Example #1 Basic example
This example retrieves the contents of a file at revision 28:
<?php
$contents = svn_cat('http://www.example.com/svnroot/calc/gui.c', 28)
?>
Just to add to Adam's comment, when retrieving a file contents I found I got the best results using the same revision in both places every time; ie. as follows:
<?php
svn_cat ($url.'@'.$revision, $revision);
?>
The one appended to the URL is the peg revision, and the one in the second paramer is the operative revision.
This seems to cover all the bases.
There is a difference how svn cat works for deleted files. For deleted file commandline `svn cat -r xxx <full_url>` will give error, but 'svn cat <full_url>@xxx` will cat file from the past.
Unfortunately this method will not cat deleted file.
