有没有比使用echo更好的显示结果的方法

Question

I posted in a previous question how to get my rating script to work. I have now finally got it to work using maths rather than the avg function but i still have two questions to ask.

Q1) Is there a better way of displaying my results other than using echo all the time

Q2) How do i add in my other three performance values in to this script they are all in the same table

<?php
mysql_connect("localhost", "username", "password") or die ("sorry we could not connect to our servers");
mysql_select_db("db") or die ("sorry we could not our database");

$find_data = mysql_query("SELECT * FROM rating");

while($row = mysql_fetch_assoc($find_data))
{
$id = $row['id'];
$current_rating = $row['Reliability_timekeeping'];
$reviews = $row['reviews'];
$new_rating = $current_rating / $reviews;
echo "($reviews Reviews)";
echo "Reliability & timekeeping: ";
echo round($new_rating,1);
echo "/10";
}
?>

sorry for my writing skill writing is not my strong point and still new to php

Answer 1

To avoid using echo all the time, you can just accumulate all the output in a variable and use a single echo. As a good practice, in my scripts I try to use just one echo at the script end. This will make each page a few mili-seconds faster, as less PHP / web server interactions will be necessary:

$Response = "";
$Response .= "($reviews Reviews)".
             "Reliability & timekeeping: ".round($new_rating,1)."/10";

...
more code
...

echo $Response;

Just indent and break lines in a way that the code gets readable, and everything will be fine.
