Code first letter uppercase help

[mark1million]

I have this code being used on my system and I want to ensure this happens,

User input is, john doe acb1234

Convert to, John Doe ABC1234 So first letter in the names are upper case, airline code is capitals.

I have been looking at, I already have the variable $pilot_id_full outputting correctly.

$pilot_id_full = $fname.' '.$lname.' '.$code;

So i was thinking,

$pilot_id_full = ucfirst ($fname.' '.$lname).' '.$code;

Not tested by the way just is why im after a bit of guidance of the best way to achieve this.

$pilot_id_full = ucfirst($fname).' '.ucfirst($lname).' '.$code;
