CODE

<?php
function code( $input ){

$data[0] = "<?php include(\"shoutbox.php?no=";
$data[1] = "\"); ?>";

$find[0] = "/\[b\](.*?)\[\/b\]/i";
$find[1] = "/\[url\=(.*)\](.*)\[\/url\]/";
$find[2] = "/\[u\](.*?)\[\/u\]/i";
$find[3] = "/\[i\](.*?)\[\/i\]/i";
$find[4] = "/\[big\](.*?)\[\/big\]/i";
$find[5] = "/\[small\](.*?)\[\/small\]/i";
$find[6] = "/\[shoutbox]id=(.*)\[\/shoutbox\]/";

$replace[0] = "$1";
$replace[1] = "<a href=\"$1\">$2</a>";
$replace[2] = "$1";
$replace[3] = "$1";
$replace[4] = "$1";
$replace[5] = "$1";
$replace[6] = "$data[0]$1$data[1]";

$change = preg_replace($find, $replace, $input);
print $change;
}
code("[shoutbox]id=1[/shoutbox]");
?>

In my code, the shoutbox doesnt work. The code is ment to replace [shoutbox]no= with <?php include("shoutbox.php?no= then replace [/shoutbox] with "); ?> which it does, but then the php code just appears in the sorce of the webpage. Does anyone know how to fix it?

Thanks

Wouldn't it be easier just to do this?

CODE

$string = '[shoutbox]id=1[/shoutbox]';
$string = str_replace ('[shoutbox]id=', '', $string);
$string = str_replace ('[/shoutbox]', '', $string);

include ('shoutbox.php?no=' . $string);

Using that you could create a seperate function:

CODE

function shoutbox_tag ($input) {

$string = strstr ($input, '[shoutbox]'); // Removes all parts of string that are NOT [shoutbox]...[/shoutbox]
$string = strstr ($string, '[/shoutbox]', true);
$string = $string . '[/shoutbox]'; // End remove

$string = str_replace ('[shoutbox]id=', '', $string);
$string = str_replace ('[/shoutbox]', '', $string);

return $string;

}

Which you would call as follows:

CODE

include ('shoutbox.php?no=' . shoutbox_tag('123123[shoutbox]id=1[/shoutbox]123123'));

If you want to execute a string as if it were PHP code, consider researching eval. Just be careful with this function, as you wouldn't want user input to be ran as PHP code, so you may need to properly verify the string before running eval.

BTW, you can't include files the way you want them to be included; that is, assigning _GET variables.

Is it possible when using PHP preg_replace, to include something, rather than displaying text. The code is below, the proplem is with the shoutbox.

CODE

<?php
function code( $input ){

$find[0] = "/\[b\](.*?)\[\/b\]/i";
$find[1] = "/\[url\=(.*)\](.*)\[\/url\]/";
$find[2] = "/\[u\](.*?)\[\/u\]/i";
$find[3] = "/\[i\](.*?)\[\/i\]/i";
$find[4] = "/\[big\](.*?)\[\/big\]/i";
$find[5] = "/\[small\](.*?)\[\/small\]/i";
$find[6] = "/\[shoutbox]id=(.*?)\[\/shoutbox\]/";

$replace[0] = "$1";
$replace[1] = "<a href=\"$1\">$2</a>";
$replace[2] = "$1";
$replace[3] = "$1";
$replace[4] = "$1";
$replace[5] = "$1";
$replace[6] = include("shoutbox.php?no=$1");
$change = preg_replace($find, $replace, $input);
echo $change;
}
code("[shoutbox]id=2[/shoutbox]");
?>

It doesnt replace the $1 with the shoutbox id and the error message is;

QUOTE

[b]Warning: include(shoutbox.php?no=$1) [function.include]: failed to open stream: No error in C:\wamp\www\replace\index.php on line 18

Even if it did replace the 1 variable, it still wouldn't work. As i've mentioned above, you cannot include files the way you want to. If you want to set $_GET['id'], you have to do so with the parent page.

Ok, but if im not just going to add a shoutbox code in there, i will post other tags like so then it wont work

Sorry for neglecting your topic

It does. That's what this part of the code does:

CODE

$string = strstr ($input, '[shoutbox]'); // Removes all parts of string that are NOT [shoutbox]...[/shoutbox]
$string = strstr ($string, '[/shoutbox]', true);
$string = $string . '[/shoutbox]'; // End remove

It removes all parts of input that are not [shoutbox]...[/shoutbox] and processes them separately. Unless you can see otherwise...

BTW, what truefusion is saying about including files (I don't think you understand - sorry if you do) is this:

You can't include a file like this:

CODE

include 'file.php?id=1';

And have the code in file.php as:

CODE

function ($_GET['id']);

It doesn't work. If you want to "give" a variable to an included file, you have to this:

CODE

$id = 1;
include 'file.php';

And have the code in file.php as:

CODE

function ($id);
