Strings

Strings
A string is series of characters, where a character is the same as a byte. This means that PHP only supports a 256-character set, and hence does not offer native Unicode support. See details of the string type.
Note: string can be as large as 2GB.

A string literal can be specified in four different ways:

•     single quoted
•     double quoted
•     heredoc syntax
•     nowdoc syntax (since PHP 5.3.0)
