On the heels of my last php script, I had to modify this slightly to compare our version of a website (in this case a joomla website) against a vanilla version of the joomla install.

It was fairly straight forward…

On a local webserver I created a folder called compare. In there I created two directories… one calle ‘branch’ and another called ‘ vanilla’. Also in this directory is where I placed the phpscript below.

In the vanilla folder i placed the original joomla code and in the branch folder I placed a copy of the modified website. Then I ran the script:

  function compareDirectories( $path = ‘.’, $level = 0 ){
     $ignore = array( ‘cgi-bin’, ‘.’, ‘..’ );
     $dh = ( $path );
     while( false !== ( $file = readdir( $dh ) ) ){ // Loop through the directory 
 
     nbsp; if( !in_array( $file, $ignore ) ){    
 
         if( is_dir( “$path/$file” ) ){
         nbsp; // Its a directory, so we need to keep reading down…
         nbsp; compareDirectories( “$path/$file”, ($level+1),$time ); 
 
         } else {
         nbsp; compareFiles(”$path/$file”);
         }//elseif 
 
     nbsp; }//if in array  
  
     }//while
     closedir( $dh ); 
   }
 
  function compareFiles( $path = ‘.’ ){
     $vanilla_path = $path;
     $branch_path = str_replace(”vanilla”,”branch”,$path); 
    if(file_exists($branch_path)){
     if( strcmp(file_get_contents($vanilla_path),file_get_contents($branch_path)) ){
         echo “$vanilla_path $branch_path -DIFFERENCE DETECTED
”;     
  
     nbsp; }
        
     }
     return true;
   } 
  compareFiles( “./vanilla”,0);
   
 ?> 

Basically it produces a list of files that differ from the vanilla version…
