In PHP programming, file uploading can be said to be too common. Let me share a simple code for uploading files in PHP, suitable for beginners.

1. File upload interface up_file.html

<HTML>
    <HEAD>
    <TITLE>文件上传界面</TITLE>
    </HEAD>
    <BODY>
    <table>
    <tr align="center">
    <td><form ENCTYPE="multipart/form-data" NAME="SubmitForm" ACTION="upload.php" METHOD="POST">
    <input type="hidden" name="MAX_FILE_SIZE" value="1000000"><input type="hidden" name="UploadAction" value="1">
    </td></tr>
    <tr align="center">
    <td><input NAME="UploadFile" TYPE="file" SIZE="30"></td>
    </tr>
    <tr align="center">
    <td><input NAME="submit" VALUE="提交" TYPE="submit"></td>
    <td><input NAME="reset" VALUE="重置" TYPE="reset"></td>
    </tr>
    </form>
    </table>
    </center>
    </BODY>
    </HTML>

2. File upload code upload.php

<HTML>
    <HEAD>
    <TITLE>文件上传代码</TITLE>
    </HEAD>
    <BODY>
    <?
    /**
     @文件上传代码 保存上传的文件
     @site http://www.jbxue.com
   */
    $TimeLimit=60; /*设置超时限制时间 缺省时间为30秒 设置为0时为不限时 */
    set_time_limit($TimeLimit);
    If(($UploadFile !="none" ))
    {  
        $UploadPath=AddSlashes(dirname($PATH_TRANSLATED))."\my_files\"; //上载文件存放路径
        $FileName=$UploadPath.$UploadFile_name; //上载文件名
        if($UploadFile_size < 1024) //上载文件大小
        {
      $FileSize=(string)$UploadFile_size." 字节"; 
     }
         elseif ($UploadFile_size <(1024 * 1024))
         {
      $FileSize=number_format((double)($UploadFile_size/1024), 1) . " KB";
         }
      else{
      $FileSize=number_format((double)($UploadFile_size / (1024 * 1024)), 1) . " MB";
         }
       
        if(!file_exists($FileName))
        {
             if(copy($UploadFile,$FileName))
             {  echo "文件 $UploadFile_name ($FileSize)上载成功！"; }
             else
             { echo "文件 $UploadFile_name上载失败！"; }
             unlink($UploadFile);
        }
        else
        { echo "文件 $UploadFile_name已经存在！"; }
    }
    else
    { echo "你没有选择任何文件上载！"; }
    set_time_limit(30); //恢复缺省超时设置
    ?>
    <BR><A HREF = "upload.php">返回</A>
    </BODY>
    </HTML>
