php - convert an array into individual strings -


i have following arrays , convert each 1 of them individual strings. in other words, break array individual pieces.

  $formatsarray = $_post['formats'];       $topicsarray = $_post['topics'];

this because include individual strings in following query "

  $resources = "select * resources                     stage '%".$stage."%'                     , format '%".$formats."%'";         $run_query = mysqli_query($con, $resources);

this because format expect individual string comparison, such lets assume array ["video", "blogs", "articles"], wouldn't work if format compared video,blogs,articles rather video, blogs or articles.

i hope clear, , clarification, please advise.

all best,

update:

$formats = explode(',', $formatsarray);       $topics = explode(',', $topicsarray);         $resources = "select * resources                     stage '%".$stage."%'                     , format '%".$formats."%' , topic '%".$topics."%' ";

update:

$run_query = mysqli_query($con, $resources);     while($row = mysqli_fetch_array($run_query)) {      $data[] = array(       'format' => $row['format'],       'title' => $row['title'],       'costs' => $row['cost'],       'stage' => $row['stage'],       'topic' => $row['topic'],       'link' => $row['link']     );   }

update

  include('db.php');     $query = 'select * resources ';   $query .= 'stage :stage and';   $execute[':stage'] = '%' . $stage . '%';   if(!empty($_post['formats'])){   foreach($_post['formats'] $key => $format) {       $query .= 'format :format' . $key . ' , ';       $execute[':format' . $key] = '%' . trim($format) . '%';   }   }   if(!empty($_post['topics'])){   foreach($_post['topics'] $key => $topic) {       $query .= 'topic :topic' . $key . ' , ';       $execute[':topic' . $key] = '%' . trim($topic)  . '%';   }   }   $query = rtrim($query, ' , ');   if(!empty($execute)) {       $stmt = $con->prepare($query);       $stmt->execute($execute);   } else {       echo 'you must search something';   }         while($row = mysqli_fetch_array($query)) {          $data[] = array(           'format' => $row['format'],           'title' => $row['title'],           'costs' => $row['cost'],           'stage' => $row['stage'],           'topic' => $row['topic'],           'link' => $row['link']         );       }

ignoring necessity of prepared statements, do:

  $formats = implode('","', $formatsarray);   $topics = implode('","', $topicsarray);    $resources = "select * resources                 stage '%".$stage."%'                 , format in(".$formats.") , topic in(\"".$topics."\") ";

by adding " before , after each , when implode each array, array become e.g.

video","blogs","articles

so, need add " beginning , end of each in list. make final query like:

select * resources stage '%".$stage."%' , format in("video","blogs","articles") , ...
