PHP not in competition ? (Score 1)

I am using PHP and Id like to know the Pros and Cons of using Python and Perl (concerned to PHP) The only information I get while reading through those comments are comparisons about Perl and Python (and stuff like "Python is better than Perl")
I am wondering if PHP isnt in competition ? I have a good feeling using PHP, but Im not really in Python/Perl so Id like to get a small overview about those languages.
