The svn class encapsulated by PHP uses the built in svn function to implement the example of exporting related files according to the svn version number

In this paper, the svn class encapsulated by PHP uses the built-in svn function to export related files according to svn version number. Share it for your reference, as follows:

<?php
$revision_array = array(3099, 3339, 2573,3351); /* svn Version number of  */
$svnPeer = new svnPeer();
$filelist = $svnPeer->_get_file_list($revision_array);
if (!empty($filelist))
{
  $lbv_export = $svnPeer->_svn_export_list($filelist, 'trunk889');
  if (true === $lbv_export)
  {
    echo ' Export succeeded ';
  }
  else
  {
    echo ' Export failed ';
  }
}
else
{
  echo ' Failed to get file list ';
}
