Following features are deprecated and may be removed from future releases of PHP.
PHP 4 style constructors
PHP 4 style Constructors are methods having same name as the class they are defined in, are now 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 implementing a __construct() method are unaffected.
Example
<?php class A { function A() { print('Style Constructor'); } } ?>
It produces the following browser output −
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; A has a deprecated constructor in...
Static calls to non-static methods
Static calls to non-static methods are deprecated, and may be removed in the future.
Example
<?php class A { function b() { print('Non-static call'); } } A::b(); ?>
It produces the following browser output −
Deprecated: Non-static method A::b() should not be called statically in... Non-static call
password_hash() salt option
The salt option for the password_hash() function has been deprecated so that the developers do not generate their own (usually insecure) salts. The function itself generates a cryptographically secure salt, when no salt is provided by the developer - thus custom salt generation is not required any more.
capture_session_meta SSL context option
The capture_session_meta SSL context option has been deprecated. SSL metadata is now used through the stream_get_meta_data() function.
