范例

Example #1 面向对象风格

  <?php
 
 $mysqli  = new  mysqli ( "localhost" ,  "my_user" ,  "my_password" ,  "world" );

 
 if ( mysqli_connect_errno ()) {
     printf ( "Connect failed: %s\n" ,  mysqli_connect_error ());
    exit();
}

 $mysqli -> query ( "CREATE TABLE myCountry LIKE Country" );
 $mysqli -> query ( "INSERT INTO myCountry SELECT * FROM Country" );


 $query  =  "SELECT Name, Code FROM myCountry ORDER BY Name" ;
if ( $stmt  =  $mysqli -> prepare ( $query )) {

     
     $mysqli -> query ( "DROP TABLE myCountry" );

     
     $stmt -> execute ();
    
    echo  "Error:\n" ;
     print_r ( $stmt -> error_list );

     
     $stmt -> close ();
}

 
 $mysqli -> close ();
 ?>

Example #2 过程化风格

  <?php
 
 $link  =  mysqli_connect ( "localhost" ,  "my_user" ,  "my_password" ,  "world" );

 
 if ( mysqli_connect_errno ()) {
     printf ( "Connect failed: %s\n" ,  mysqli_connect_error ());
    exit();
}

 mysqli_query ( $link ,  "CREATE TABLE myCountry LIKE Country" );
 mysqli_query ( $link ,  "INSERT INTO myCountry SELECT * FROM Country" );


 $query  =  "SELECT Name, Code FROM myCountry ORDER BY Name" ;
if ( $stmt  =  mysqli_prepare ( $link ,  $query )) {

     
     mysqli_query ( $link ,  "DROP TABLE myCountry" );

     
     mysqli_stmt_execute ( $stmt );
    
    echo  "Error:\n" ;
     print_r ( mysql_stmt_error_list ( $stmt ));

     
     mysqli_stmt_close ( $stmt );
}

 
 mysqli_close ( $link );
 ?>

以上例程会输出：

Array
(
    [0] => Array
        (
            [errno] => 1146
            [sqlstate] => 42S02
            [error] => Table 'world.myCountry' doesn't exist
        ))
