------解决方案--------------------
能一样吗?
echo "Name: " . $file_name=zip_entry_name($zip_entry) . "
"; //返回 ZIP 文件中的一个项目的名称
中 $file_name=zip_entry_name($zip_entry) . "
" 这不是后面还有
吗?
在 echo 中赋值的话,应写作
echo "Name: " .( $file_name=zip_entry_name($zip_entry) ). "
";
或
echo "Name: " , $file_name=zip_entry_name($zip_entry) , "
";
