I am able to get both the value and row of the mysql query result.

But I am struggling to get the single output of a query. e.g.:

$result = mysql_query("SELECT COUNT(*) FROM Students;");

I need the result to display. But I am not getting the result.

I have tried with the following methods:

1. mysql_fetch_assoc()
2. mysql_free_result()
3. mysql_fetch_row()

But I didn't succeed to display (get) the actual value.

You need to alias the aggregate using the as keyword in order to call it from mysql_fetch_assoc

$result=mysql_query("SELECT count(*) as total from Students"); $data=mysql_fetch_assoc($result); echo $data['total'];

If you only need the value:

$result = mysql_query("SELECT count(*) from Students;"); echo mysql_result($result, 0);

$result = mysql_query("SELECT COUNT(*) AS `count` FROM `Students`"); $row = mysql_fetch_assoc($result); $count = $row['count'];

Try this code.

Please start using PDO.

mysql_* is deprecated as of PHP 5.5.0 and will be removed entirely in 7. Let's make it easier to upgrade and start using it now.

$dbh = new \PDO($dsn, $user, $password); $sth = $dbh->prepare('SELECT count(*) as total from Students'); $sth->execute(); print_r($sth->fetchColumn());

here is the code for showing no of rows in the table with PHP

$sql="select count(*) as total from student_table"; $result=mysqli_query($con,$sql); $data=mysqli_fetch_assoc($result); echo $data['total'];

$num_result = mysql_query("SELECT count(*) as total_count from Students ") or exit(mysql_error()); $row = mysql_fetch_object($num_result); echo $row->total_count;

You can as well use this and upgrade to mysqli_ (stop using mysql_* extension...)

$result = mysqli_query($conn, "SELECT COUNT(*) AS `count` FROM `Students`"); $row = mysqli_fetch_array($result); $count = $row['count']; echo $count;

With mysql v5.7.20, here is how I was able to get the row count from a table using PHP v7.0.22:

$query = "select count(*) from bigtable"; $qresult = mysqli_query($this->conn, $query); $row = mysqli_fetch_assoc($qresult); $count = $row["count(*)"]; echo $count;

The third line will return a structure that looks like this:

array(1) { ["count(*)"]=>string(4) "1570" }

In which case the ending echo statement will return:

1570

For mysqli users, the code will look like this:

$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name); $result = $mysqli->query("SELECT COUNT(*) AS Students_count FROM Students")->fetch_array(); var_dump($result['Students_count']);

or:

$mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name); $result = $mysqli->query("SELECT COUNT(*) FROM Students")->fetch_array(); var_dump($result[0]);

$db = new PDO('mysql:host=localhost;dbname=java_db', 'root', 'pass'); $Sql = "SELECT count(*) as `total` FROM users"; $stmt = $db->query($Sql); $stmt->execute(); $total = $stmt->fetch(PDO::FETCH_ASSOC); print '<pre>'; print_r($total); print '</pre>';

Result:

$howmanyuser_query=$conn->query('SELECT COUNT(uno) FROM userentry;'); $howmanyuser=$howmanyuser_query->fetch_array(MYSQLI_NUM); echo $howmanyuser[0];

after the so many hours excellent :)
