php File operations

本文实例分析了php文件操作的方法。分享给大家供大家参考,具体如下:

一、删除文件

unlink()

语法: int unlink(string filename);

返回值: 整数

函数种类: 文件存取。如:

unlink("tmp/test.txt");
Copy after login

二、获取文件夹下面的文件名

$dir = "message/"; // 文件夹的名称
if (is_dir($dir)){
  if ($dh = opendir($dir)){
    while (($file = readdir($dh)) !== false){
      echo "文件名: $file <br>";
    }
    closedir($dh);
  }
}

Copy after login

三、读取文件夹下面的图片名

<&#63;php
$handle = opendir('images/'); //当前目录
  while (false !== ($file = readdir($handle))) { //遍历该php文件所在目录
   list($filesname,$kzm)=explode(".",$file);//获取扩展名
    if($kzm=="gif" or $kzm=="jpg" or $kzm=="JPG") { //文件过滤
     if (!is_dir('./'.$file)) { //文件夹过滤
      $array[]=$file;//把符合条件的文件名存入数组
      $i++;//记录图片总张数
      }
     }
  }
 print_r($array);
&#63;>

Copy after login
