I don't have any particular antipathy towards Python, but I have to say, I personally really like the '$' prepended on variable names, and I think PHP's nice simple way of dealing with that is much nicer than Perl, Bash, or TCL, for example, where there are ungainly additional rules as to what prepends a variable. It makes it easy to tell at a glance what is a variable in your code.
That, combined with 1) the ease of variable interpolation in strings via {$varname_or_expression}, 2) the concept of variable variable names, as in $$varname, and 3) even the concept of variable (conditional) function execution via $function_name() all combine to create some powerful scripting features.
