It's indistinguishable so changing to array_fill_keys() is fine by me :)


$s = '';
while (!in_array($this->tokens[$this->index][Lexer::TYPE_OFFSET], $tokenType, true)) {
while (!isset($tokenTypeMap[$this->tokens[$this->index][Lexer::TYPE_OFFSET]])) {
$s .= $this->tokens[$this->index++][Lexer::VALUE_OFFSET];
}
return $s;
