要访问查询$ catarray的数据

Question

SELECT PM.*, promotion_type.type_name, country.country_name, province.province_name, 
    region.region_name, towncity.towncity_name FROM promotion As PM 
     join country on PM.country_id=country.id 
     join province on PM.province_id=province.id 
     join region on PM.region_id=region.id 
     join towncity on PM.towncity_id=towncity.id 
     join promotion_type on PM.promotion_type=promotion_type.id 
     where PM.category_id in('".$catarray."')"; 

Answer 1

由于$catarray使用，这可能帮助你 -

PM.category_id in('".implode(",", $catarray."')) 

$array = array('lastname', 'email', 'phone'); 
$comma_separated = implode(",", $array); 

echo $comma_separated; 

的放出来会 - lastname,email,phone
