Hi there..

I got a part of my website where I want to display a preview of a long story.

For example the first 40 words should be there, but a sentence should not be "broken"
So the maximum should be 40 words.

I can substr() to a number of characters.. but how to manage my problem as told above?

explode() the string on all white spaces.
array_splice() it to get the first 40 words.
implode() the space again.

thnx!..

Got it fixed with the split at the last "." in the text:

PHP Code:

$item_rechterkant_verhaal = explode(' ', $item_rechterkant_verhaal); 
array_splice($item_rechterkant_verhaal, 40); 
$item_rechterkant_verhaal = implode(' ', $item_rechterkant_verhaal);

$item_rechterkant_verhaal = explode('.', $item_rechterkant_verhaal);
$aantal = count($item_rechterkant_verhaal)-1;
array_splice($item_rechterkant_verhaal, $aantal);
$item_rechterkant_verhaal = implode(' ', $item_rechterkant_verhaal).".";

I got this fixed with a "." as separator.
But there is a problem if a sentence end with a "!" or a "?"
How can I build in this multiple separator?.

Use preg_split() instead.

PHP: preg_split - Manual

okay...

so it should become something like this:

PHP Code:

$news = preg_split("\.|\?|\!", $news);                                    
$aantal = count($news)-1;
array_splice($news, $aantal);
$news = implode('.', $news)."."; 

to split on the sentence ending on: . - ! - ?

Unlike the ereg_* functions, the preg_* ones work with delimiters (the expressions begin, and end with the same character). See the examples on the page I posted.

cool! fixed it.. thnx nico!

PHP Code:

$news_1 = preg_split("/\.|\?|\!/", $news, -1, PREG_SPLIT_OFFSET_CAPTURE);
                                    
$news_intro = $news_1[0][0];                                
$from = ($news_1[1][1])-1;                                
                                    
$news_intro_end = substr($news, $from, 1) ;

Nice one!

EDIT: Sorry. to fast. it's an array so for sure I can count it!

can I count the numbers of "founds" in this preg_split..?
