将表记录保存在php的关联数组中

Question

I have an associative array. After I select my records from my table (with two columns: objName,objCost), I want to save them in my array like this:

array(
      'objName'=>$row['objName'],
      'objCost'=>$row['objCost']
)

How should I do this?

This is my code:

$output = '';
$arr = array();
$sql = "SELECT * FROM obj WHERE objName LIKE '%" . $_POST["search"] . "%'";
$result = $db->query($sql) or die(mysql_error());
if ($result->rowCount() != 0) {
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
   //here i should insert my rows into my array        
}
$json_arr = json_encode($arr,JSON_UNESCAPED_UNICODE);
echo $json_arr;
} else {
echo 'Data Not Found';
}

According to your code,

$arr[] = ['objName'=>$row['objName'],'objCost'=>$row['objCost']];

Then you can encode the array and pick up the object on the other side with javascript or php. Which ever suits you

json_encode($arr);

In you Ajax success, get the objects and use the values as you deem fit

success: function (data) {data = JSON.parse(data); 

  for(var i = 0; i < data.length; i++){
    alert(data[i].objName);
   }
}
