in PHP 7

Even though PHP 7.0 is a new major version, efforts have been made to make migration as painless as possible. This release focuses mainly on removing functionality deprecated in previous versions and improving language consistency.

PHP 4 style constructors

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

The above example will output:

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();
?>

The above example will output:

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.

LDAP deprecations

The following function has been deprecated:
1. ldap_sort()
