php代码重用。 有没有更好的方法呢？

Question

I have upgrade my code. In the old code I had 2 functions: display_maker_success() and display_maker_fail() but I realised I can combine those two functions into one display_maker_stat() by putting more arguments into the function. I like it very much!

Is better way to do this? I want more code reuse.

function display_maker_success($link, $userid){
    $status="closed";
    $result="completed";

    $sql = "select start, name from wuuk where tasker_id ='$userid' and status ='$status' and result ='$result' order by id desc LIMIT 6;";

    $result = mysql_query($sql, $link);
    $isempty=mysql_num_rows($result);
    If ($isempty ==0) {
        echo "No Record";
    } else {
        echo "<table border=1>";
        echo "<tr><th>Date & Time</th><th>Name</th><th>Status</th></tr>";
        while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
            echo "<tr><td>$row[0]</td><td>$row[1]</td><td>Completed</td></tr>";
        };
        echo "</table>";
    };
};

function display_maker_fail ($link, $userid) {
    $status="closed";
    $result="fail";

    $sql = "select start, name from wuuk where tasker_id ='$userid' and status ='$status' and result ='$result' order by id desc LIMIT 1;";
    $result = mysql_query($sql, $link);
    $isempty=mysql_num_rows($result);
    If($isempty ==0){
        echo "No Record";
    } else {
        echo "<table border=1>";
        echo "<tr><th>Date & Time</th><th>Name</th><th>Status</th></tr>";
        while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
            echo "<tr><td>$row[0]</td><td>$row[1]</td><td>fail</td></tr>";
        };
        echo "</table>";
    };
};

function display_maker_stat ($link, $userid, $reuslt, $limit) {
    $status="closed";
    $result="fail";

    $sql = "select start, name from wuuk where tasker_id ='$userid' and status ='$status' and result ='$result' order by id desc LIMIT 1;";
    $result = mysql_query($sql, $link);
    $isempty=mysql_num_rows($result);
    If($isempty ==0){
        echo "No Record";
    } else {
        echo "<table border=1>";
        echo "<tr><th>Date & Time</th><th>Name</th><th>Status</th></tr>";
        while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
            echo "<tr><td>$row[0]</td><td>$row[1]</td><td>$result</td></tr>";
        };
        echo "</table>";
    };
};

Try the below,

Also there were few errors in your code and i have corrected them.

function display_maker_stat($link, $userid, $reuslt = 'fail', $limit)
{
    $status = "closed";
    $html = '';
    $sql = "select start, name from wuuk where tasker_id ='$userid' and status ='$status' and result ='$result' order by id desc LIMIT 1;";
    $query = mysql_query($sql, $link);
    if (mysql_num_rows($query) != 0) {
        $html .= "<table border=1>";
        $html .= "<tr><th>Date & Time</th><th>Name</th><th>Status</th></tr>";
        while ($row = mysql_fetch_array($query, MYSQL_NUM)) {
            $html.= "<tr><td>$row[0]</td><td>$row[1]</td><td>$result</td></tr>";
        }
        $html.= "</table>";
        echo $html;
    }
    else {
        echo "No Record";
    }
}
