Perl	PHP
Language features
Lexical scoping and dynamic scoping	Functions have unique scopes
3 different contexts (scalar, list, void)	No context types
5 different sigils - $,@,%,&,*	One sigil - $
Regular expressions part of the language	Regular expressions accessable through functions
Data
Scalars, Arrays, Hashes	Scalars, Arrays/Hash duality
Type-ignorant with roughly 3 types (string, number, reference)	Type-ignorant with roughly 13 different types (see. is_ functions)
Explicit references	Optional explicit references
Pass by value	Implicit (i.e it should do the right thing)
Functions
Can be called with 3 different syntaxes	Called with one syntax
Anonymous functions part of the language	Anonymous functions from create_function
Can be referenced	Symbolic calls
Args implicitly aliased to @_	Named args
Objects
Created through blessing a reference	Created through new Class
Multiple Inheiritance	Single Inheritance
Class variables aren't standard	Class variables part of the language

This is by no means exhaustive or entirely accurate but should give you some ideas of the fundamental differences between the two languages.

1. "Pass by value"? ' Don't think so.

sub addOne { $_[0]+=1 }
my $x = 1;
addOne($x);
print $x;

It's the assignment to the lexical variables that makes the parameter passing look like "pass by value".

2. "Class variables aren't standard"
What do you mean by this?

"Pass by ' Don't think so.

Yes, but what you're doing is explicitly accessing the argument list which is an array of aliases, which is somewhat of a hangover from earlier perls. But generally when you use the args passed into a subroutine you'll find that they were passed by value and not reference.

What do you mean by this?

In perl there's no standard way of creating or assigning class/object variables, whereas in PHP you can declare them with var $foo or create them with $this->foo = $thing and access them like so $this->foo.

Thank you for your Perl/PHP comparision chart! I just now learned how to read responses to my postings or I would have replied sooner. Again, Thanks!
