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)
