String Manipulation

[b00ker_b0y]

hey people;

 

got my self in a bit of a problem.

 

I read from the database a piece of text i.e.

 

"Hello one, two, three.<br><br>Click <a href='index.html'>here</a> now. Sentence 3. Setence 4."

 

I use the the following code to basicly only take the first 3 sentences:

 

    $str_arr = explode(".",$data[Content]);

        $summary = $str_arr[0].".".$str_arr[1].".".$str_arr[2];

 

so i basicly just uses the full stops as like a end of line marker, but in the second sentence as part of the hyperlink there is a full stop which is being read as one, then messing up my output.

 

Is there anyway i can ignore this full stop? or is there a way is can remove the link wothout removing the hyperlink text from the string?

 

Help would be appriated! thanks.

you would need preg_split();

 

the regex would have to search for '.' that are not inside an a tag (you maybe want to control whether its in other tags too!!)

 

$str_arr = preg_split('/(?!<a(.)*?>)(.)*?\.(.)*?(?!<\/a/)',$str);

 

something like that (don't expect that to work straight off but someone much better at regex will correct me! )
