使用ID项构建链接

Question

I'm developing an app (PHP + CodeIgniter) that has some messages (modal messages) like:

"Invoice #212 generated" or "This invoice is associated with payment #685."

Well, that ID numbers I wanna make a link to redirect user to the respective item (invoice, payment, product, person, whatever...)

So, I thought to develop at server-side, while building messages like:

str="Invoice#212 generated.";
replace(str, "invoice#222", "<a href='invoice/222'>invoice #222</a>")

Of course, using regex or something like that.

Is this the best way? Any suggestion?

Messages are generated inside actions, using global function "set_message" And Messages as "printed" inside header, using function "echo_message"

In PHP you could have something like this (rough generic example):

$string = 'Invoice #212 generated'; // or 'See payment #121'
$string = preg_replace('/(\w+) #(\d+)/', '<a href="/$1/$2">$0</a>', $string);

Pretty flexible if you don't want to change previously generated strings.
