PHP使用mysql_affected_rows()函数来查找查询改变了多少行。为了说明这一点,我们有以下示例−
<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>
