使用 php 上传到服务器后图像大小显示为零字节

Image size showing Zero byte after uploading on server using php

我正在使用 croppie 插件裁剪图像,效果很好。图像存储在我的文件夹中,图像大小显示为零 bytes.It 在本地主机上运行良好,但在服务器上运行不正常。你愿意帮我吗?

<form action="process.php" id="form" method="post">
<div id="upload-demo"></div>
<input type="hidden" id="imagebase64" name="imagebase64">
<input type="submit" name="submit" value="save" class="upload-result">
</form>
    if(isset($_POST['submit'])){
            $data = $_POST['imagebase64'];
            list($type, $data) = explode(';', $data);
            list(, $data)      = explode(',', $data);
            $data = base64_decode($data);
            $imageName = time().'.png';
            file_put_contents('images/profile/'.$imageName, $data);
           // echo $imageName;
        }

这是工作文件。这可能对你有帮助。

<?php
if(isset($_POST['imagebase64'])){
    $data = $_POST['imagebase64'];

    list($type, $data) = explode(';', $data);
    list(, $data)      = explode(',', $data);
    $data = base64_decode($data);

    file_put_contents('image64.png', $data);
}
?>
