Proposed updates

Hi,

I like the class. Exactly what I need for my release management system. I've modified the non-mysql sections to suit my needs. The mySQL section I've removed from mine as I have my own wrappers.

For the mySQL environment, I'd suggest moving to PDO. Doing something like this (pseudocode):
1. With PHP 5.3+, open connection with
$p = new PDO($dsn, $u, $p, array(PDO::MYSQL_ATTR_FOUND_ROWS => true));. The reason for this is that if you run an update to mysql and the record hasn't changed, the rowCount() will return 0. You don't want this, you want it to tell you 1 if the record exists and 0 if the record does not exist.
2. Do an update of the record (file). Check how many records are effected with rowCount().
3. If Step 2 returns 1, then you know the record exists and it will have been updated already, so there is no need to do any insert. If it returns 0, then you must insert the record.

This will make your code smaller and will lower your overhead (I believe) from first checking if the record exists and then inserting it or updating it. With this method, you'll execute a minimum of 1 SQL query and a maximum of 2, instead of a constant 2 with your current method.

I've also remove most other methods and incorporated them all into a single method getListFiles().

The modified code (with DB section removed, sorry) is:
<?php
/*

class fileScanner {
public $path = array();
public $exceptions = array();
public $tz = "GMT";
public $all_files = array();
public $failed = array();

function __construct($paths=NULL, $exceptions=NULL){
date_default_timezone_set($this->tz);
if(!is_null($paths)) $this->path = $paths;
if(!is_null($exceptions)) $this->path = $exceptions;
}

function scan() {
foreach ($this->path as $p) {
$this->getListFiles($p);
}
}

function getListFiles($dir){
if(is_readable($dir)){
$fp = opendir($dir);
while($cv_file = readdir($fp)) {
$fFullPath = $dir."/".$cv_file;
if(!in_array($fFullPath, $this->exceptions)){
if(is_file($fFullPath)) {
if(is_readable($fFullPath)){
$this->all_files[] = array(
"NAME" => $fFullPath,
"HASH" => md5(file_get_contents($fFullPath)),
"TIME" => filemtime($fFullPath),
"SIZE" => filesize($fFullPath),
);
}else{
$this->failed[] = $fFullPath;
}
}elseif($cv_file!="." && $cv_file!=".." && is_dir($fFullPath)){
$this->getListFiles($fFullPath);
}
}
}
closedir($fp);
}else{
$this->failed[] = $dir;
}
}
}

$scanner = new fileScanner();
$scanner->path = array("/home/genie");
$scanner->exceptions = array(
"/home/genie/domains" ,
"/home/genie/docs" ,
"/home/genie/vendor" ,
"/home/genie/xx__OTHER" ,
"/home/genie/xcache" ,
"/home/genie/logs" ,
"/home/genie/new" ,
"/home/genie/backupsystem"
);
$scanner->scan();
