String Replace Function

Cheez

[Edited with "noparse" tags so code would display correctly -- NogDog]

Hello all,

I'm working on a simple thing to change BBcode to html code, for the URL bbcode. It's coming from a form where, in this instance, the input is $text. When I put this in, however, it gives me nothing in return. I don't honestly know where I've gone wrong, other than the fact that i haven't written in a loop yet.

[noparse]
<?php

$text = "blahblah[url=HYPERLINK]LINKTEXT[/url]blahblah[url=HYPERLINK]LINKTEXT[/url]blahblahblah";

function hyperlinks($text)
  {
	$startofstring = substr($text, 0, strpos($text, "[url"));
	$endofstring = strstr ($text, "[/url]");
	$endofstring = str_replace("[/url]", "", $endofstring );

$newstring = strstr ($text, "[url=");
$newstring = substr($newstring, 0, strpos($newstring, "[/url]"));
$newstring = $newstring . "</a>";
$newstring = str_replace("[url=", "<a href='", $newstring );
$newstring = str_replace("]", "' target='_blank'>", $newstring );

$new = $startofstring . $newstring . $endofstring;
  }

if(strstr($text,"[url=")) {
	$text = hyperlinks($text);
} else {
	echo $text;
}

?>
[/noparse]

Any help would be greatly appreciated!

Thanks,

Unless you have to reinvent the wheel, I would suggest a pear package.

Is your function not supposed to return anything?

yes. correct advice.

Or use for example a few parts of this BBCode function
bbcode-format-function:
http://www.phpit.net/code/bbcode-format-function/

Here is an article, also at www.phpit.net
Create your own BBCode, using PHP

It begins and ends like this

<?php
function bbcode_format ($str) {
    $str = htmlentities($str);

$simple_search = array(
            '/\[b\](.*?)\[\/b\]/is',                                
            '/\[i\](.*?)\[\/i\]/is',             
// snip
    $simple_replace = array(
                '<strong>$1</strong>',
                '<em>$1</em>',
// snip
    // Do simple BBCode's
    $str = preg_replace ($simple_search, $simple_replace, $str);
// snip

return $str;
}


////////// usage

$html_result = bbcode_format ( $str );


?>
