Question

I have a table data and a few columns and I am trying to display the values of certain columns only. I wrote this below code but it is not working correctly. giving some error.

$daily = mysql_query("SELECT email, first_name, last_name AS dval FROM users");
while( $stat = mysql_fetch_assoc($daily)) 
{
    echo '<br/>' . " {$stat['dval']}";
}

Only the first_name of all the entries is being printed. How can I get the email and last name?

Answer 1

You need to execute the query with mysql_query():

$result = mysql_query( "SELECT email, first_name, last_name AS dval FROM `data`");
$row = mysql_fetch_assoc( $result);
echo $row['dval'];

I changed your variable names to use the common naming convention.

To get more than one row to print, use a while loop:

while( $row = mysql_fetch_assoc( $result)) {
    echo $row['dval'];
}

Note that the mysql_* functions are being deprecated, and you should switch to either mysqli or PDO.

Why would anything but $stat['dval'] print? You only said echo $stat['dval'];.

Add the things you want to print in the while loop:

while( $row = mysql_fetch_assoc( $result)) {
    // HERE is where you add the things you want to print
    echo $row['email'];
    echo $row['first_name'];
    echo $row['dval'];
}
