There's nothing wrong with PHP as a language, but I've never seen people offering to write python for fifteen dollars an hour.
And it's not like saying that doctors aren't a profession because there are homeopaths, because homeopaths aren't doctors. The segment of our industry that is more EE than CS is highly professional, somewhat organized, and relatively mature for an industry only fifty years old, but they are a small, nonvocal segment of our industry and they tend to distance themselves from the people who call themselves "developers."
Don't burst a vein arguing over the definition of a profession.
The litmus test is whether or not an occupation has a policing organisation who dictates who is allowed to practice it. Lawyers, doctors, civil engineers are professions. Homeopathers, developers and ditch diggers are not.
