废话少说，直接上代码：
PHP;">
0) {
$filename = $save_path . '/' . uniqid() . '.jpg';
$handle = fopen($filename,'w+');
fwrite($handle,$postdata);
fclose($handle);
if (is_file($filename)) {
echo 'Image data save successed,file:' . $filename;
exit ();
} else {
die ('Image upload error!');
}
} else {
die ('Image data not detected!');
}
PHP;">
0) {
switch ($_FILES ['Filedata'] ['error']) {
case 1 :
$error_log = 'The file is bigger than this PHP installation allows';
break;
case 2 :
$error_log = 'The file is bigger than this form allows';
break;
case 3 :
$error_log = 'Only part of the file was uploaded';
break;
case 4 :
$error_log = 'No file was uploaded';
break;
default :
break;
}
die ('upload error:' . $error_log);
} else {
$img_data = $_FILES['Filedata']['tmp_name'];
$size = getimagesize($img_data);
$file_type = $size['mime'];
if (!in_array($file_type,array('image/jpg','image/jpeg','image/pjpeg','image/png','image/gif'))) {

die ('upload error:' . $error_log);
}
switch ($file_type) {
case 'image/jpg' :
case 'image/jpeg' :
case 'image/pjpeg' :
$extension = 'jpg';
break;
case 'image/png' :

break;

break;
}
}
if (!is_file($img_data)) {
die ('Image upload error!');
}
// 图片保存路径,默认保存在该代码所在目录(可根据实际需求修改保存路径)
$save_path = dirname(FILE);
$uinqid = uniqid();
$filename = $save_path . '/' . $uinqid . '.' . $extension;
$result = move_uploaded_file($img_data,$filename);
