I'm putting together a kind of ColdFusion Tips website and I'm currently working on an article about Duck Typing. I tend to "type" most of my variables because it seems safer to me, and also perhaps because I come from a strong C/Database background. I just wanted to know how you guys felt about it.

considering most programming languages require types, it's lazy not too.

I voted "sometimes" because there are instances where I may be using both a form AND url variable. I know, it's a bad practice, but sometimes it's just easier.

I never scoped by variables in PHP either though sad.gif

Every language should include types... unless you are defining a general type for the use of inheritence and instances.

ColdFusion has types, but you're not required to specify them. You can easily do something like this:

CODE


<cfset myTest = 4>
<cfset myTest = myTest * myTest>
<cfoutput>My Answer : #Replace(myTest,6,1)#</cfoutput>

My Answer : 11

I never even thought of how this applied to scoping, I'll be adding something about that to my article. Thanks!!

no, i realize they are not required, php does not require them either, they are implied by the data placed into them.

My point was unless you have reason to leave it out (besides laziness) it is good practise to include them. It is much easier to remove them afterwards, than to find the places to put them in, i've found.
