PHP and MySQL - Get number of specific results from column - php

Question

I have this code for getting how many results there are in results there are in a column:
$result = "SELECT name FROM users";
echo $result;
How can I display a certain number of a specific string? For example, I want to search for the name "Andrew" in the column "name". There are 20 results for "Andrew". How can I echo out "20"?

Answer 1

You would COUNT them:
$result = "SELECT COUNT(`name`) AS `NameCount` FROM `users` WHERE `name` = 'Andrew'";
For all names you could do this:
SELECT `name`, count(`name`) AS `NameCount`
FROM `users`
GROUP BY `name`
Which would result in something like this:
name | NameCount
----------------------
Andrew | 20
Bob | 6
Carol | 125

If you will use Mysqli, you can use $num_rows. Somelithing like:
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if ($result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name")) {
/* determine number of rows result set */
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
/* close result set */
$result->close();
}
/* close connection */
$mysqli->close();
?>
also, you can use mysql count() function like:
$result = "SELECT count(*), name FROM users";
