PHP Extension

Change the Filename of an Attachment

Demonstrates the Chilkat Email.SetAttachmentFilename method, which changes the filename of the attachment at a given zero-based index. This example adds an attachment and renames it, printing the filename before and after.

Background: The attachment filename is what a recipient sees and what most clients suggest when saving the file. Renaming it is handy when the original name is unclear, unsafe, or generic — for example giving a machine-generated tmp12345 a meaningful name like invoice.pdf before sending.
