====== PHP/Installing_SVN_Extension ======

=====Installation=====
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 <code>apr.h</code>.  [[http://pecl.php.net/bugs/bug.php?id=10811&edit=1|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, [[http://uk3.php.net/manual/en/function.svn-log.php|like the documentation suggests it should]].  This was [[http://cvs.php.net/viewvc.cgi/pecl/svn/svn.c?r1=1.35&r2=1.36|broken a mere 2 weeks before the 0.3 release]], and [[http://cvs.php.net/viewvc.cgi/pecl/svn/svn.c?r1=1.47&r2=1.48|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

=====Other Notes=====
The PHP docs haven't been updated with information about the latest builds.
====svn_log()====
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 <code>$flags</code> argument is a bitwise value that lets you change the output.  Available flags, including their corresponding <code>svn</code> 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>**.

====Constants====
 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)
