echo and file_get_contents

kuujo · 01-19-2011, 01:22 AM

Two files:

test.php

Code:

$text

index.php

Code:

<?php
      $text = "something";
      $new = file_get_contents('test.php');
      echo $new;
?>

When I go to index.php it displays "$text", while I want it to display "something".

I'm trying to make simple template system, but when I try to read my templates with the above method, it displays php variables, not their values..

try this:

test.php

php Code:

test

index.php

php Code:

<?php
$test = 'something';
$new = trim(file_get_contents('test.php'));
$echo $$new,"\n";

that should work, because of how PHP look up variables and it lets you declare variable variables

That doesn't seem to work.

I'll explain some more.. I have some template files, that look like this:

HTML Code:

<div>
  <div id="left">{ value1 }</div>
  <div id="right">{ value2 }</div>
</div>

I also have template.php, which has function to change the { some_value } to $some_value.

In index.php I did:

PHP Code:


			
$new = replace_keywords(file_get_contents('content/main.tl'));

echo $new;

And I get all the names of $some_value, but not their values.

I tried your method, but it didn't work.

However.. I tried using eval and it worked. But I heard that it is not good to use eval, so what's the best solution for this?

I believe in KISS (Keep It Simple, Stupid!)

PHP Code:


			
$test = 'Something';
ob_start();
include 'content/main.tl';
echo ob_get_clean();

This method would require your template file to have and echo also:

PHP Code:


			
<?php echo $test; ?>

You could also faff around and make some kind of smarty type thingy, personally I think its a waste of time and resources, but hey hum.

PHP Code:


			
$test = 'something';
echo str_replace('$test', $test, file_get_contents('content/main.tl'));
