Syntax Conventions (cont)
A significant difference between Perl and PHP:
-
@ and % for arrays/hashes, $ for scalars
Generally, Perl shares many syntax conventions with PHP *:
-
$ to introduce (scalar) variables
- single/double-quote distinction on string constants
- multi-line strings and here-documents
- interpolation of variable values into strings
* Perl thought of them; PHP (and others) borrowed them
