<serialised value>, repeated for each association/pair in the array. Basic language constructs php generally follows c syntax, with exceptions and enhancements for its main use in web development, which makes heavy use of string manipulation Php variables must be prefixed by $ This allows php to perform string interpolation in double quoted strings, where backslash is supported as an escape character. Php php uses argc as a count of arguments and argv as an array containing the values of the arguments A significant extension to the language's type system is the addition of composite types
Union types in php 8.0 (e.g Int|string meaning either integer or string), [84] intersection types in php 8.1 (e.g Traversable&countable meaning the value must implement both the traversable and countable interfaces), [85] and disjunctive normal form. ^ the netstrings specification only deals with nested byte strings Anything else is outside the scope of the specification For example, 3.14 will be serialized to 3.140 000 000 000 000 124 344 978 758 017 532 527 446 746 826.
A query string commonly includes fields added to a base url by a web browser or other client application, for example as part of an html document, choosing the appearance of a page, or jumping to positions in multimedia content.
