During the years before the release of PHP 5.3 and 5.4, some books were published based on
the expected feature set of PHP 6.0, including both the Unicode work and the features which
were later backported to other releases. There is therefore some debate over whether a new
major version of PHP, with or without Unicode support, should be called "PHP 6", or if the version
should be skipped to avoid confusion.

Beginning on June 28, 2011, the PHP Group began following a timeline for when new versions of
PHP will be released.[44]
Under this timeline, at least one release should occur every month. Once
per year, a minor release should occur which can include new features. Every minor release
should at least have 2 years of security and bug fixes, followed by at least 1 year of only security
fixes, for a total of a 3 year release process for every minor release. No new features (unless
small and self-contained) will be introduced into a minor release during the 3-year release
process.
Syntax[edit]
Main article:PHP syntax and semantics
eased.[19][20]
On July 13, 2004, PHP 5 was released, powered by the new Zend Engine II.[6]
PHP 5 included
new features such as improved support forobject-oriented programming,the PHP Data Objects
(PDO) extension (which defines a lightweight and consistent interface for accessing databases),
and numerous performance enhancements.[21]
In 2008 PHP 5 became the only stable version
under development.Late static bindinghad been missing from PHP and was added in version
5.3.[22][23]
Many high-profile open-source projects ceased to support PHP 4 in new code as of February 5,
2008, because of the GoPHP5 initiative,[24]
provided by a consortium of PHP developers
promoting the transition from PHP 4 to PHP 5.[25][26]
PHP interpreters are available on most existing32-bitand64-bitoperating systems, either by
building them from the PHP source code, or by using pre-built binaries.[27]
For the PHP versions
5.3 and 5.4, the only availableMicrosoft Windowsbinary distributions were 32-
bitx86builds,[28][29]
requiring Windows 32-bit compatibility mode while usingInternet Information
Services(IIS) on a 64-bit Windows platform. PHP version 5.5 made the 64-bitx86-64builds
available for Microsoft Windows.[30]
PHP 6 and Unicode[edit]
PHP received mixed reviews due to lacking nativeUnicodesupport at the core language
level.[31][32]
In 2005, a project headed by Andrei Zmievski was initiated to bring native Unicode
support throughout PHP, by embedding theInternational Components for Unicode(ICU) library,
and representing text strings asUTF-16internally.[33]
Since this would cause major changes both
to the internals of the language and to user code, it was planned to release this as version 6.0 of
the language, along with other major features then in development.[34]
However, a shortage of developers who understood the necessary changes, and performance
problems arising from conversion to and from UTF-16, which is rarely used in a web context, led
to delays in the project.[35]
As a result, a PHP 5.3 release was created in 2009, with many non-

Unicode features back-ported from PHP 6, notably namespaces. In March 2010, the project in its
current form was officially abandoned, and a PHP 5.4 release was prepared containing most
remaining non-Unicode features from PHP 6, such as traits and closure re-binding.[36]
Initial
hopes were that a new plan would be formed for Unicode integration, but as of 2014 none has
been adopted.
During the years before the release of PHP 5.3 and 5.4, some books were published based on
the expected feature set of PHP 6.0, including both the Unicode work and the features which
were later backported to other releases. There is therefore some debate over whether a new
major version of PHP, with or without Unicode support, should be called "PHP 6", or if the version
should be skipped to avoid confusion.

Many high-profile open-source projects ceased to support PHP 4 in new code as of February 5,
2008, because of the GoPHP5 initiative,[24]
provided by a consortium of PHP developers
promoting the transition from PHP 4 to PHP 5.[25][26]
PHP interpreters are available on most existing32-bitand64-bitoperating systems, either bybuilding them from the PHP source code, or by using pre-built binaries.

5.3 and 5.4, the only availableMicrosoft Windowsbinary distributions were 32-
bitx86builds,[28][29]
requiring Windows 32-bit compatibility mode while usingInternet Information
Services(IIS) on a 64-bit Windows platform. PHP version 5.5 made the 64-bitx86-64builds
available for Microsoft Windows.[30]
PHP 6 and Unicode[edit]
PHP received mixed reviews due to lacking nativeUnicodesupport at the core language
level.[31][32]
In 2005, a project headed by Andrei Zmievski was initiated to bring native Unicode
support throughout PHP, by embedding theInternational Components for Unicode(ICU) library,
and representing text strings asUTF-16internally.[33]
Since this would cause major changes both
to the internals of the language and to user code, it was planned to release this as version 6.0 of
the language, along with other major features then in development.[34]
However, a shortage of developers who understood the necessary changes, and performance
problems arising from conversion to and from UTF-16, which is rarely used in a web context, led
to delays in the project.[35]
As a result, a PHP 5.3 release was created in 2009, with many non-
Unicode features back-ported from PHP 6, notably namespaces. In March 2010, the project in its
current form was officially abandoned, and a PHP 5.4 release was prepared containing most
remaining non-Unicode features from PHP 6, such as traits and closure re-binding.[36]
Initial
hopes were that a new plan would be formed for Unicode integration, but as of 2014 none has
been adopted.
During the years before the release of PHP 5.3 and 5.4, some books were published based on
the expected feature set of PHP 6.0, including both the Unicode work and the features whichwere later backported to other releases. There is therefore some debate over whether a new
major version of PHP, with or without Unicode support, should be called "PHP 6", or if the version
should be skipped to avoid confusion.

Beginning on June 28, 2011, the PHP Group began following a timeline for when new versions of
PHP will be released.[44]
Under this timeline, at least one release should occur every month. Once
per year, a minor release should occur which can include new features. Every minor release
should at least have 2 years of security and bug fixes, followed by at least 1 year of only security
fixes, for a total of a 3 year release process for every minor release. No new features (unless
small and self-contained) will be introduced into a minor release during the 3-year release
process.
