maxdb_fetch_row -- maxdb_result::fetch_row — Get a result row as an enumerated array
过程化风格
$result
)面向对象风格
Returns an array that corresponds to the fetched row, or NULL
if there are no more rows.
maxdb_fetch_row() fetches one row of data from the result set represented by
result
and returns it as an enumerated array, where each column is stored
in an array offset starting from 0 (zero). Each subsequent call to the
maxdb_fetch_row() function will return the next row within the result set,
or FALSE
if there are no more rows.
maxdb_fetch_row() returns an array that corresponds to the fetched row
or NULL
if there are no more rows in result set.
Note: 此函数将 NULL 字段设置为 PHP
NULL
值。
Example #1 面向对象风格
<?php
$maxdb = new maxdb ( "localhost" , "MONA" , "RED" , "DEMODB" );
if ( maxdb_connect_errno ()) {
printf ( "Connect failed: %s\n" , maxdb_connect_error ());
exit();
}
$query = "SELECT name, state FROM hotel.city ORDER by zip" ;
if ( $result = $maxdb -> query ( $query )) {
while ( $row = $result -> fetch_row ()) {
printf ( "%s (%s)\n" , $row [ 0 ], $row [ 1 ]);
}
$result -> close ();
}
$maxdb -> close ();
?>
Example #2 过程化风格
<?php
$link = maxdb_connect ( "localhost" , "MONA" , "RED" , "DEMODB" );
if ( maxdb_connect_errno ()) {
printf ( "Connect failed: %s\n" , maxdb_connect_error ());
exit();
}
$query = "SELECT name, state FROM hotel.city ORDER by zip" ;
if ( $result = maxdb_query ( $link , $query )) {
while ( $row = maxdb_fetch_row ( $result )) {
printf ( "%s (%s)\n" , $row [ 0 ], $row [ 1 ]);
}
maxdb_free_result ( $result );
}
maxdb_close ( $link );
?>
