Apache2Handler

The PHP module has been renamed from php7_module to php_module.

Reflection

ReflectionClass::getConstants and ReflectionClass::getReflectionConstants results can be now filtered via a new parameter filter. Three new constants were added to be used with it:

• ReflectionClassConstant::IS_PUBLIC
• ReflectionClassConstant::IS_PROTECTED
• ReflectionClassConstant::IS_PRIVATE

Standard

The math functions abs, ceil, floor and round now properly heed the strict_types directive. Previously, they coerced the first argument even in strict type mode.

Zip

• The ZipArchive::addGlob and ZipArchive::addPattern methods accept more values in the options array argument:

  • flags
  • comp_method
  • comp_flags
  • env_method
  • enc_password

• ZipArchive::addEmptyDir, ZipArchive::addFile and ZipArchive::addFromString methods have a new flags argument. This allows managing name encoding (ZipArchive::FL_ENC_*) and entry replacement (ZipArchive::FL_OVERWRITE).

• ZipArchive::extractTo now restores the file modification time.

CURL

• The CURL extension now requires at least libcurl 7.29.0.

• The deprecated parameter version of curl_version has been removed.

Date and Time

DatePeriod now implements IteratorAggregate (instead of Traversable).

DOM

DOMNamedNodeMap and DOMNodeList now implement IteratorAggregate (instead of Traversable).

Intl

IntlBreakIterator and ResourceBundle now implement IteratorAggregate (instead of Traversable).

Enchant

The enchant extension now uses libenchant-2 by default when available. libenchant version 1 is still supported but is deprecated and could be removed in the future.

GD

• The num_points parameter of imagepolygon, imageopenpolygon and imagefilledpolygon is now optional, i.e. these functions may be called with either 3 or 4 arguments. If the argument is omitted, it is calculated as count($points)/2.

• The function imagegetinterpolation to get the current interpolation method has been added.

JSON

The JSON extension cannot be disabled anymore and is always an integral part of any PHP build, similar to the date extension.

MBString

The Unicode data tables have been updated to version 13.0.0.

PDO

PDOStatement now implements IteratorAggregate (instead of Traversable).

LibXML

The minimum required libxml version is now 2.9.0. This means that external entity loading is now guaranteed to be disabled by default, and no extra steps need to be taken to protect against XXE attacks.

MySQLi / PDO MySQL

• When mysqlnd is not used (which is the default and recommended option), the minimum supported libmysqlclient version is now 5.5.

• mysqli_result now implements IteratorAggregate (instead of Traversable).

PGSQL / PDO PGSQL

The PGSQL and PDO PGSQL extensions now require at least libpq 9.1.

Readline

Calling readline_completion_function before the interactive prompt starts (e.g. in auto_prepend_file) will now override the default interactive prompt completion function. Previously, readline_completion_function only worked when called after starting the interactive prompt.

SimpleXML

SimpleXMLElement now implements RecursiveIterator and absorbed the functionality of SimpleXMLIterator. SimpleXMLIterator is an empty extension of SimpleXMLElement.
