Replacing strings of text?

[Mutley]

I have an IPB forum, which when someone creates a smilie, it outputs this as the img src:

 

"style_emoticons/<#EMO_DIR#>/wink.gif"

 

The IPB software looks for this directory in the config but I'm writing a script to use it on a webpage. How can I make it so when I call this from the database in a script I am writing, it replaces <#EMO_DIR#> with something like 'smilies', so the image is then displayed correctly?

 

Another example is when a user quotes someone.

 

<!--quoteo(post=359329:date=Mar 26 2008, 05&#58;52 PM:name=Mutley)-->

 

How would I replace it with something simple like:

 

<table class="quote">

 

I hope that makes sense, basically I want to replace certain strings from my database.

For the first one you'd use str_replace:

 

$string = "style_emoticons/<#EMO_DIR#>/wink.gif";
$string = str_replace('<#EMO_DIR#>', 'smilies', $string);

 

And for the quote one you'd use preg_replace:

 

$string = "<!--quoteo(post=359329:date=Mar 26 2008, 05:52 PM:name=Mutley)-->";
$string = preg_replace('/\<\!\-\-quoteo\(post\=([0-9]+)\:date\=([a-zA-Z0-9 ]+)\, ([0-9]+)\&\#58\;([0-9A-Z ]+)\:name\=(.+)\)\-\-\>/', '<table class="quote">');

 

I'm pretty sure that'll work. You can also display the post id, date, and username of the quote using preg_replace if you want.
