PHP寫緩衝_PHP教程

//寫入緩衝
$menu_query = exequery( $connection, " SELECT ct.id as tid, ct.type_name , mb.id, mb.cookname,
mb.price, mb.description, mb.pinyin FROM cook_type ct LEFT JOIN menubook mb ON ct.id = mb.cook_type WHERE
mb.id = ".$cook_id);

$row[pinyin] = ChangeToPinyin(iconv("utf-8","gb2312",$cook_name),1);

if( file_exists( "./menubook.php") )
{
require_once( "./menubook.php" );
}


if( is_array( $menu_cache) && !empty( $menu_cache) )
{
$classnum = count( $menu_cache );

二、添加菜單，寫入緩衝

$str=ChangeToPinyin(iconv("utf-8","gb2312",$cook_name),1);
$query_cook_add="insert into menubook(cookname,price,cook_type,description,pinyin) values(".$cook_name.",".$cook_price.",".$cook_type.",".$description.",".$str.")";
$cursor_cook_add=exequery($connection,$query_cook_add);
$cook_id = mysql_insert_id();

$menutype_query = exequery( $connection, " SELECT type_name FROM cook_type WHERE id = ".$cook_type);
$menutype_result = mysql_fetch_array( $menutype_query );


//本次菜單
$row[mid] = $cook_id;
$row[menu_name] = $cook_name;
$row[description] = $description;
$row[menu_price] = $cook_price;
$row[pinyin] = $str;

if( file_exists( "./menubook.php") )
{
require_once( "./menubook.php" );
}

if( is_array( $menu_cache) && !empty( $menu_cache) )
{
$classnum = count( $menu_cache );
$unmatchnum = 0;
for ( $i=0; $i<$classnum; $i++ )
{
if( $cook_type != $menu_cache[$i][tid] )
{
$unmatchnum++;
continue;
}
else //找到分類 ,添加改產品菜品的緩衝
{
$menu_cache[$i][list][] = $row;
}

}
if( $classnum == $unmatchnum ) //未找到分類
{
$type_row[tid] = $cook_type;
$type_row[type_name] = $menutype_result[type_name];
$type_row[list][0] = $row;

$menu_cache[] = $type_row;

}
}

else { //數組的產生
$type_row[tid] = $cook_type ;
$type_row[type_name] = $menutype_result[type_name];
$type_row[list][0] = $row;
