This module allows you to read the meta information stored in the headers of a » RedHat Package Manager (» RPM) file.
The RPMReader extension requires PHP 5.
This » PECL extension is not bundled with PHP.
Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » http://pecl.php.net/package/rpmreader.
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.
The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
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.
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.
Example#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);
?>
