PHP Manual: Deprecated Features

PHP Core

Saner Increment/Decrement operators

Using the increment operator (++) on empty, non-numeric, or non-alphanumeric strings is now deprecated. Moreover, incrementing non-numeric strings is soft deprecated. That means no E_DEPRECATED diagnostic is emitted, but this feature should not be used when producing new code. The new str_increment() function should be used instead.

Using the decrement operator (--) on empty or non-numeric strings is now deprecated.

get_class()/get_parent_class() call without arguments

Calling get_class() and get_parent_class() without arguments is now deprecated.

DBA

Calling dba_fetch() with dba as the 3rd argument is now deprecated.

FFI

Calling FFI::cast(), FFI::new(), and FFI::type() statically is now deprecated.

Intl

The U_MULTIPLE_DECIMAL_SEP*E*RATORS constant had been deprecated, using the U_MULTIPLE_DECIMAL_SEP*A*RATORS constant instead is recommended.

The NumberFormatter::TYPE_CURRENCY constant has been deprecated.

LDAP

Calling ldap_connect() with separate hostname and port is deprecated.

MBString

Passing a negative width to mb_strimwidth() is now deprecated.

Phar

Calling Phar::setStub() with a resource and a length is now deprecated. Such calls should be replaced by: $phar->setStub(stream_get_contents($resource));

Random

The MT_RAND_PHP Mt19937 variant is deprecated.

Reflection

Calling ReflectionProperty::setValue() with only one parameter is deprecated. To set static properties, pass null as the first parameter.

The ASSERT_ACTIVE, ASSERT_BAIL, ASSERT_CALLBACK, ASSERT_EXCEPTION, and ASSERT_WARNING constants have been deprecated.
