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.
JSON was based on a subset of the JavaScript scripting language (specifically, Standard ECMA-262 3rd Edition—December 1999 [11]) and is commonly used with JavaScript, but it is a language-independent data format.
Since JSON text sequences cannot contain control characters, a record separator character can be used to delimit the sequences. In addition, it is suggested that each JSON text sequence be followed by a line feed character to allow proper handling of top-level JSON objects that are not self delimiting (numbers, true, false, and null).
symbol: Unicode symbolic atoms (aka identifiers) blob: Binary data of user-defined encoding; clob: Text data of user-defined encoding; sexp: Ordered collections of values with application-defined semantics; Each Ion type supports a null variant, indicating a lack of value while maintaining a strict type (e.g., null.int, null.struct).
an atom is either a number or a symbol; a number is an unbroken sequence of one or more decimal digits, optionally preceded by a plus or minus sign; a symbol is a letter followed by zero or more of any characters (excluding whitespace); and; a list is a matched pair of parentheses, with zero or more expressions inside it.
