====== PHP RFC: Add suffix-parameter to tempnam ======

===== Introduction =====

Current it is possible to optionally specify a prefix to generated filenames. In some cases however it is needed to create files with a certain suffix (like a file-extension) because other tools rely on for example a graphic-name ending with .png.

There is already a "prefix"-parameter that will be used in front of the automatically generated temporary name. The "suffix" proposed here, if specified, will be added to the end of the resulting temporary name.

===== Proposal =====

Add new, optional parameter $suffix to tempnam().

===== Backward Incompatible Changes =====

The suffix-parameter is optional. Thus it is transparent to any existing PHP-code in use.

Only internal API if affected because of the additional parameter which is added.

===== Proposed PHP Version(s) =====

5.6

===== SAPIs Impacted =====

all

===== Impact to Existing Extensions =====

none
