在超出页面大小的行中显示大字符串(FPDF)

I want to show the following array in a line without break.

$header = array('Sl.', 'Session.', 'Time','Filename','Operator Name','Mobile No.','Amount','SSL Status','SSL Time','Operator Status','Op.Time','Reversal Reqd.?');

But it exceeds the page size.

Please help me.

    I've used this extension to the FPDF class. It introduces the MultiCell method (for my convenience wrapped in the OutputLines method). In this method you can specify the maximum number of lines. Any part of the string that won't fit, will be returned from the function. In that case you can create a new function and call MultiCell again, until it returns ''.

    <?
    
    require 'fpdf.php';
    // Class voor implementate van handige aanvullende features.
    class EPDF extends FPDF {
    
        function MultiCell($w, $h, $txt, $border=0, $align='J', $fill=false, $maxline=0)
        {
            //Output text with automatic or explicit line breaks, at most $maxline lines
            $cw=&$this->CurrentFont['cw'];
            if($w==0)
                $w=$this->w-$this->rMargin-$this->x;
            $wmax=($w-2*$this->cMargin)*1000/$this->FontSize;
            $s=str_replace("",'',$txt);
            $nb=strlen($s);
            if($nb>0 && $s[$nb-1]=="
    ")
                $nb--;
            $b=0;
            if($border)
            {
                if($border==1)
                {
                    $border='LTRB';
