Use only if you send a file.

First we try to use MIME_Type, if installed, to detect the content type, else we check if ext/mime_magic is loaded and properly configured.

Returns PEAR_Error if:

• MIME_Type failed to detect a proper content type (HTTP_DOWNLOAD_E_INVALID_CONTENT_TYPE)
• ext/magic.mime is not installed, or not properly configured (HTTP_DOWNLOAD_E_NO_EXT_MMAGIC)
• mime_content_type() couldn't guess content type or returned a content type considered to be bogus by setContentType() (HTTP_DOWNLOAD_E_INVALID_CONTENT_TYPE)

Return value

Returns TRUE on success, PEAR_Error on failure.

Note

This function can not be called statically.
