problems using ereg_replace

[Adamthenewbie]

I am trying to make a forum on my personal website and it's pretty much complete. I am just having problems with a couple little things.

How would I go about changing this text

to

<img src = "http://google.ca/images/logo.gif" border = "0" />

and

[ URL=http://www.google.ca]google.ca[/URL ] (modified a bit so you could see it)

to

<a href = "http://www.google.ca" target = "_blank">google.ca</a>

I have been trying to use ereg_replace but am having touble

$post = preg_replace('/\[img=([^\]]+)\]/i', "<img src=\"$1\" border=\"0\" />", $post);
$post = preg_replace('/\[url=([^\]]+)\](.*?)\[\/url\]/i', "<a href=\"$1\" target=\"_blank\">$2</a>", $post);

see how this works out for you. [man]preg_replace[/man] is a bit faster than the ereg_replace function.

thanks, that worked out good.

I now ran into another problem...

I want to also auto parse links. Say if someone types www.google.com it would automatically become a link. I got this from the PHP manual

$text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]",
                     "<a href=\"\\0\">\\0</a>", $text);

But it totally messes up images and links.

For example.

The link inside the img tag gets changed to a link so now I end up with this

<img src = "<a href = "http://google.com/images/logo.gif">" border = "0" />

Is there an easy solution for this or should I just not use the auto parsing links?

you could add a space to the beginning and end of that pattern, then it wont match things inside the bbcode tags. run that one first and then the bbcode ones second and it should work fine.

Stupid question but I am not really sure how to do this

I am confused by what alpha, almun mean... How would I go about adding a space to the front and end of this pattern?

 $text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]", 
                     "<a href=\"\\0\">\\0</a>", $text);  

Sorry for the dumb question.. I tried a couple things like

 $text = ereg_replace(" [[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/] ", 
                     "<a href=\"\\0\">\\0</a>", $text);  

 $text = ereg_replace("[ [:alpha:]]+://[^<>[:space:]]+[[:alnum:]/ ]", 
                     "<a href=\"\\0\">\\0</a>", $text);  

Neither seem to work but again I am not sure what I am doing... lol
