以数据库中的纯文本（而不是数组）显示用户的名字和姓氏

Question

I have a html page that sends value phone to log.php:

<?php 
    $PHONE = $_POST['phone'];

    mysql_connect('host.com', 'user', 'pass'); mysql_select_db('userdb');  

    $results = mysql_query(sprintf("SELECT FNAME,LNAME FROM `details` WHERE PHONE='$PHONE'",
                             mysql_real_escape_string($PHONE))) or die(mysql_error()); 
    while($row = mysql_fetch_assoc($results))
    { 
        $rows[1] = $row; 
    }
    print_r($rows)
?>

I get the result in log.php file in the form of an array from the database-

Array ( [1] => Array ( [FNAME] => Vikrant [LNAME] => Kelkar ) ) 

I have table 'details' created

FNAME-First name

LNAME-Lastname

BIRTHDAY-Birthday

PHONE- user's no.

My Question is , I want to just display ' Vikrant Kelkar ' as a result in log.php file , and not the whole array but just the First & Last Name of user. Any help would be greatfull ?

Answer 1

只需访问数组：

echo $rows[0]["FNAME"] . " " . $rows[0]["LNAME"];

Answer 2

you do not need to make it into an array unless you have more than one result.

  while($row = mysql_fetch_assoc($results))
        { 
        $full_name = $row['FNAME'].' '.$row['LNAME']; 
        //$full_name[] = $row['FNAME'].' '.$row['LNAME']; // multi result
        }

echo $full_name;
//echo $full_name[0]; // loop thro foreach

think about learning pdo/mysqli as the mysql library will not function in php soon.

Answer 3

Why you are using while loop. SQL WHERE clause condition is phone number so it will be unique and return only one row.therefore,just remove while loop and do simply the following.

<?php 
$PHONE = $_POST['phone'];

mysql_connect('host.com', 'user', 'pass'); mysql_select_db('userdb');  

$results = mysql_query(sprintf("SELECT FNAME,LNAME FROM `details` WHERE PHONE='$PHONE'",mysql_real_escape_string($PHONE))) or die(mysql_error()); 
$row = mysql_fetch_assoc($results);
echo $row['FNAME']." ".$row['LNAME'];

?>

Answer 4

You can MySQL's CONCAT function to build the full name when querying the database. For example:-

<?php 
mysql_connect('host.com', 'user', 'pass'); mysql_select_db('userdb');  

$results = mysql_query(sprintf(
    "SELECT CONCAT(FNAME, ' ', LNAME) AS NAME FROM `details` WHERE PHONE='%s';",
    mysql_real_escape_string($_POST['phone'])
));

$rows = array();

if($results)
{
    while($row = mysql_fetch_assoc($results))
    { 
        $rows[] = $row; 
    }
}

print_r($rows)
?>
