php简单实现查询数据库返回json数据
示例代码一:
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
//
设置返回json格式数据
header( "content-type:application/json;charset=utf8" );
//连接数据库
$link
= mysql_connect( "localhost" ,
"root" ,
"root" )
or
die ( "Unable
to connect to the MySQL!" );
mysql_query( "SET
NAMES "UTF8"" );
mysql_select_db( "jilinwula" ,
$link )
or
die ( "Unable
to connect to the MySQL!" );
//
获取分页参数
$page
= 0 ;
$pageSize
= 3;
if (! is_null ( $_GET [ "page" ]))
{
$page
= $_GET [ "page" ];
}
if (! is_null ( $_GET [ "pageSize" ]))
{
$pageSize
= $_GET [ "pageSize" ];
}
//
查询数据到数组中
$result
= mysql_query( "select
username,password from userinfo limit "
. $page
. ",
" .
$pageSize
. "" );
$results
= array ();
while
( $row
= mysql_fetch_assoc( $result
|
