Counting the rows in a table in PHP

Question

I want to count the number of rows in a table (using PHP and Mysql) all of the count() functions I can find only return columns, or array features, is there a function to return the number of rows? Many thanks!

Answer 1

you can count the number of rows returned by a query. note that this function is deprecated... it has options on the docs page here.

http://ca1.php.net/function.mysql-num-rows

Answer 2

You need to use mysqli_num_rows() :

$con=mysqli_connect("host","name","pass","database");

$sql="SELECT * FROM table_name";
$result=mysqli_query($con, $sql);
$rowcount=mysqli_num_rows($result);

$rowcount now stores the number of rows.

Answer 3

$count = mysql_num_rows($query);

将返回查询选择的行数，请确保您未在​​查询本身中使用count() 。

Answer 4

Depending if you are using mysql, mysqli or PDO query.

if mysql_query rkstar told you how to do it :

if mysqli_query : http://php.net/manual/fr/mysqli-stmt.num-rows.php

if PDO : do another query ! $rowCount = $db->query("SELECT FOUND_ROWS()")->fetchColumn();
