The function <code class="Fn" title="Fn">zip_file_add</code>() adds a file to a
zip archive, while <code class="Fn" title="Fn">zip_file_replace</code>()
replaces an existing file in a zip archive. The argument
<var class="Ar" title="Ar">archive</var> specifies the zip archive to which
the file should be added. <var class="Ar" title="Ar">name</var> is the file's
name in the zip archive (for
<code class="Fn" title="Fn">zip_file_add</code>()), while
<var class="Ar" title="Ar">index</var> specifies which file should be replaced
(for <code class="Fn" title="Fn">zip_file_replace</code>()). The
<var class="Ar" title="Ar">flags</var> argument can be any combination of
<code class="Dv" title="Dv">ZIP_FL_OVERWRITE</code> with one of
<code class="Dv" title="Dv">ZIP_FL_ENC_*</code>:
