Question

Let’s say I’m using simpleXML to parse weather data from a remote server, and then the remote server crashes so I can no longer recover its live feeds but I don’t want my users to get an error message either, how would I go about caching and continuing to display the last piece of data I got from the server before it crashed?

Let’s say my xml looks like this:

<weather>
    <temperature c="25" f="77">
</weather>

How would I go about displaying the values “25” and “77” until I’m able to reestablish a connection with the remote server?

Apologies if my question isn’t entirely clear… my knowledge of server-side technologies is very limited.

Answer 1

This isn’t the best way, but here is one way you could do it:

To save the information

$file = 'temp_cache.php';
// Open the file to get existing content
$content = '<?php $c="25"; $f="77"; ?>';
// Write the contents to the file
file_put_contents($file, $content);

To load it

include_once('temp.php');

By including the file, your $c and $f variables will be set unless you overwrite them.
