Module phpjson 

JSON re-encoding reproducing PHP’s json_encode($data, 0) applied to data coming from json_decode($json, true) (the JsonFile::parseJson -> JsonFile::encode pipeline, Composer 2.10.3, see docs/reference/JsonFile.php).

Byte-exact semantics:

• compact output ({"k":v}), insertion order preserved;
• / escaped as \/, non-ASCII as lowercase-hex \uXXXX (surrogate pairs beyond the BMP), controls \b \f \n \r \t then \u00XX;
• assoc quirk: an empty object becomes [], an object whose keys are exactly “0”..“n-1” in order becomes an array (PHP lost the object/array distinction at decode time);
• shortest round-trip floats (serialize_precision=-1): fixed notation without a trailing .0 for integral values (1.0 -> 1), exponential d[.ddd|.0]e±X outside (-4, 17]; see encode_double.

Structs

EncodeOptions

Options mirroring the json_encode flags used by Composer.

Constants

FLAGS_JSONFILE

JsonFile default (files written by Composer): JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE.

FLAGS_ZERO

Flags 0 (content-hash): compact, slashes and unicode escaped.

STDCLASS_MARKER

Sentinel key: an object reduced to this key encodes as {} (an empty stdClass on the PHP side, which the array semantics cannot express).

Functions

empty_stdclass

An empty object that will encode as {}.

php_double

smart_str_append_double with serialize_precision = -1: the shortest round-trip form PHP prints for a float (json_encode and serialize share it; the latter spells the exponent E).

php_json_encode
