Is it possible to validate them if someone has forgot to choose one of the 3?

Yes but I haven't done PHP for years so can't remember how.
At a guess you would need to loop through each one, set a boolean value if one has been selected and then evaluate that boolean at the end.
There might be a neater way to do it but i'm a .Net man so I couldn't tell you.

just do a javascript function check before you pass to html, makes life easier (and quicker) for the user. also saves having to pass loads of shit back into the form from the phpscript for data already entered

You'd validate them in the same way as you would in any language really. You're effectively doing the same thing, just using specific expressions.
You just want to check there is a value coming from the radio buttons, so you would use something like:
code:
if(!isset(radio_buttons)){
echo "You need to select an option from the radio buttons mate";
}

Can't you just make one of them selected by default?
In the HTML output, something like:
<input type="radio" name="sex" value="male" checked="checked"> Male</input>
