That darn regex.

ThatDaniel

I hope this is right, I'm new here and have been needed help for awhile now. I'm not too advanced with REGEX in php, so I figured I'd have to ask some others about it.

So basically I have this string:

{ctml->url:profile/show?id=1}Dan</a> has visited {ctml->url:networks/show?type=region&network=126&networkname=st_louis}St. Louis, MO</a>.

My goal is to get the link from the {ctml->url:link} and run it through a custom PHP function "get_url();" and then return it as something like

'<a href="'.$get_url_response.'">Dan</a> has blah blah blah <a href="'.$get_response2.'">St. Louis</a>.

Of course that would be correctly formatted as it would outputted by PHP. The only problem is that I have no clue where to start, so any help would be much appreciated!

Thanks, Dan.

something like this might get you started.

 preg_replace( "#{ctml->url:([^}]*)}#" , "<a href='$1' >" , $s );

That a start, I could get almost that far (I really suck as Regex). I have another problem, as well though. I need to take that value and run it through a function called "get_url();", that way the link can be correctly formatted.

As far as I'm aware, I can't do something like like

preg_replace( "#{ctml->url:([^}]*)}#" , "<a href='".get_url(".$1.")."' >" , $s );

Can I? or is there a better approach to this?
(Thanks, by the way, I really appreciate this, I have no clue what I'm doing)

Something like this?

function get_url( $string ) {
    return  preg_replace( "#{ctml->url:([^}]*)}#" , "<a href='$1' >" , $string ); 
}

Not exactly. I need the value of $1 to be sent through the get_url function, not a function that that contains the string replacement.

Thanks. 🙂

You probably want to use preg_match_all.

 preg_match_all( "#{ctml->url:([^}]*)}#" , $s , $matches );

You can then loop thru the links and do a str_replace on the string.
$matches[0][0] will have the full string to replace and $matches[1][0] will have the bit to work on.
