First, you need to define a database interface function, which can be stored separately as a php page.
II
On another php page, you must first useInclude function
Including the above php page, that is, you must ensure that the above interface functions can be correctly called
Query ("SELECT * FROM t_order WHERE seller_id = '". $ seller_id. "'"); // query data echo $ result-> num_rows; // Number of output rows}?>
You can call the defined function to display the number of rows in the SQL query result.$result = $conn->query("SELECT * FROM t_order WHERE seller_id= '". $seller_id."' ");
Query and query databasest_seller
Tableseller_id
Equal$seller_id
And assign the result set$result
And then use$result->num_rows
Number of rows that can obtain the query result.echo
Output Display
'). AddClass ('pre-numbering '). hide (); $ (this ). addClass ('Has-numbering '). parent (). append ($ numbering); for (I = 1; I <= lines; I ++) {$ numbering. append ($ ('
'). Text (I) ;}; $ numbering. fadeIn (1700) ;}) ;}; script
The above describes 1. PHP-the number of rows that obtain the MySQL database query results, including the Mysql database content. I hope my friends who are interested in the PHP Tutorial will be helpful.
