I want to Print some dynamically data from my function to passing string in function like this.

My Function

function mysql_funX_Repeter($query,$itemtemplet)
{
    $this->mysql_funX_connect();

    $result = mysql_query($query) or die("Repeter Query Error.");
    if (!$result) 
    {
        $message = 'ERROR:' . mysql_error();
        return $message;
    }
    else
    {
        $newtempelt = str_replace("Eval", '$row', $itemtemplet);
        while ($row = mysql_fetch_array($result)) 
        {

            echo $newtempelt;
        }
    }
}

Passing Value In Function

<ul>

<?php
$rptvalue="<li><a href=''>Eval['name']</a></li>";
$myFun->mysql_funX_Repeter("Select name from tbldemo",$rptvalue);
?>

</ul>

My Output

• $row['name']
• $row['name']
• $row['name']

I want Output

• prince
