I think it means you need to put a delimiter around your regex...
Typically you would use slashes (preg_match("/regex/")) but the character

Consider this method:
function xyz() {

A few assumptions:
- Resultant data large enough to warrant discussion of efficiency
- I always want to store the unserialized data into the object
- The return value is only needed sometimes

are really no specific rules.
On that note, something to keep in mind is that GET variables (being part
of the URL) are written to server logs. Depending on the data being
passed, this could be a security issue (especially in a shared hosting
environment where untrusted users may have access to the lo
ost would suggest against in PHP, anyway).
There IS something to OOP! Unfortunately, it's difficult to learn through
examples of car stereo panels or different types of fruit or trees
(though they do make perfect sense in hindsight).

it's a
myth to think simply avoiding (delving into) OOP because "I've heard that
it's slow in PHP" automatically means you're being more efficient. It's
not the prime language for OOP but I find that when it all balances out,
for web apps in PHP, OO offers an attractive
t loop over it as you like, to do your output.
If you're reading an XML file, you might look into PEAR, which has
packages for parsing and building data structures of XML data.
