# CXXXVIII. RPM Header Reading 函数

# 简介

This module allows you to read the meta information stored in the headers of a RedHat Package Manager (RPM) file.

# 需求

The RPMReader extension requires PHP 5.

# 安装

本 PECL 扩展未绑定于 PHP 中。

安装此 PECL 扩展库的信息可在手册中标题为 PECL 扩展库安装的一章中找到。 更多信息如新版本，下载，源文件，维护者信息以及更新日志等可以在这里找到： http://pecl.php.net/package/rpmreader.

# 资源类型

There is one resource type used by the RPMReader module. The resource is a file pointer which identifies the RPM file with which to work.

# 预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

The following list of constants are used to obtain information using the rpm_get_tag() function. These constants represent the tag number to be retrieved from the RPM file's header section. Descriptions are given below as to what data the tag number constants reference.

`RPMREADER_MINIMUM` (integer)

  The minimum valid value of any RPM tag number.

`RPMREADER_NAME` (integer)

  The name of the RPM package.

`RPMREADER_VERSION` (integer)

  The version of the RPM package.

  The release of the RPM package.

`RPMREADER_EPOCH` (integer)

`RPMREADER_SERIAL` (integer)

`RPMREADER_SUMMARY` (integer)

  The summary text of the RPM package.

`RPMREADER_DESCRIPTION` (integer)

  The full description text of the RPM package.

`RPMREADER_BUILDTIME` (integer)

  The date and time when the RPM package was built.

`RPMREADER_BUILDHOST` (integer)

  The name of the host on which the RPM package was built.

`RPMREADER_INSTALLTIME` (integer)

  The list of files in an RPM package (deprecated format). The correct way is now to use a combination of 3 tags (RPMREADER_BASENAMES, RPMREADER_DIRINDEXES, RPMREADER_DIRNAMES) in what RPM now calls "CompressedFileNames". This tag is still used in older RPM files that did not use the "CompressedFileNames" method and is maintained for backward compatibility.

`RPMREADER_BASENAMES` (integer)

# 范例

This example will open an RPM file and read the name, version, and release from the RPM file, echo the results, and close the RPM file.

例 1. Basic RPMReader Example

`<?php $filename = "/path/to/file.rpm"; // open file $rpmr = rpm_open($filename); // get "Name" tag $name = rpm_get_tag($rpmr, RPMREADER_NAME); // get "Version" tag $ver = rpm_get_tag($rpmr, RPMREADER_VERSION); // get "Release" tag $rel = rpm_get_tag($rpmr, RPMREADER_RELEASE); echo "$name-$ver-$rel<br>\n"; // close file rpm_close($rpmr); ?>`
