+--TEST--
+Bug #70322 (ZipArchive::close() doesn't indicate errors)
+--DESCRIPTION--
+We want to test whether ZipArchive::close() returns FALSE and raises a warning
+on failure, so we force the failure by adding a file to the archive, which we
+delete before closing.
+--SKIPIF--
+<?php
+if (!extension_loaded('zip')) die('skip requires zip extension');
+?>
+--FILE--
+<?php
+$zipfile = __DIR__ . '/bug70322.zip';
+$textfile = __DIR__ . '/bug70322.txt';
+touch($textfile);
+$zip = new ZipArchive();
+$zip->open($zipfile, ZipArchive::CREATE);
+$zip->addFile($textfile);
+unlink($textfile);
+var_dump($zip->close());
+?>
+--CLEAN--
+<?php
+// we don't expect the archive to be created, but clean up just in case...
+@unlink(__DIR__ . '/bug70322.zip');
+?>
+--EXPECTF--
+Warning: ZipArchive::close(): Read error: No such file or directory in %s%ebug70322.php on line %d
