The latest release of the SVN extension for PHP is 0.3, however various versions have some pretty major bugs:

• 0.2 won't install on Ubuntu. It complains during compilation that it can't find

  apr.h

  . This was fixed in version 0.3.

• 0.3 has a bug in the svn_log() function that prevents it returning an array of changed paths for each revision, like the documentation suggests it should. This was broken a mere 2 weeks before the 0.3 release, and fixed about a month after the release.

Since 0.2 and 0.3 are unusable (and I don't want to consider 0.1), you'll have to install the latest CVS version instead.

• First, get some pre-requisites:

sudo apt-get install libsvn1 libsvn-dev php5-dev build-essential

• Then get the CVS HEAD revision and change into the directory it creates:

cvs -d:pserver:cvsread@cvs.php.net:/repository co pecl/svn cd pecl/svn

• Install it with PECL:

sudo pecl install package2.xml

• Add the “extension” line to your php.ini file:

sudo echo “extension=svn.so” » /etc/php5/apache2/php.ini

• And reload Apache:

sudo /etc/init.d/apache2 force-reload

The PHP docs haven't been updated with information about the latest builds.

Function prototype is now: array svn_log ( string $repos_url [, int $start_revision=HEAD [, int $end_revision=INITIAL [, int $limit [, int $flags ]]]]) Meaning that the results of this function are no longer either all revisions or a single revision.

The

$flags

argument is a bitwise value that lets you change the output. Available flags, including their corresponding

svn

command-line switches, as stated in the extension's source are: SVN_NON_RECURSIVE (–non-recursive) SVN_DISCOVER_CHANGED_PATHS (–verbose) SVN_OMIT_MESSAGES (–quiet) SVN_STOP_ON_COPY (–stop-on-copy) SVN_ALL (–verbose in svn status) SVN_SHOW_UPDATES (–show-updates) SVN_NO_IGNORE (–no-ignore) The default is currently <code>SVN_DISCOVER_CHANGED_PATHS | SVN_STOP_ON_COPY</code>, so to stop it returning the changed paths, for example, pass <code>SVN_STOP_ON_COPY</code>, or to disable all flags entirely just pass <code>0</code>.

SVN_REVISION_HEAD (Pass to functions expecting a revision number and the HEAD revision will be used instead) SVN_REVISION_INITIAL (Pass to functions expecting a revision number and the initial revision will be used instead)
