FPDF WriteHtml align justify

Hello experts, can someone help me to find a solution for my problem

I have used fpdf to create a pdf file. I used html write function to style my text. However, i cannot justify my text like how multicell do when it breaks to new line. I have stuck for this problem for a few days and need a solution immediately .

Can someone look up for my code:

function WriteHTML($html)
    {
		
		//$this->Write(5,stripslashes(txtentities($e)),'FJ');
        //HTML parser
        $html=str_replace("\n",' ',$html);
        $a=preg_split('/<(.*)>/U',$html,-1,PREG_SPLIT_DELIM_CAPTURE);
        foreach($a as $i=>$e)
        {
            if($i%2==0)
            {
                //Text
                if($this->HREF)
                    $this->PutLink($this->HREF,$e);
                elseif($this->ALIGN=='justify')
                    $this->Cell(0,5,$e,0,1,'C');
                else
                    $this->Write(5,$e);
            }
            else
            {
                //Tag
