    Le seguenti modifiche sono state apportate alle funzioni delle estensioni del pacchetto.

    VersionFunctionDescription
    PHP 5.2.2DOMDocument::registerNodeClassPrior to 5.2.2, a previously registered extendedclass had to be unregistered before being able to register a new class extending the same baseclass.
    7.0.0ob_startIn case ob_start is used inside an output buffer callback, this function will no longer issue an E_ERROR but instead an E_RECOVERABLE_ERROR, allowing custom error handlers to catch such errors.
    6error_reportingE_STRICT è diventata parte di E_ALL.
    5.6.3packThe "q", "Q", "J" and "P" codes were added to enable working with 64-bit numbers.
    5.6.0hash_algosSupport for gost-crypto was added. This implements the GOST hash function using the CryptoPro S-box tables as specified by RFC 4357, section 11.2.
     json_decodeInvalid non-lowercased variants of the true, false and null literals are no longer accepted as valid input, and will generate warnings.
     mb_regex_encodingDefault encoding is changed to UTF-8. It was EUC-JP Previously.
     mcrypt_create_ivMCRYPT_DEV_URANDOM is now the default value of source.
     mcrypt_decryptInvalid key and iv sizes are no longer accepted. mcrypt_decrypt will now throw a warning and return FALSE if the inputs are invalid. Previously keys and IVs were padded with '\0' bytes to the next valid size.
     mcrypt_encryptInvalid key and iv sizes are no longer accepted. mcrypt_encrypt will now throw a warning and return FALSE if the inputs are invalid. Previously keys and IVs were padded with '\0' bytes to the next valid size.
     pg_lo_truncateAdded truncate function. It supports PostgreSQL 9.3's 64bit large object. Both client and server must support PostgreSQL 9.3 and PHP must be 64bit build to use 64bit large object.
     stream_socket_enable_cryptoThe crypto_type is now optional.
     ReflectionClass::newInstanceWithoutConstructorAll internal classes can now be instantiated except for those declared final.
     XMLReader::getAttributeNoXMLReader::getAttributeNo now returns NULL if the attribute doesn't exist.
     XMLReader::getAttributeNsXMLReader::getAttributeNS now returns NULL if the attribute doesn't exist.
    5.5.19/5.6.3imagescaleThe calculation of the height if new_height was negative or omitted was fixed; prior to these versions, the aspect ratio was not maintained correctly.

    5.5.2DOMDocument::schemaValidateAdded the flags parameter
     DOMDocument::schemaValidateSourceAdded the flags parameter

    5.5.0/PECL 3.0.0IntlDateFormatter::createAn IntlCalendar object is allowed for calendar. Objects of type IntlTimeZone and DateTimeZone are allowed for timezone. Invalid timezone identifiers (including empty strings) are no longer allowed for timezone. If NULL is given for timezone, the timezone identifier given by date_default_timezone_get will be used instead of ICUʼs default.
     IntlDateFormatter::formatSupport for providing IntlCalendar objects to the value parameter was added.
     IntlDateFormatter::setCalendarIt became possible to pass an IntlCalendar object.
    5.5.0DatePeriod::__constructstart type changed to DateTimeImmutable. Previously, DateTime.

     iterator_to_arrayiterator_to_array gained support for key types other than integer and string when the use_keys parameter is enabled.
     json_encodedepth parameter was added.
     packThe "Z" code was added with equivalent functionality to "a" for Perl compatibility.
     setcookieA Max-Age attribute is now included in the Set-Cookie header sent to the client.
     setrawcookieA Max-Age attribute is now included in the Set-Cookie header sent to the client.
     unpackChanges were made to bring this function into line with Perl: The "a" code now retains trailing NULL bytes. The "A" code now strips all trailing ASCII whitespace (spaces, tabs, newlines, carriage returns, and NULL bytes). The "Z" code was added for NULL-padded strings, and removes trailing NULL bytes.
     mysqli::commitAdded flags and name parameters.
     mysqli::optionsThe MYSQLI_SERVER_PUBLIC_KEY option was added.
     mysqli::rollbackAdded flags and name parameters.
     SoapClient::SoapClientNew ssl_method option.

    5.4.0/PECL 2.0.0b1idn_to_asciiAdded the parameters variant and idna_info; UTS #46 support.
     idn_to_utf8Added the parameters variant and idna_info; UTS #46 support.
    5.4.0DOMDocument::loadHTMLAdded options parameter.
     DOMDocument::loadHTMLFileAdded options parameter.
     apache_child_terminateQuesta funzione diventa disponibile sotto FastCGI. Precedentemente, era supportata solo quando PHP era installato come modulo Apache.

     date_default_timezone_getThe TZ environment variable is no longer used to guess the timezone.
     date_default_timezone_getThe timezone is no longer guessed from information available through the operating system as the guessed timezone can not be relied on.
     dns_get_recordAdded raw parameter.
     emptyIl controllo su offset non numerici di stringhe restituisce TRUE.
     filter_input_arrayAdded add_empty parameter.
     filter_var_arrayAdded add_empty parameter.

     mb_encode_numericentityAdded is_hex parameter.
     ob_startThe third parameter of ob_start changed from a boolean parameter called erase (which, if set to FALSE, would prevent the output buffer from being deleted until the script finished executing) to an integer parameter called flags. Unfortunately, this results in an API compatibility break for code written prior to PHP 5.4.0 that uses the third parameter. See the flags example for an example of how to handle this with code that needs to be compatible with both.
     ob_startA chunk size of 1 now results in chunks of 1 byte being sent to the output buffer.
     openssl_decryptThe raw_output was changed to options.
     openssl_encryptThe raw_output was changed to options.
     scandirsorting_order constants were added. Any nonzero value caused descending order in previous versions. So for all PHP versions, use 0 for ascending order, and 1 for descending order. An option for SCANDIR_SORT_NONE behavior did not exist prior to PHP 5.4.0.
     snmp_set_valueretrievalConstants SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY may be combined with SNMP_VALUE_OBJECT resulting different way of representing contents of value array element in return value of GET-function. If no SNMP_VALUE_{PLAIN,LIBRARY} constant is accompanying SNMP_VALUE_OBJECT, SNMP_VALUE_LIBRARY is used. Prior to 5.4.0 SNMP_VALUE_OBJECT effecively meant SNMP_VALUE_OBJECT|SNMP_VALUE_PLAIN.
