REQUIREMENTS
|
|
|
|
MapieRSS requires a recent PHP 4+ (developed with 4.2.0)
|
|
with xml (expat) support.
|
|
|
|
Optionally:
|
|
* PHP5 with libxml2 support.
|
|
* cURL for SSL support
|
|
* iconv (preferred) or mb_string for expanded character set support
|
|
|
|
QUICK START
|
|
|
|
Magpie consists of 4 files (rss_fetch.inc, rss_parser.inc, rss_cache.inc,
|
|
and rss_utils.inc), and the directory extlib (which contains a modified
|
|
version of the Snoopy HTTP client)
|
|
|
|
Copy these 5 resources to a directory named 'magpierss' in the same
|
|
directory as your PHP script.
|
|
|
|
At the top of your script add the following line:
|
|
|
|
require_once('magpierss/rss_fetch.inc');
|
|
|
|
Now you can use the fetch_rss() method:
|
|
|
|
$rss = fetch_rss($url);
|
|
|
|
Done. That's it. See README for more details on using MagpieRSS.
|
|
|
|
NEXT STEPS
|
|
|
|
Important: you'll probably want to get the cache directory working in
|
|
order to speed up your application, and not abuse the webserver you're
|
|
downloading the RSS from.
|
|
|
|
Optionally you can install MagpieRSS in your PHP include path in order to
|
|
make it available server wide.
|
|
|
|
Lastly you might want to look through the constants in rss_fetch.inc see if
|
|
there is anything you want to override (the defaults are pretty good)
|
|
|

SETTING UP CACHING
|
|
|
|
Magpie has built-in transparent caching. With caching Magpie will only
|
|
fetch and parse RSS feeds when there is new content. Without this feature
|
|
your pages will be slow, and the sites serving the RSS feed will be annoyed
|
|
with you.
|
|
|
|
** Simple and Automatic **
|
|
|
|
By default Magpie will try to create a cache directory named 'cache' in the
|
|
same directory as your PHP script.
|
|
|
|
** Creating a Local Cache Directory **
|
|
|
|
Often this will fail, because your webserver doesn't have sufficient
|
|
permissions to create the directory.
|
|
|
|
Exact instructions for how to do this will vary from install to install and
|
|
platform to platform. The steps are:
|
|
|
|
1. Make a directory named 'cache'
|
|
2. Give the web server write access to that directory.
|
|
|
|
An example of how to do this on Debian would be:
|
|
|
|
1. mkdir /path/to/script/cache
|
|
2. chgrp www-data /path/to/script/cache
|
|
3. chmod 775 /path/to/script/cache
|
|
|
|
On other Unixes you'll need to change 'www-data' to what ever user Apache
|
|
runs as. (on MacOS X the user would be 'www')
|
|
|
|
** Cache in /tmp **
|
|
|
|
Sometimes you won't be able to create a local cache directory. Some reasons
|
|
might be:
|
|
|
|
1. No shell account
|
|
2. Insufficient permissions to change ownership of a directory
|
|
3. Webserver runs as 'nobody'
|
|
|
|
In these situations using a cache directory in /tmp can often be a good
|
|
option.
|
|
|
|
The drawback is /tmp is public, so anyone on the box can read the cache
|
|
files. Usually RSS feeds are public information, so you'll have to decide
|
|
how much of an issue that is.
|
|
|
|
To use /tmp as your cache directory you need to add the following line to
|
|
your script:
|
|
|
|
define('MAGPIE_CACHE_DIR', '/tmp/magpie_cache');
|
|
|
|
** Global Cache **
|
|
|
|
If you have several applications using Magpie, you can create a single
|
|
shared cache directory, either using the /tmp cache, or somewhere else on
|
|
the system.
|
|
|
|
The upside is that you'll distribute fetching and parsing feeds across
|
|
several applications.
|
|
|
|
INSTALLING MAGPIE SERVER WIDE
|
|
|
|
Rather then following the Quickstart instructions which requires you to have
|
|
a copy of Magpie per application, alternately you can place it in some
|
|
shared location.
|
|
|
|
** Adding Magpie to Your Include Path **
|
|
|
|
Copy the 5 resources (rss_fetch.inc, rss_parser.inc, rss_cache.inc,
|
|
rss_utils.inc, and extlib) to a directory named 'magpierss' in your include
|
|
path. Now any PHP file on your system can use Magpie with:
|
|
|
|
require_once('magpierss/rss_fetch.inc');
|
|
|
|
Different installs have different include paths, and you'll have to figure
|
|
out what your include_path is.
|
|
|
|
From shell you can try:
|
|
|
|
php -i | grep 'include_path'
|
|
|
|
Alternatley you can create a phpinfo.php file with contains:
|
|
|
|
<?php phpinfo(); ?>
|
|
|
|
Debian's default is:
|
|
|
|
/usr/share/php
|
|
|
|
(though more idealogically pure location would be /usr/local/share/php)
|
|
|
|
Apple's default include path is:
|
|
|
|
/usr/lib/php
|
|
|
|
While the Entropy PHP build seems to use:
|
|
|
|
/usr/local/php/lib/php |
