PHP文件为软DB？

Question

I want to use a PHP include file for a soft DB of about 20 elements. The actual data will be collected from RRD files and thus I prefer not to use MySQL just for 20 elements. The file fruits.php for the elements I'm trying something like:

<?php
$fruit="Apple"; $colour="red";
$fruit="Banana"; $colour="yellow";
$fruit="Pear"; $colour="green";
?>

In my recall file, results.php, I currenlty have the following code to recall the information from the fruits.php file:

<?php
include 'fruits.php';
$num=count($fruit);
$i = 0;
while ($i < $num){
echo "<p>My ".$fruit." is ".$colour.".</p>";
$i++;
}
?>

Since I'm not a proper scriptor/programmer, I'm quite blind to what should be different and stupid to proper coding. I have tried some other methods as well, one included:

$num=glob($fruit);

Any assistance with this will be really appreciated. Just to confirm the output I'd like for this code is to be:

My Apple is red.
My Banana is yellow.
My Pear is green.

Answer 1

in your case, variable $fruit will have a value "pear", and $colour = "green" Because you always redefine it

 <?php
 $fruits = array();
 $fruits[] = ["name" => "Apple", "colour"=>"red"];
 $fruits[] = ["name" => "Banana", "colour"=>"yellow"];
 $fruits[] = ["name" => "Pear", "colour"=>"green"];
 ?>

1st way:

<?php
include 'fruits.php';
$num=count($fruits);
$i = 0;
while ($i < $num){
echo "<p>My ".$fruits[$i]["name"]." is ".$fruits[$i]["colour"].".</p>";
$i++;
}
?>

2nd way (much easier):

<?php 
include 'fruits.php';
foreach ($fruits as $fruit){
  echo "<p>My ".$fruit["name"]." is ".$fruit["colour"].".</p>";
}

?>

where $fruit is element of the array $fruits
