any ways to get the first 50 words??

hi guys
i want to extract the first 50 word from a text.. is there any php function which will let me do that??
thanks in advance..

 

I think this regex will do the trick

  $numwords = 50;
  preg_match("/(\S+\s+){0,$numwords}/", $long_string, $regs);
  $short_string = trim($regs[0]);

PHP:

 

Try this:

preg_match('#((?:\S+\s+){50})#', $string, $matches);
echo $matches[1];

PHP:

This is similar to the above but the actual index in the array is 1 not 0. Also you the above regex will match the first word only...

 

Why do we need regex, won't

$text = substr($text, 0, 50);

PHP:

Do the trick?? Where $text is the text you want to trim to 50 characters. You can save it in a new variable, that one just overwrites $text.

 

That would work if you want to get the first 50 Characters but he was asking for the first 50 words. In which case it's best to use a regex that counts the first 50 words. See http://www.the-art-of-web.com/php/truncate/ for more methods of truncating text.

 

ooooooops I see I see

 

dude. read the question properly.. i said 50 words not characters..
but thanks anyways..

 

Yeah I said oops I had realised the mistake already, so why point it out again?
Thanks anyways...

 

can anyone explain the patter part of the preg_match??
