根据下面的代码,我用于常规的mysql,我怎么能将它转换为使用mysqli？
是否像更改**mysql _query($ sql)一样简单 ; 到mysqli _query($ sql) ; ？**
<?PHP
//in my header file that is included on every page I have this
$DB["dbName"] = "emails";
$DB["host"] = "localhost";
$DB["user"] = "root";
$DB["pass"] = "";
$link = mysql_connect($DB['host'], $DB['user'], $DB['pass']) or die("<center>An Internal Error has Occured. Please report following error to the webmaster.<br><br>".mysql_error()."'</center>");
mysql_select_db($DB['dbName']);
// end header connection part
// function from a functions file that I run a mysql query through in any page.
function executeQuery($sql) { …如果没有这样的表,我想通过app创建表.但是第一次这样做......需要一些帮助,所以
//connecting...
$mysqli = new mysqli($db_params['host'], $db_params['login'], $db_params['pass'], $db_params['name']);
if ($mysqli->query("SHOW TABLES LIKE `products`")){
echo ' YES';
} else echo 'no';
它总是说NO.
