<?php
    public function yylex6()
    {
        if (!isset($this->yy_global_pattern6)) {
            $this->yy_global_pattern6 = $this->replace("/\G(\"\"\"(?=[ \t\r]*[\n#;]))|\G([\S\s])/isS");
        }
        if (!isset($this->dataLength)) {
            $this->dataLength = strlen($this->data);
        }
        if ($this->counter >=  $this->dataLength) {
            return false; // end of input
        }
        
        do {
            if (preg_match($this->yy_global_pattern6,$this->data, $yymatches, 0, $this->counter)) {
                if (!isset($yymatches[ 0 ][1])) {
                   $yymatches = preg_grep("/(.|\s)+/", $yymatches);
                } else {
                    $yymatches = array_filter($yymatches);
                }
                if (empty($yymatches)) {
                    throw new Exception('Error: lexing failed because a rule matched' .
                        ' an empty string.  Input "' . substr($this->data,
                        $this->counter, 5) . '... state TRIPPLE');
                }
                next($yymatches); // skip global match
                $this->token = key($yymatches); // token number

It seems like key($yymatches) can also be of type string. However, the property $token is declared as type integer. Maybe add an additional type check?

                $this->value = current($yymatches); // token value
                $r = $this->{'yy_r6_' . $this->token}();
                if ($r === null) {
                    $this->counter += strlen($this->value);
                    $this->line += substr_count($this->value, "\n");
                    // accept this token
                    return true;
                } elseif ($r === true) {
                    // we have changed state
                    // process this token in the new state
                    return $this->yylex();
                } elseif ($r === false) {
                    $this->counter += strlen($this->value);
                    $this->line += substr_count($this->value, "\n");
                    if ($this->counter >=  $this->dataLength) {
                        return false; // end of input
                    }
                    // skip this token
                    continue;
                }            } else {
                throw new Exception('Unexpected input at line' . $this->line .
                    ': ' . $this->data[$this->counter]);
