如何在php中上传/移动大于2Mb的视频[重复]

Question

我正在创建一个提交视频文件的表单；在 php 代码的同一文件中，我将详细信息保存到 sql；问题是如果我上传超过 2Mb 的文件，那么它不会保存到数据库中。

在 php.ini 中，我将 upload_max_filesize 更改为 50M，post_max_size 更改为 100M，file_upload 处于打开状态，同时 memory_limit 设置为 -1；但在我的 phpinfo() 文件中，即使重新启动 apache 服务器后，upload_max_filesize 仍显示 2M，post_max_size 仍显示 8M。我该怎么办？

我不知道直接的解决方案，但你可以尝试这个：

我得到了这个函数来检查base64的文件大小

function checkBase64Size($base64, $maxSizeMB = 1) {

    $decodedBase64 = base64_decode($base64);
    $sizeBytes = strlen($decodedBase64);

    // Convert the max to bytes
    $maxSizeBytes = $maxSizeMB * 1024 * 1024;

    // controls if smaler or equal to cap
    return ($sizeBytes <= $maxSizeBytes);
}

首先你必须将它编码为base64，然后调用该函数来检查它是否大于x。

$base64Encoded = base64_encode($originalString);
//check the size
checkBase64Size($base64Encoded, 2)
