README

Parse a string containing a full name into its parts (salutation, first name, middle names, initials, last name with prefixes, suffix, nickname).

Fork lineage. This is a fork of theiconic/name-parser (dormant since ~2020), built on top of the modernization done by codebyzach/name-parser. It adds casing- and credential-aware parsing and a confidence/ambiguity signal, and targets PHP 8.3+.

Why this fork

The upstream parser keys every token through strtolower() before matching it against its salutation/suffix dictionaries, so it cannot tell an all-caps credential from a same-spelled name. Two failure modes follow, both common in professional and clinician name lists:

A trailing credential without a comma swallows the surname: "Jane Doe DDS" parsed to last name "Dds" (the real surname lost).
A short credential token that is also a real name is mis-stripped: the Vietnamese surname "Do" and given name "Vi" were consumed as the credentials DO / VI.

This fork fixes both and adds an advisory confidence pass for the genuinely ambiguous cases.

What changed

Casing as a signal. An ambiguous token (Do, Vi, Ma, roman numerals, two-letter credentials) is treated as a credential only when written ALL-CAPS (DO, VI); Title- or lower-case keeps it as a name part. People write credentials in caps and names in title case, so the original casing carries the signal that lowercasing discarded.
Terminal-token guard. A lone name-colliding token in a comma given-name segment is kept as a name rather than emptied into a credential, unless its casing reads as a credential.
Confidence assessor. When a token matches a credential but the casing is uninformative (uniform-case input, or a lowercase token), Confidence::assess() flags the input so you can route it to manual review instead of trusting the split.
Expanded English dictionary (inherited from the CodeByZach fork): DDS, DO, DVM, PsyD, LCSW, MSW, MBA, EMBA, Esq, roman numerals VI to X, Hon., and more.
Nursing and allied-health credentials. RN, NP, PharmD, APRN, PA-C, OTR/L, and 30+ more, mined by frequency from the NPI registry, so a trailing credential no longer leaks into the first name.
Unclosed nickname delimiter. An opening ( or quote with no matching close no longer swallows the surname ("John (Bob Smith" keeps Smith).

Requirements

PHP 8.3+ (tested through 8.5)
ext-mbstring

Installation

composer require iliaal/nameparser

Usage

use Iliaal\NameParser\Parser;

$parser = new Parser();
$name = $parser->parse('Dr. Jane A. Doe DDS');

$name->getSalutation();   // "Dr."
$name->getFirstname();    // "Jane"
$name->getInitials();     // "A."
$name->getLastname();     // "Doe"
$name->getSuffix();       // "DDS"
$name->getFullName();     // "Jane A. Doe"

The full getter surface (getMiddlename(), getNickname(), getLastnamePrefix(), getGivenName(), getAll()) is unchanged from upstream.

Structured output

toArray() returns every part under a fixed key set, with an empty string for any part that is absent. Unlike getAll(), which omits empty parts and varies its keys, this shape is safe to consume without existence checks:

$parser->parse('Dr. Jane A. Doe DDS')->toArray();
// [
//   'salutation' => 'Dr.', 'firstname' => 'Jane', 'initials' => 'A.',
//   'middlename' => '', 'lastname_prefix' => '', 'lastname' => 'Doe',
//   'suffix' => 'DDS', 'nickname' => '', 'given_name' => 'Jane A. Doe',
//   'full_name' => 'Jane A. Doe',
// ]

Confidence / ambiguity

For batch imports where a wrong split is a data-integrity problem, check whether the input was decidable from its casing. The signal is available two ways: as a standalone pre-check on a raw string, or on the parsed result itself.

use Iliaal\NameParser\Confidence;

// pre-check, before parsing
$result = Confidence::assess('NGUYEN, VI');
// ['ambiguous' => true, 'notes' => ["'VI' could be a name or a credential; input casing is uniform"]]

// or read it off the parse; same signal, derived from the same input
$result = $parser->parse('NGUYEN, VI')->getConfidence();

if ($result['ambiguous']) {
    // queue the row for manual review instead of trusting the parse
}

getConfidence() is read-only and does not change what parse() returns; it is an advisory pass you opt into. A mixed-case input like "Nguyen, Vi" stays unflagged; the title-case Vi resolves to the given name.

All-caps limitation. Disambiguation keys off casing, so uniform-case input (all-caps legacy and registry data, or all-lowercase) carries no signal: an ambiguous trailing token reads as a credential by default. The confidence pass flags these when the token plausibly collides with a real name (Do, Vi, Ma, roman numerals, MBA), so you can route them to review. Clean credentials that are not also names (RN, PT, OD) are left unflagged to keep review volume manageable on all-caps datasets.
