I have a text file called test.txt which is I am trying to get to load
into a webpage. This is simple enough, but I am trying to make it so
that it recognises certain formatting, similar to how wikipedia pages
work.
so, my text file contains ONLY the following:
This is /just/ some test text *to see* if the PHP works
and to /*evaluate*/ what it actually does
The intention is that /just/ will show as italic, *to see* will show as
bold and /*evaluate*/ will show as bold italic.
Creating the text inside the page works fine.
<?php
$s = 'hello. /this/ works *bolding* works. /*Both work*/!';
$search = array ( '@/(.*?)/@si',
'@\*(.*?)\*@si');
$replace = array ( '<i>\1</i>',
'<b>\1</b>');
echo preg_replace($search, $replace, $s);
?>
However when I try and read from a text file using
$s = file('./wiki.txt');
$search = array ( '@/(.*?)/@si',
'@\*(.*?)\*@si');
$replace = array ( '<i>\1</i>',
'<b>\1</b>');
echo preg_replace($search, $replace, $s);
?>
All that is shown is the single word 'Array'. This confuses me a lot as
<?
$s = file('./test.txt');
print_r($s);
?>
shows that the text is being read into the page
Array ( [0] => This is /just/ some test text *to see* if the PHP works
[1] => and to /*evaluate*/ what it actually does )
If someone can see what is going wrong here I would be most grateful.
Kind regards
Dan
