create table test
	name varchar(20),
	gender varchar(20),
	salary varchar(20)
insert into test values ('nm1','male','20000');
insert into test values ('nm2','female','85000');
insert into test values ('nm3','male','1000');
insert into test values ('nm4','unknown',NULL);

I am new to PHP, just learning.

I've a sample data of my table. While showing data in front, for gender I've to show
only the first character i.e. m/f/u and for salary I've to sum the total amount from front i.e
by using PHP.

also in my table salary is in varchar would I've to parse it as number?

<pre lang="xml"><?php
        $result =mysql_query("select * from test")
            or die(mysql_error());
        echo "<table cellpadding = '10'>";
        echo "<tr>
                <th>total salary:</th>
        while($row = mysql_fetch_array($result))
            echo "<tr>";
            echo '<td>'.$row['name'].'</td>';
            echo '<td>'.$row['gender'].'</td>';
            echo '<td>'.$row['salary'].'</td>';

Solution 1

in gender you can use
echo '<table><tbody><tr><td>'.substr($row['gender'],0,1).'</td></tr></tbody></table>';
instead  of echo '<table><tbody><tr><td>'.$row['gender'].'</td></tr></tbody></table>';

and you don't have to change it to number or double. php will auto convert it

Thank you. What about getting the total sum of salary??

mean what you have all names are unique, each have unique salary value it's not monthly or any other period you have describe so they will give the values what you have entered if you want to get all sum value of salary you can use Sum

SELECT SUM(salary) FROM test

if you want to sum in php then set a variable like
before while and in while loop use
