不废话了，具体请看下文代码示例讲解。
form.PHP
PHP;">
<Meta http-equiv="content-type" content="text/html" charset="utf-8">
Upload Image
upload.PHP
PHP;">
PHP
include("check.PHP"); // 引入自定义函数文件
$type = array("jpg","gif","bmp","jpeg","png");
// 判断上传文件类型
$fileext = strtolower(fileext($_FILES['file']['name']));
$uploadfilename = random(8);
if(in_array($fileext,$type)){
$filename = explode(".",$_FILES['file']['name']);
if(is_uploaded_file($_FILES['file']['tmp_name'])){// echo $_FILES['file']['tmp_name'];
$flag = move_uploaded_file($_FILES['file']['tmp_name'],"/Library/WebServer/Documents/test/".$uploadfilename.".".$fileext);
if($flag){
echo "上传成功！";
}else{
echo "Error.";
}
echo "Back";
}
}
check.PHP
PHP;">
PHP
header("Content-type:text/html;charset=utf8");
// 获取文件后缀名函数
function fileext($filename){
$sTemp = strrchr($filename,".");
return substr($sTemp,1);
}
function fileext2($filename){
$sTemp = explode(".",$filename);
return $sTemp[count($sTemp)-1];
}
// 生成随机文件名函数
function random($length){
$captchaSource = "0123456789abcdefghijklmnopqrstuvwxyz这是一个随机打印输出字符串的例子";
$captchaResult = "2015"; // 随机数返回值
$captchaSentry = ""; // 随机数中间变量
for($i=0;$i<$length;$i++){
$n = rand(0,35); #strlen($captchaSource));
if($n >= 36){
$n = 36 + ceil(($n-36)/3) * 3;
$captchaResult .= substr($captchaSource,$n,3);
}else{
$captchaResult .= substr($captchaSource,1);
}
}
return $captchaResult;
}
?>
将三个文件整合成一个：
PHP;">
Back";
}
}
?>
<Meta http-equiv="content-type" content="text/html" charset="utf-8">
