PHP - Eregi_replace To Preg_replace Error

    $customer_contact_id = preg_replace("`", "", $customer_contact_id);

Am I doing something wrong? Every page that used the eregi_function, I changed to have it utilize the preg_function (because I saw a Youtube video telling me to do so). Now, every variable I perform the above on acts as if it doesn't exist. This has totally destroyed my system. What do I need to do here to fix things?

Hi,

Since upgrading to php 5.3 i have a line of code on  my site that is giving me a depreciated error. The line of code is as follows:

$data=eregi_replace(">"."[[:space:]]+"."<","><",$data);

I've got as far as knowing i need to change it from eregi_replace to preg_replace but i can't for the life of me work out where to put any backslashes etc, if any. Is there a formula for working this type of thing out? Every example i see has backslashes and $1's all over the place. Do i simply do this "/ and this /" after and before every double quote? Or is it not as simple as that? Things never are are they!

Please could an expert on here offer me any assistance. This is an important line of code(i think) so i didn't want to experiment as i would normally do, i need to get this right first time as i don't know what will happen if i get this wrong.

Cheers.

I have this function:
    function bbcode($input){
        $input = strip_tags($input);
        $input = htmlentities($input);
        
        $search = array(
                    '/\[b\](.*?)\[\/b\]/is',
                    '/\[i\](.*?)\[\/i\]/is',
                    '/\[u\](.*?)\[\/u\]/is',
                    '/\[img\](.*?)\[\/img\]/is',
                    '/\[url=http://(.*?)\](.*?)\[\/url\]/is',
                    '/\[font color=(.*?) size=(.*?) face=(.*?)\](.*?)\[\/font\]/is',
        );
        
        $replace = array(
                    '<b>$1</b>',
                    '<i>$1</i>',
                    '<u>$1</u>',
                    '<img src="$1">',
                    '<a href="$1">$2</a>',
                    '<font style="color:$1;font-size:$2;font-face:$3">$4</font>',
        );
        
        return preg_replace($search,$replace,$input);
    }
Now when i use this command($komentar is variable which is loaded from mysql):
echo bbcode($komentar);
it shows me this error:
Warning: preg_replace() [function.preg-replace]: Unknown modifier '/' in /home/dotars/public_html/includes/functions.php on line 212

What is wrong here ? :S

I currently have some custom tags, similar to BBCode, to be used for comments on my site. I'm trying to create a [nobr] tag (note: I know the no break tag will work in many major browsers, but it's deprecated, so I'm trying to be compliant).

The idea is that if I encounter the [nobr] tag, I need to remove all line breaks. Here's the best I can do, but it's not working as I had hoped.

Here's what I currently use to replace line breaks with a break tag.
Code: [Select]
$str=str_replace("\r\n","<br>",$str);

Here's my attempt at introducing this new tag.
Code: [Select]
function BbToHtml($str) {

 $before=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\1",$str);
 $during=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\2",$str);
 $after=preg_replace("/(.+)\[nobr\](.+)\[\/nobr\](.+)/Usi","\\3",$str);

 $during=str_replace("\r\n","",$during);

 if($during != "") { // If the [nobr] tag was found, go with the new string.
  $str = $before.$during.$after;
 }
 else { // If the [nobr] tag was not found, go ahead like normal.
  $str=str_replace("\r\n","<br>",$str);
 }

 return $str;

I can't get that working. Any ideas on how to fix that, or a completely alternate method of doing it? Thank you!
