php only return a part of a string for RSS description

[wendu]

hey

 

I'm trying to do RSS with PHP and currently it's working ok

 

how would I have PHP return only a part of a string that I can use in my RSS description? not just any given part, but words to a fixed point and then take one more word?

 

something line the first line of wordwrap(content, number)

use wordwrap, the explode by then new line delimiter and print the first result in the array

thank you

 

since I'm working with paragraphs I thouht I'd do it like this

 

explode("\n", content)

 

and then echo explode[0]

 

works pretty well, thanks

What you have right there may not always work out for you.  It's an rss feed so you never know what's going to come in.  There could be really long paragraphs or something and the \n might come too far down the string.  The best way to do it would be to first premove all \n's, then wordwrap, then explode at \n' and use the first exploded element.  Alternatively, wordwrap specifying a unique delimiter and explode at that.
