PHP traversal folder and file classes and processing classes

FindFile.class.php

Used to traverse a directory file

<?php/** Traverse folder and File class * date:2013-03-21 * Author:fdipzone * ver:1.0/class findfile{    Public $files = Array ();        Store the traversed file protected $maxdepth;  Search depth, 0 means no Limit/* Traverse file and folder * @param String $spath folder path * @param int $maxdepth Search depth, default search all */Public function process ($spath, $maxdepth =0) {if (Isset ($maxdepth) && is_numeric  
        ($maxdepth) && $maxdepth >0) {$this->maxdepth = $maxdepth;  
        }else{$this->maxdepth = 0;  
        } $this->files = Array (); $this->traversing ($spath); 
    Traverse}/* Traverse file and folder * @param String $spath folder path * @param int $depth current folder depth * * Private function traversing ($spath, $depth =1) {if ($handle = Opendir ($spath)) {while ($f Ile=readdir ($handle))!==false {if ($file!= '. ' && $file!= ' ... '){$curfile = $spath. '  
      
                    /'. $file;  
                            if (Is_dir ($curfile)) {//dir if ($this->maxdepth==0 | | $depth < $this->maxdepth) {//Judge depth  
                        $this->traversing ($curfile, $depth + 1);  
                    }}else{//File $this->handle ($curfile);  
        }} closedir ($handle);  
        /** Processing File Method * @param String $file file path */protected function handle ($file) {  
    Array_push ($this->files, $file); }}?>

UnsetBom.class.php is used to clear the BOM for the Utf8+bom file, that is, the first three bytes 0xEF 0xBB 0xBF, inheriting the FindFile class

<?php/** traverse All files, clear Utf8+bom 0xEF 0xBB 0xBF * date:2013-03-21 * author:fdipzone * ver:1.0 * \ Class  
    Unsetbom extends findfile{private $filetype = Array ();//file type/initialization to be processed  
        The Public function __construct ($filetype =array ()) {if ($filetype) {$this->filetype = $filetype; /** Rewrite FindFile handle method * @param String $file File path * * Protected fun  
            Ction handle ($file) {if ($this->check_ext ($file) && $this->check_utf8bom ($file)) {//Utf8+bom        $this->clear_utf8bom ($file);    Clear Array_push ($this->files, $file);  Save log}}/** check if the file is Utf8+bom * @param String $file file path * @return  
        Boolean/Private Function Check_utf8bom ($file) {$content = file_get_contents ($file); Return Ord (substr ($content, 0,1)) ===0xef &Amp;& Ord (substr ($content, 1,1)) ===0xbb && Ord (substr ($content, 2,1)) ===0XBF;  
        /** Clear Utf8+bom * @param String $file File path * * Private function Clear_utf8bom ($file) {  
        $content = file_get_contents ($file); File_put_contents ($file, substr ($content, 3), true);
    Remove the first three bytes}/** check File type * @param String $file File path * @return Boolean * *  
        Private Function Check_ext ($file) {$file _ext = Strtolower (Array_pop (Explode ('. ', basename ($file)));  
        if (In_array ($file _ext, $this->filetype)) {return true;  
        }else{return false; }}}?>

Demo unset UTF8 BOM

<?php  
require (' FindFile.class.php ');  
Require (' UnsetBom.class.php ');  
      
$folder = DirName (__file__);  
      
$obj = new Unsetbom (Array (' PHP ', ' css ', ' JS ')); File type  
$obj->process ($folder);  
      
Print_r ($obj->files);
