It is not recommended to use mysql_connect, mysql_query and other functions in PHP5.3 and above versions. Instead, use the mysqli series (improved). This is an example of connecting to a database and querying data.

<?php
require &#39;conn.php&#39;;  //$link=mysqli_connect($host,$user,$pass,$database);

$query="select * from user_info";
if($result=mysqli_query($link,$query)){
	echo "query was successfully executed.".&#39;<br>';
	while($row=mysqli_fetch_assoc($result)){
		
		echo $row["name"]." ".$row["surname"].'<br>';
			}
	mysqli_free_result($result);
}
else{
	echo "the query is not executed.".'<br>';
}
mysqli_close($link);
?>
