> Sadly no amount of frameworks or templating engines can stop a bad programmer from writing bad code,

It's not a matter of whether the code is bad or not, but how bad.

The entire point of frameworks is to add guard rails to help you stay disciplined and avoid cutting corners on separation of concerns.

Using PHP as a template language tempts developers to violate SOC every day.

If you need guard rails to keep you from performing database manipulations in your views you have other problems to worry about. And if anything people are cutting corners on SOC in the M and C part of MVC, not the V part.

Also I don't see how using a loop or conditional in PHP is any different from using one in a templating engine, aside from the overhead of the engine and added annoyance of debugging another language in your project.

Those problems are called "junior developers", and I think we'd all like to avoid them, but that's not very sustainable.

Perhaps we can fix the education problem, but given that folks just do a boot camp and head into the market, prospects aren't looking good.

The problem is convention, or lack thereof. Without convention, who's to say where that database call should live? Frameworks, which tend to use templating languages for this reason, tend to make that convention clear to all teammates.

I want to mention that this doesn't mean you can't use PHP as the programming language for your templates as long as the conventions are clear, but PHP is poorly suited to being a template language for reasons I've posted elsewhere in this thread.

Its a one off... Its just an internal tool... This is a prototype... It's a hot fix...

I know better, I have done it. It is only with dumb luck that they didn't end up as products. Some people dont know that they should not or that it isnt a place they should try to "get away" with it. These things grow and then turn into products and someone has to clean them up.

Source: I made a lot of money turning PHP "projects" into "software".

One of these things is Turing complete. The other is not.

Templating languages have their own laments: see yaml configs used to create "workflows", "environments" and "servers" via templating.
