How to Rename Uploaded Files Before Saving Them to a Directory?

Renaming Uploaded Files Before Saving Them to a Directory

In this context, the move_uploaded_file() function handles the preservation of uploaded files in a designated directory. To assign a random number as the file name, implement the following adjustments:

<br>$temp = explode(".", $_FILES"file");<br>$newfilename = round(microtime(true)) . '.' . end($temp);<br>move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);<br>

The modified code accomplishes the following:

• $temp = explode(".", $_FILES"file"); separates the file extension from the file name.
• $newfilename = round(microtime(true)) . '.' . end($temp); generates a random number based on the current time and appends the original file extension.
• move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename); saves the uploaded file to the designated directory using the newly assigned random file name.
