$tmp_filename = $_FILES['content']['tmp_name']; 
$upload_status = move_uploaded_file($tmp_filename, $filepath);
?>           

$_FILES['content']['tmp_name'] - $_FILES array is where PHP stores all the information about files.
There are two elements of this array - content and tmp_name

content - document content that is uploaded to Zoho editors while doing a HTTP multi-part form POST.
tmp_name - tmp_name contains the path to the temporary file that resides on the Zoho document server. 

move_uploaded_file - Thisfunction moves the temporary file from 
Zoho's document server to the document repository folder path that you provide 
along with the file name and file extension.

Note: Example of doc repository folder path - "/apache/htdocs/zohosave/samplefile.docx" 
or "C:\Zylker\Documents\samplefile.docx"
