The first one is support for Perl-style matching regexp delimiters, i.e.
using <[{( and )}]> to delimit the regular expressions.
The second one is a new 'F' modifier that allows you to specify a function name
in the replacement argument to preg_replace(). This function will be called
when the replacement needs to be made. It is passed an array of full matched
pattern and captured subpatterns and it is expected to return a string that
will be used for replacement. 'e' and 'F' modifiers cannot be used together.
@- Implemented support for Perl-style matching regexp delimiters in PCRE.
@ You can use <{[( and )]}> to delimit your expressions now. (Andrei)
@- Introduced new 'F' modifier in PCRE that lets you specify a function
@ name in the replacement argument to preg_replace() that will be called
@ at run-time to provide the replacement string. It is passed an array of
@ matched pattern and subpatterns. (Andrei)
I happen to think that this is php_addslashes() problem, not PCRE's.
When 0 is passed for the length of the string to php_addslashes() it
assumes that we want to process the whole string and happily runs
strlen() on it. That is bad. It should respect the length and return
an empty string if it's 0.
Draft 3 of IEEE 1003.1 200x, "2.2 The Compilation Environment"
All identifiers that begin with an underscore and either an uppercase
letter or another underscore are always reserved for any use by the
implementation.
The following new/revived shared modules are available now:
... MySQL (*)
... PCRE (*)
... Session
... SWF
(*) capable of using bundled library or external library
All changes:
The m4 macro PHP_EXTENSION was revamped. Uses LIB_BUILD now.
This effectively means that all extensions have to use dynlib.
ext/mysql/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/pcre/config.m4 was revamped.
Uses LIB_BUILD for building bundled library.
ext/ext_skel was changed to reflect that more modules should be
compileable as shared module.
ext/Makefile.in has been simplified enormously.
Dependencies are now stored in the build tree.
Empty dependencies are not generated by buildconf anymore. They
are now dynamically created during the build process.
Implicit rules for .S were removed.
The NO_RECURSION feature was removed.
"libs.mk" has been added to all cvsignore files in ext.
* Makefile header is now completely dynamic
* Absolute paths in (top_)?(src|build)dir and VPATH
(fixes Tru64 support)
* VPATH does not contain variables anymore
(fixes UnixWare support)
