The PhpToken class

(PHP 8)

Introduction

This class provides an alternative to token_get_all(). While the function returns tokens either as a single-character string, or an array with a token ID, token text and line number, PhpToken::tokenize() normalizes all tokens into PhpToken objects, which makes code operating on tokens more memory efficient and readable.

Class synopsis

class PhpToken implements Stringable {

/* Properties */

public int $id;

public string $text;

public int $line;

public int $pos;

/* Methods */

final public __construct(
    int $id,
    string $text,
    int $line = -1,
    int $pos = -1
)

public getTokenName(): ?string

public is(int|string|array $kind): bool

public isIgnorable(): bool

public __toString(): string

public static tokenize(string $code, int $flags = 0): array

}

id: One of the T_* constants, or an ASCII codepoint representing a single-char token.
text: The textual content of the token.
line: The starting line number (1-based) of the token.
pos: The starting position (0-based) in the tokenized string (the number of bytes).
