Ben Ramsey has posted a (quick) new items over on his blog that looks at solving two problems he was having with his blog - the now non-functional Flickr feed and a sorting problem with array_multisort.
I recently upgraded a few things around here (in particular, an upgrade to PHP 5.2), and I noticed two issues that occurred after the upgrade. [...] I easily solved both of these issues.
The correction to the Flickr feed involved changing the namespace information for his request (adding a trailing slash) because the SimpleXML functionality got a bit more particular about the format.
The problem with array_multisort involved adding in a parameter that was implied in previous PHP versions, SORT_STRING, to get his code correctly working.
