I want to have my PHP application labeled with the revision number which it uses, but I don't want to use CruiseControl or update a file and upload it every time. How should I do it?

SVN keywords is not a good solution. As others pointed out adding $Revision$ in a file only affects the specific file, which may not change for a long time.

Remembering to "edit" a file (by adding or removing a blank line) before every commit is pointless. You could as well just type the revision by hand.

One good way to do it (that I know of) is to have an automated deployment process (which is always a good thing) and using the command svnversion. Here is what I do:

Wherever I need the revision I do an include: <?php include 'version.php'; ?>. This "version.php" file only has the revision number. Moreover it is not part of the repository (it set to be ignored). Here is how I create it:

1) On projects where SVN is installed on the server, I also use it for deployment. Getting the latest version to the server I have a script that among other things does the following (it runs on the server):

cd /var/www/project
svn update
rm version.php
svnversion > version.php

2) On projects where SVN is not installed my deployment script is more complex: it creates the version.php file locally, zips the code, uploads and extracts it

// first : get all data, if the data same / duplicate take only one data

$unique = array_unique($data, SORT_REGULAR);

// then, get the data which duplicate with

$diffCellUniq = array_diff_key($data, $unique);

// so print the result

print_r($diffCellUniq); exit;

Array
(
    [2] => Array
        (
            [a] => 1
            [b] => 2
            [c] => 3
            [d] => 4
        )

Actually question in my head includes deleting a node as well , mistakenly i could not add it. So in my point of view this is the complete answer, i a case if someone else find this useful. This answer doesn't include SimpleXMLElement class because how hard i tried it didn't delete the node with unset(); . So back to where i was , i finally found an answer. This is my code. and its Simple!!!

if(file_exists($xmlfile)){
              $doc = new DOMDocument();
              $doc->load($xmlfile);
              $presetgroup = $doc->getElementsByTagName( "preset" );
              foreach($presetgroup as $group){       
                 $pname = $group->getElementsByTagName( "name" );
                  $pcode = $pname->item(0)->getAttribute('code');
                 if($pcode==$preset_name){
                      echo($preset_name);
                      $group->parentNode->removeChild($group);
                 }
              }
          }
        $doc->save($xmlfile);

You could use svn log, with a reverse revision range:

svn log -r 1:HEAD --limit 1 <REPO_URL>

VCS systems are designed specifically to make this as complicated as possible. You usually do not want to do this.

That being said, from the official documentation:

There are special cases where you might want to destroy all evidence of a file or commit. (Perhaps somebody accidentally committed a confidential document.) This isn't so easy, because Subversion is deliberately designed to never lose information. Revisions are immutable trees which build upon one another. Removing a revision from history would cause a domino effect, creating chaos in all subsequent revisions and possibly invalidating all working copies.

The project has plans, however, to someday implement an svnadmin obliterate command which would accomplish the task of permanently deleting information. (See issue 516.)

In the meantime, your only recourse is to svnadmin dump your repository, then pipe the dumpfile through svndumpfilter (excluding the bad path) into an svnadmin load command. See chapter 5 of the Subversion book for details about this.
