File upload is one of the most commonly used functions when we process form submissions First, I wrote a small demo today, as follows:

Let’s look at the structure first:

html is the page for form submission, and php is for processing the form. file, upload is the location where the uploaded file is placed

html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>文件上传</title>
</head>
<body>
<form action="file_updata.php" method="post" enctype="multipart/form-data">
    <label for="files">文件上传</label>
    <input type="file" id="files" name="file">
    <br/>
    <input type="submit" name="submits" value="提交">
</form>

</body>
</html>

php：

$file = $_FILES["file"];
if ($file["error"] > 0) {
    echo "错误：" . $file["error"];
} else {
    echo "文件名称：" . $file["name"] . "</br>";
    echo "文件类型：" . $file["type"] . "</br>";
    echo "文件大小：" . ($file["size"] / 1024) . "K</br>";
    echo "文件临时存储的位置：" . $file["tmp_name"] . "</br>";


    //保存上传的文件
    if (file_exists("upload" . $file["name"])) {
        echo $file["name"] . "文件已经存在";
    } else {
        //如果目录不存在则将该文件上传

        move_uploaded_file($file[&#39;tmp_name&#39;], "upload/" . $file["name"]);
        echo &#39;文件上传成功!&#39;;


    }
}

I uploaded a .txt file, as follows:

Execution:

You can see that it is very smooth, let’s take a look at the result:

The file uploaded at this time is what we want, but it is garbled. Well, okay, let’s solve it:

First, add Such a piece of code:

header("Content-type: text/html; charset=utf-8");

Then define a variable:

$name = iconv(&#39;utf-8&#39;,&#39;gb2312&#39;,"upload/".$file["name"]);

Okay, let’s look at the entire PHP page:

header("Content-type: text/html; charset=utf-8");
$file = $_FILES["file"];
if($file["error"]>0){
    echo "错误：".$file["error"];
}else{
    $name = iconv(&#39;utf-8&#39;,&#39;gb2312&#39;,"upload/".$file["name"]);
    echo "文件名称：".$file["name"]."
";
    echo "文件类型：".$file["type"]."
";
    echo "文件大小：".($file["size"]/1024)."K
";
    echo "文件临时存储的位置：".$file["tmp_name"]."
";


    //保存上传的文件
    if(file_exists("upload".$file["name"])){
        echo $file["name"]."文件已经存在";
    }else{
        //如果目录不存在则将该文件上传
        if(move_uploaded_file($file['tmp_name'],$name)){
//            move_uploaded_file($file['tmp_name'],"upload/".$file["name"]);
            echo '文件上传成功!';
            echo '图片信息：';
            print_r($file);
        }
    }

Run:

Perfect.
