php后台接受上传图片

配合上个博文的，捣鼓了一个php后台的东西，虽然不怎么懂，但慢慢来，还是可以的。传送门

java太不好学了，玩玩php，满足一下自己。

那个图片压缩的效果很明显，居然压缩了好几倍。

<?php
header('Content-type:text/html; charset="utf-8"');
$base64_image_content=$_POST["file"];
//var_dump($$base64_image_content);
if(preg_match('/^(data:\s*image\/(\w+);base64,)/i',$base64_image_content,$result)){$type=$result[2];$new_file="upload/".date("Ymd",time())."/";if(!file_exists($new_file)){/*权限问题，0777是最好的，其他可能会被禁止*/mkdir($new_file,0777);echo "创建成功";}else{echo "创建失败";}$new_file=$new_file.time().".{$type}";if(file_put_contents($new_file,base64_decode(str_replace($result[1],"",$base64_image_content)))){echo "成功";}else{echo "失败";}}else{echo "不匹配!!";
}
?>

表单提交，传送图片

<?php
header('Content-type:text/html; charset="utf-8"');
$upload_dir = 'uploads/';if(strtolower($_SERVER['REQUEST_METHOD']) != 'post'){exit_status(array('code'=>1,'msg'=>'错误提交方式'));
}if(array_key_exists('file',$_FILES) && $_FILES['file']['error'] == 0 ){$pic = $_FILES['file'];if(move_uploaded_file($pic['tmp_name'], $upload_dir.$pic['name'])){exit_status(array('code'=>0,'msg'=>'上传成功','url'=>$upload_dir.$pic['name']));}}
echo $_FILES['file']['error'];
exit_status(array('code'=>1,'msg'=>'出现了一些错误'));function exit_status($str){echo json_encode($str);exit;
}
?>
