<simpara><filename>compress.zlib://</filename> e <filename>compress.bzip2://</filename></simpara>
<simpara>
<filename>zlib:</filename> funziona come <function>gzopen</function>, tranne che il
flusso può essere utilizzato con <function>fread</function> e le altre
funzioni del filesystem. Questo è deprecato a causa di
ambiguità con i nomi di file contenenti il carattere ':'; utilizzare
<filename>compress.zlib://</filename> al suo posto.
</simpara>
<simpara>
<filename>compress.zlib://</filename> e
<filename>compress.bzip2://</filename> sono equivalenti a
<function>gzopen</function> e <function>bzopen</function>
rispettivamente, e funzionano anche su sistemi che non supportano
fopencookie.
</simpara>
<simpara>
L'<link linkend="book.zip">estensione ZIP</link> registra il wrapper <filename>zip:</filename>. A partire da
PHP 7.2.0 e libzip 1.2.0+, è stato aggiunto il supporto per le password degli archivi crittografati,
permettendo di fornire le password tramite i contesti di flusso. Le password possono essere impostate utilizzando
l'opzione di contesto di flusso <literal>'password'</literal>.
