Trying to produce output (e.g. with echo) within a user output handler is deprecated. The deprecation warning will bypass the handler producing the output to ensure it is visible; if there are nested output handlers the next one will still be used. Non-canonical cast names (boolean), (integer), (double), and (binary) have been deprecated, use (bool), (int), (float), and (string) respectively. Terminating case statements with a semicolon instead of a colon has been deprecated. The backtick operator as an alias for shell_exec has been deprecated. Returning &null; from __debugInfo() has been deprecated. Return an empty array instead. The report_memleaks INI directive has been deprecated. Constant redeclaration has been deprecated. Note that this already generated a warning and will continue to do so. The following closure binding issues, which already emit an E_WARNING, are now deprecated: Binding an instance to a static closure. Binding methods to objects that are not instances of the class (or subclass) that the method is defined. Unbinding $this from a method. Unbinding $this from a closure that uses `$this`. Binding a closure to the scope of an internal class. Rebinding the scope of a closure created from a function or method. The __sleep() and __wakeup() magic methods have been soft-deprecated. The __serialize() and __unserialize() magic methods should be used instead, or at the same time if compatibility with PHP 7 is required. Using &null; as an array offset or when calling array_key_exists is now deprecated. Instead an empty string should be used. Incrementing non-numeric strings is now deprecated. Instead the str_increment function should be used. Deriving $_SERVER['argc'] and $_SERVER['argv'] from the query string for non-CLI SAPIs has been deprecated. Configure register_argc_argv=0 and switch to either $_GET or $_SERVER['QUERY_STRING'] to access the information, after verifying that the usage is safe. The curl_close function has been deprecated, as CurlHandle objects are freed automatically. The curl_share_close function has been deprecated, as CurlShareHandle objects are freed automatically. The DATE_RFC7231 and DateTimeInterface::RFC7231 constants have been deprecated. This is because the associated timezone is ignored and always uses GMT. The finfo_close function has been deprecated. As finfo objects are freed automatically. The context parameter of the finfo_buffer function has been deprecated as it is ignored. The imagedestroy function has been deprecated, as GdImage objects are freed automatically. The MHASH_* constants have been deprecated. The intl.error_level INI setting has been deprecated. Errors should either be checked manually or exceptions should be enabled by using the intl.use_exceptions INI setting. Specific Oracle Instant Client calls and constants have been deprecated. List of affected calls: ldap_connect with wallet support ldap_connect_wallet List of affected constants: GSLC_SSL_NO_UATH GSLC_SSL_ONEWAY_UATH GSLC_SSL_TWOWAY_UATH The mysqli_execute alias function has been deprecated. Use mysqli_stmt_execute instead. The key_length parameter for openssl_pkey_derive has been deprecated. This is because it is either ignored, or truncates the key, which can be a security vulnerability. The "uri:" DSN scheme has been deprecated due to security concerns with DSNs coming from remote URIs. Driver specific constants in the PDO class have been deprecated.

Calling ReflectionClass::getConstant for constants that do not exist has been deprecated. Calling ReflectionProperty::getDefaultValue for properties without default values has been deprecated. Unregistering all autoloaders by passing the spl_autoload_call function as a callback argument to spl_autoload_unregister has been deprecated. Instead if this is needed, one should iterate over the return value of spl_autoload_functions and call spl_autoload_unregister on each value. The SplObjectStorage::contains, SplObjectStorage::attach, and SplObjectStorage::detach methods have been deprecated in favour of SplObjectStorage::offsetExists, SplObjectStorage::offsetSet, and SplObjectStorage::offsetUnset respectively. Using ArrayObject and ArrayIterator with objects has been deprecated. The socket_set_timeout alias function has been deprecated. Use stream_set_timeout instead. Passing &null; to readdir, rewinddir, and closedir to use the last opened directory has been deprecated. Provide the last opened directory explicitly instead. Passing integers outside the interval [0, 255] to chr is now deprecated. This is because a byte can only hold a value within this interval. Passing a string which is not a single byte to ord is now deprecated, this is indicative of a bug. The locally predefined variable $http_response_header is deprecated. Instead one should call the http_get_last_response_headers function. The xml_parser_free function has been deprecated, as XMLParser objects are freed automatically.
