但我担心重复,所以我打算将图像上传为随机数

好吧,这里是我的代码,你可以理解,无论如何我想通过它

<label for="file">Profile Pic:</label> <input type="file" name="ProfilePic" id="ProfilePic" /><br />

<input type="submit" name="submit" value="Submit" />

$ProfilePicName = $_FILES["ProfilePic"]["name"];
$ProfilePicType = $_FILES["ProfilePic"]["type"];
$ProfilePicSize = $_FILES["ProfilePic"]["size"];
$ProfilePicTemp = $_FILES["ProfilePic"]["tmp_name"];
$ProfilePicError = $_FILES["ProfilePic"]["error"];

$RandomAccountNumber = mt_rand(1,99999);  
echo $RandomAccountNumber; 
move_uploaded_file($ProfilePicTemp,"Content/".$RandomAccountNumber.$ProfilePicType);

然后基本上所有这一切后,我试着把它随机数放在我的数据库中

有人给了我一个新的片段,看起来它会做我想要的但现在文件不是一直到我的目录

$RandomAccountNumber = uniqid();
echo $RandomAccountNumber;

move_uploaded_file($ProfilePicName,"Content/".$RandomAccountNumber);
