I'm replying to my post to clarify: I will re-write my PHP apps in other languages when I can now that multi-billion $ competitors have passed me by, but I'm now married to PHP in another way, as PHP is the freshest item on my resume. I've found that skill in this language is shockingly unsaleable compared with things like Java. Check out the help wanteds if you don't believe me. Employers have told me that they look for skills in a more substantive language, like C or Perl, even if the position will be mostly PHP programming because the last is a considerably simpler, derivative language.
If you've been pretty focused on PHP development for a while, your other skills may now be at least a version behind. If you develop a distinct lack of enthusiasm for the language on top of this don't be surprised that this reveals itself at interview. You may then find manning the proverbial hot dog stand looming rather large in your future. The fresh air may do you good but the point remains: think of the children before choosing PHP. :) Somehow that's not as funny on second reading.
Yes, I program alot better in other languages (particularly with a good IDE and clear documentation) but either I'm from Mars or this would be the general experience for the reasons already stated.
