How to render different variables as you work your way down the page / through the script?

Question

I have a .php file that is rendering as a web page. Is there any way I could change a variable on the fly as the page renders?

Currently the page renders like this...

I love to eat oranges.
I love to eat oranges.
I love to eat oranges.

But I want it to render like this...

I love to eat oranges.
I love to eat apples.
I love to eat cheese.

Please see the sample code below...

<?php
$variable = "oranges";
?>

<?php
echo I love to eat $variable.
?>

<?php
$variable = "apples";
?>

<?php
echo I love to eat $variable.
?>

<?php
$variable = "cheese";
?>

<?php
echo I love to eat $variable.
?>

Answer 1

You're missing some quotes and semicolons:

<?php
$variable = "oranges";
?>

<?php
echo "I love to eat $variable.";
?>

<?php
$variable = "apples";
?>

<?php
echo "I love to eat $variable.";
?>

<?php
$variable = "cheese";
?>

<?php
echo "I love to eat $variable.";
?>

Here's another way to accomplish the same thing:

<?php
    $foods = array('oranges', 'apples', 'cheese');
    $index = 0;
    function getFood($next = FALSE) {
       if($next) {
           $str = $foods[++$index];
       } else {
           $str = $foods[$index];
       }
       return 'I love to eat ' . $str; 
    }
?>

...

<?php
    echo getFood();
?>

...

<?php
    echo getFood(true);
?>

...

<?php
    echo getFood();
?>

What is that, Programming 101?

<?php
foreach(array('apples','oranges','cheese') as $variable)
   echo "I love to eat $variable";
?>
