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';
}
}
?>
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.
