PHP traverses folders, file classes and processing classes
FindFile.class.php
Used to traverse directory files
<?php /** 遍历文件夹及文件类 * Date: 2013-03-21 * Author: fdipzone * Ver: 1.0 */ class FindFile{ public $files = array(); // 存储遍历的文件 protected $maxdepth; // 搜寻深度,0表示没有限制 /* 遍历文件及文件夹 * @param String $spath 文件夹路径 * @param int $maxdepth 搜寻深度,默认搜寻全部 */ public function process($spath, $maxdepth=0){ if(isset($maxdepth) && is_numeric($maxdepth) && $maxdepth>0){ $this->maxdepth = $maxdepth; }else{ $this->maxdepth = 0; } $this->files = array(); $this->traversing($spath); // 遍历 } /* 遍历文件及文件夹 * @param String $spath 文件夹路径 * @param int $depth 当前文件夹深度 */ private function traversing($spath, $depth=1){ if($handle = opendir($spath)){ while(($file=readdir($handle))!==false){ if($file!='.' && $file!='..'){ $curfile = $spath.'/'.$file; if(is_dir($curfile)){ // dir if($this->maxdepth==0 || $depth<$this->maxdepth){ // 判断深度 $this->traversing($curfile, $depth+1); } }else{ // file $this->handle($curfile); } } } closedir($handle); } } /** 处理文件方法 * @param String $file 文件路径 */ protected function handle($file){ array_push($this->files, $file); } } ?>
UnsetBom.class.php Used to clear the bom of utf8+bom files, that is, the first three bytes 0xEF 0xBB 0xBF, inherit the FindFile class
<?php /** 遍历所有文件,清除utf8+bom 0xEF 0xBB 0xBF * Date: 2013-03-21 * Author: fdipzone * Ver: 1.0 */ class UnsetBom extends FindFile{ private $filetype = array(); // 需要处理的文件类型 // 初始化 public function __construct($filetype=array()){ if($filetype){ $this->filetype = $filetype; } } /** 重写FindFile handle方法 * @param String $file 文件路径 */ protected function handle($file){ if($this->check_ext($file) && $this->check_utf8bom($file)){ // utf8+bom $this->clear_utf8bom($file); // clear array_push($this->files, $file); // save log } } /** 检查文件是否utf8+bom * @param String $file 文件路径 * @return boolean */ private function check_utf8bom($file){ $content = file_get_contents($file); return ord(substr($content,0,1))===0xEF && ord(substr($content,1,1))===0xBB && ord(substr($content,2,1))===0xBF; } /** 清除utf8+bom * @param String $file 文件路径 */ private function clear_utf8bom($file){ $content = file_get_contents($file); file_put_contents($file, substr($content,3), true); // 去掉头三个字节 } /** 检查文件类型 * @param String $file 文件路径 * @return boolean */ private function check_ext($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')); // 文件类型 $obj->process($folder); print_r($obj->files); ?>
