PDOstatement::execute() expect parameter 1 to be array, string given in - php

Question

Please help me to correct this code.
error at line
$stmt->execute($params = [], $query);
and when i open the file with dreamweaver every "$params=[]" is error.
-Databasse.php-
<?php
include_once('connection.php'); //my connection is here
class Database extends connection{
public function __construct(){
parent::__construct();
}
public function getRow($params = [], $query){
try {
$stmt = $this->datab->prepare($query);
$stmt->execute($params);
return $stmt->fetch();
} catch (PDOException $e) {
throw new Exception($e->getMessage());
}
}
public function getRows($query, $params = []){
try {
$stmt = $this->datab->prepare($query);
$stmt->execute($params);
return $stmt->fetchAll();
} catch (PDOException $e) {
throw new Exception($e->getMessage());
}
}
this is half of the source code database.php

Need to see more of the code - what is your query string, what array w/ what values are you trying to feed into it?
Typically your query will have question marks ? or might have keywords with colons :mykeyword as place holders for values, and then your array holds the values that are "prepared" and executed.
$query="select name from users where name=? and passwordHash=?";
$res=$connection->prepare($query);
$res->execute(array(
"myuser",
"dd02c7c2232759874e1c205587017bed"),
);
// OR
$query="select name from users where name=:name and passwordHash=:passwordHash";
$res=$connection->prepare($query);
$res->execute(array(
":name" => "myuser",
":passwordHash" => "dd02c7c2232759874e1c205587017bed"),
);
This does the query preparation, escaping, etc. and the "myuser" value replaces the first question mark and the hash string replaces the second.
