php 生成自动创建文件夹并上传文件的示例代码

代码如下:

<?

session_start()

if($_SESSION['Company']=='')

{

//exit()

}

?><?php

//上传图片

$uptypes=array('image/jpg','image/jpeg','image/png','image/pjpeg','image/gif','image/bmp','application/x-shockwave-flash','image/x-png')

$max_file_size=5000000

//上传文件大小限制,

单位BYTE

$addtime=date("Ymd",time())

$testdir="./".$addtime."/"

if(file_exists($testdir)):

else:

mkdir($testdir,0777)

endif

$destination_folder=$addtime."/"

//上传文件路径

$imgpreview=1

//是否生成预览图(1为生成,其他为不生成)

$imgpreviewsize=1/2

//缩略图比例

if

($_SERVER['REQUEST_METHOD']

==

'POST')

{

if

(!is_uploaded_file($_FILES["Pic"][tmp_name]))

//是否存在文件

{

echo

"<font

color='red'>文件不存在！</font>"

exit

}

$file

=

$_FILES["Pic"]

if($max_file_size

<

$file["size"])

//检查文件大小

{

echo

"<font

color='red'>文件太大！</font>"

exit

}

if(!in_array($file["type"],

$uptypes))

//检查文件类型

{

echo

"<font

color='red'>只能上传图像文件或Flash！</font>"

exit

}

if(!file_exists($destination_folder))

mkdir($destination_folder)

$filename=$file["tmp_name"]

超简单，假设当前脚本文件在a/目录中，代码如下：

if (!is_dir('b/')) mkdir('b/') // 如果不存在则创建

// 在检测b/目录中是否存在c.php文件

if (!file_exists('b/c.php')) file_put_contents('b/c.php', 'd') // 如果c.php不存在则创建，当然还可以使用$file = fopen('b/c.php', 'a+')的方式创建然后用fwrite('d', $file)写入d

以上若还有任何问题，欢迎追问~
