Simple way to read single record from MySQL

Question

What\'s the best way with PHP to read a single record from a MySQL database? E.g.:

SELECT id FROM games

I was trying to find an answer in t

Answer 1

$id = mysql_result(mysql_query("SELECT id FROM games LIMIT 1"),0);

Answer 2

The easiest way is to use mysql_result. I copied some of the code below from other answers to save time.

$link = mysql_connect('localhost','root','yourPassword')
mysql_select_db('database',$link);
$sql = 'SELECT id FROM games'
$result = mysql_query($sql,$link);

$num_rows = mysql_num_rows($result);

// i is the row number and will be 0 through $num_rows-1
for ($i = 0; $i < $num_rows; $i++) {
    $value = mysql_result($result, i, 'id');
    echo 'Row ', i, ': ', $value, "\n";
}

Answer 3

function getSingleRow($table, $where_clause="", $column=" * ",$debug=0) {
    $SelectQuery = createQuery($table, $where_clause, $column);

    $result = executeQuery($SelectQuery,$debug);
    while($row = mysql_fetch_array($result)) {
        $row_val = $row;
    }
    return $row_val;
}

Answer 4

'Best way' aside some usual ways of retrieving a single record from the database with PHP go like that:

with mysqli

$sql = "SELECT id, name, producer FROM games WHERE user_id = 1";
$result = $db->query($sql);
$row = $result->fetch_row();

with Zend Framework

//Inside the table class

$select = $this->select()->where('user_id = ?', 1);  
$row = $this->fetchRow($select);

Answer 5

I agree that mysql_result is the easy way to retrieve contents of one cell from a MySQL result set. Tiny code:

$r = mysql_query('SELECT id FROM table') or die(mysql_error());
if (mysql_num_rows($r) > 0) {
    echo mysql_result($r); // will output first ID
    echo mysql_result($r, 1); // will ouput second ID
}

Answer 6

at first : CREATE connection

$conn =  new mysqli('localhost', 'User DB', 'Pass DB', 'Table name');

and then get the record target :

$query = "SELECT id FROM games LIMIT 1"; // for example query
$result = $conn->query($query); // run query
if($result->num_rows){ //if exist something
    $ret = $result->fetch_array(MYSQLI_ASSOC); //fetch data
}else{
    $ret = false;
}
var_dump($ret);
