输入类型=文件是否出现在$ _POST中？

Question

I have this within a form and I was thinking that as its an input name I should be able to detect it with $_POST[] but I cant see it. Which would explain when I do isset on it nothing happens. Am I not understanding it correctly?

<input type="file" id="files" name="files"  class="hidden" multiple="" >
<label for="files">Select file</label>

You can access posted file data in $_FILES

You can get file name, file type, tmp_name, error, size in $_FILES

Simple exmaple is:

Html:

<form action="upload_manager.php" method="post" enctype="multipart/form-data">
    <h2>Upload File</h2>
    <label for="fileSelect">Filename:</label>
    <input type="file" name="photo" id="fileSelect"><br>
    <input type="submit" name="submit" value="Upload">
</form>

In php:

<?php
if($_FILES["photo"]["error"] > 0){
    echo "Error: " . $_FILES["photo"]["error"] . "<br>";
} else{
    echo "File Name: " . $_FILES["photo"]["name"] . "<br>";
    echo "File Type: " . $_FILES["photo"]["type"] . "<br>";
    echo "File Size: " . ($_FILES["photo"]["size"] / 1024) . " KB<br>";
    echo "Stored in: " . $_FILES["photo"]["tmp_name"];
}
?>
