For unique file Name saving

In 5.3 (best for me because use md5_file hashname in Illuminate\Http\UploadedFile):

<pre><code>public function saveFile(Request $request) {
 $file = $request-&gt;file('your_input_name')-&gt;store('your_path','your_disk');
}
</code></pre>

In 5.4 (use not unique Str::random(40) hashname in Illuminate\Http\UploadedFile). I Use this code to ensure unique name:

<pre><code>public function saveFile(Request $request) {
 $md5Name = md5_file($request-&gt;file('your_input_name')-&gt;getRealPath());
 $guessExtension = $request-&gt;file('your_input_name')-&gt;guessExtension();
 $file = $request-&gt;file('your_input_name')-&gt;storeAs('your_path', $md5Name.'.'.$guessExtension ,'your_disk');
}
</code></pre>

You can rename your uploaded file as you want . you can use either move or storeAs method with appropiate param.

<pre><code>$destinationPath = 'uploads';
$file = $request-&gt;file('product_image');
foreach($file as $singleFile){
 $original_name = strtolower(trim($singleFile-&gt;getClientOriginalName()));
 $file_name = time().rand(100,999).$original_name;
 // use one of following 
 // $singleFile-&gt;move($destinationPath,$file_name); public folder
 // $singleFile-&gt;storeAs('product',$file_name); storage folder
 $fileArray[] = $file_name;
}
print_r($fileArray);
</code></pre>

at the top after namespace
use Storage;

<pre><code> Just do something like this ....
</code></pre>

// read files 
 $excel = $request->file('file');

<pre><code>// rename file
$excelName = time().$excel-&gt;getClientOriginalName();

// rename to anything
$excelName = substr($excelName, strpos($excelName, '.c'));
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;
$excel-&gt;move(public_path('equities'),$excelName);
</code></pre>

This guy collect the extension only: 

<pre><code> $excelName = substr($excelName, strpos($excelName, '.c'));
</code></pre>

This guy rename its: 
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;

I am allowing users to upload any kind of file on my page, but there might be a clash in names of files. So, I want to rename the file automatically, so that anytime any file gets uploaded, in the database and in the folder after upload, the name of the file gets changed also when other user downloads the same file, renamed file will get downloaded.
I tried:
<pre><code>if (Input::hasFile('file')){
 echo &quot;Uploaded&lt;/br&gt;&quot;;
 $file = Input::file('file');
 
 $file -&gt;move('uploads');
 $fileName = Input::get('rename_to');
 
 }
</code></pre>
But, the name gets changed to something like:
<blockquote>
php5DEB.php
phpCFEC.php
</blockquote>
What can I do to maintain the file in the same type and format and just change its name?
I also want to know how can I show the recently uploaded file on the page and make other users download it??

我允许用户在我的页面上上传任何类型的文件，但是文件的名称可能会发生冲突。所以，我想要自动重命名文件，以便任何时候任何文件被上传，在数据库中，在上传后在文件夹中，当其他用户下载相同的文件，重命名的文件时，文件的名称也会被更改。我试过：if (Input::hasFile('file')){ echo "Uploaded"; $file = Input::file
