   echo $category;
  $cat= "'".implode("','", $category[0])."'";
    echo $cat;

 $con->query("SET NAMES 'utf8'");

     $sql="SELECT c.ad_id FROM `category_rel` c INNER JOIN tbl_category_master d ON c.category_id= d.fld_category_id WHERE d.fld_category_name IN ($cat)";
    $result1=$con->query($sql);

  while ($row = mysqli_fetch_assoc($result1)) {
    $output[] = $row;
 }
   echo json_encode(array("result"=>$output));
  $ids[]=json_encode(array($output));


      $stmtsearch="SELECT a.title, a.phone, a.description, a.email, a.post_date FROM `ad_master` a INNER JOIN tbl_city_master b ON a.city_id = b.fld_city_id WHERE b.fld_city_name = '$city' AND a.id IN ('2','11','28') ORDER BY id" ;

  $resultsearch=$con->query($stmtsearch);
     $json=array();
    while($row=mysqli_fetch_array($resultsearch)){

   array_push($json, 
  array('title'=> $row[0],
      'phone'=> $row[1],

Here it is:

<?php

$category = [["English","French","Spanish","German"]];

$inCategory = '"' . implode('","', $category[0]) . '"';

$sql = "SELECT a.ad_id FROM `category_rel` a INNER JOIN tbl_category_master b ON a.category_id= b.fld_category_id WHERE b.fld_category_name IN ($inCategory)";

echo $sql;

No sir,it doesn't work.. it show invalid argument passed in implode @Julie Pelletier

That's probably because the information your provided showing two layers of arrays is not right. Try it without the [0] and tell me if it works.

You can use $category array into IN clause query by using implode() function as

 $category= [["English","French","Spanish","German"]];
 $cat= "'".implode("','", $category[0])."'";// return 'English','French','Spanish','German'
 $query="SELECT a.ad_id FROM `category_rel` a INNER JOIN tbl_category_master b ON a.category_id= b.fld_category_id WHERE b.fld_category_name IN ($cat)"; // pass your cat here

You can use implode function with ',' delimiter.

$categoryCondition = implode(",", $category);
