PHP uses the mysql_affected_rows() function to find how many rows were changed by the query. To illustrate this, we have the following example −
Example
<html>
<head>
<title>Rows affected by query</title>
</head>
<body>
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn ) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully<br />';
mysql_select_db( 'TUTORIALS' );
$result_id = mysql_query ($query, $conn_id);
# report 0 rows if the query failed
$count = ($result_id ? mysql_affected_rows ($conn_id) : 0);
print ("$count rows were affected</p><p>");
?>
</body>
</html>The above is the detailed content of How can we write a PHP script to count the number of rows affected by a MySQL query?. For more information, please follow other related articles on the PHP Chinese website!
