Constants

Output modes

Every data-returning method accepts an optional $output argument.

Constant	Value	Returns
JsonFast::OUTPUT_ARRAY	0	PHP array (default)
JsonFast::OUTPUT_STRING	1	JSON string
JsonFast::OUTPUT_OBJECT	2	stdClass for JSON objects

$data   = JsonFast::minify($json);                           // array
$string = JsonFast::minify($json, JsonFast::OUTPUT_STRING); // string
$object = JsonFast::minify($json, JsonFast::OUTPUT_OBJECT);  // stdClass

TIP

OUTPUT_OBJECT only affects JSON objects. JSON arrays are always returned as PHP arrays.

Repair flags

Pass to repair() as a bitmask. Combine with bitwise OR (|).

Constant	Description
REPAIR_BOM	Strip UTF-8 byte order mark
REPAIR_JSONP	Strip JSONP wrapper (callback(...))
REPAIR_COMMENTS	Remove // and /* */ comments
REPAIR_TRAILING_COMMAS	Remove trailing commas
REPAIR_DOUBLE_ENCODED	Unwrap double-encoded JSON strings
REPAIR_UNQUOTED_STRINGS	Quote unquoted string values
REPAIR_SINGLE_QUOTES	Convert single quotes to double quotes
REPAIR_UNQUOTED_KEYS	Quote unquoted object keys
REPAIR_ALL	All repair flags combined

$flags = JsonFast::REPAIR_COMMENTS | JsonFast::REPAIR_TRAILING_COMMAS;
$fixed = JsonFast::repair($broken, $flags);

analyse() returns suggested flags with their bit values so you can build a targeted mask instead of using REPAIR_ALL.
