Re: [PHP] Re: split on whitespace, preserving whitespace...

2001-07-20 Thread Stefan Rusterholz 

If you'r using PHP 4 use preg_split. (works also with php 3 = 3.09)
see http://www.php.net/manual/en/function.preg-split.php for detailed
information.
The split pattern you'd need is:
$sometext2split = hello world  witha  lot   ofwhitespaces!;
$myarray = preg_split (/\s+/,$sometext2split);

you should get
$myarray := ['hello', 'world', 'with', 'a', 'lot', 'of', 'whitespaces!']

But remark: \t (tabs) will also count as whitespace, but not \n and \r. See
docu for more informations

Hope, it helps

 it does NOT however preserve the areas
 of white space.

 Instead the target of:
   $wordsarr = ('This','  ','contans','','white',' ','space','

 You get:
   $wordsarr = ('This','','contans','','white','space','','.')

 which has totally destroyed the whitespace I'm trying to
 keep intacted.

 I'm starting to wonder if maybe preg_match_all is better
 suited for something like this... just no idea how to do
 the regex that matches words  spaces and populates them
 into the array.

 maybe something like: echo
preg_match_all(|(\s+)?(.*)?(\s+)?|,$test,$arr);
 sigh... I dunno regex.

Re: [PHP] Re: split on whitespace, preserving whitespace...

2001-07-20 Thread Stefan Rusterholz 

Uuhmm, I'm sorry. I haven't read it throught to the end. The solution ist a
bit different:
use preg_replace to replace multiple spaces with single spaces:

$sometext2split = preg_replace(|,  ,$sometext2split); #make shure that
the separator isn't in the text anywhere around
$sometext2split = preg_replace(/\s+/, | |,$sometext2split);

and then explode the string (i don't know wether explode or preg_split is
faster, I tend to explode for simple split operations):
$myarray = explode(|,$sometext2split);

this should work. But probably it was a better solution to insert the spaces
with a loop between the words than to run the risk, that the separator is
somewhere in the text...

RE: [PHP] Re: split on whitespace, preserving whitespace...

2001-07-20 Thread Jack Dempsey 

Several of these solutions are good ideas, but they don't preserve the
whitespace as he desired. Preg_split with the capturing of the (\s+)
delimiter does the trick.

Nope that doesn't do it.
here's the test:
echo pre[$text]br[. implode('',$matches).]/pre;

here's the output:
[This  contanswhite space   .]
[Thiscontanswhitespace.]

If it were working the two lines should be identical.

That's not what I'm after though 
perhaps I should rephrase the question...

I want to do a split/explode on:
hello world  witha  lot   ofwhitespaces!
on spaces... in such a manner that when I join/implode 
it back together I get:
hello world  witha  lot   ofwhitespaces!
not:
hello world with a lot of whitespaces missing!

I'd be happy if I could even get:
$myarray = [hello , world  ,with,a  ,lot   ,
of,whitespaces!]

'cause I could spell check based on trimming the entry.

  sigh... I dunno regex.

The workstation I'm on is only running 4.0.4...
perhaps it's time to upgrade. :)

I'll try it again.

 Actually, it does. I just ran it again with that exact code. What
 version of php are you running? 
 Here's a direct copy/paste of what I get:
 
 code
 ?
 $text = This  contanswhite space   .;
 $matches = preg_split(/(\s+)/,$text,-1, PREG_SPLIT_DELIM_CAPTURE);  
 echo pre[$text]br[. implode('',$matches).]/pre;
 ?
 /code
 
 ouput
 pre[This  contanswhite space   .]br[This  contanswhite space
 .]/pre
 /output
 
 Are you running php = 4.0.5?

 Nope that doesn't do it.
 here's the test:
 echo pre[$text]br[. implode('',$matches).]/pre;
 
 here's the output:
 [This  contanswhite space   .]
 [Thiscontanswhitespace.]
 
 If it were working the two lines should be identical.

Re: [PHP] Re: split on whitespace, preserving whitespace... (a rephrase of the question)

2001-07-20 Thread Stefan Rusterholz 

I thought, Jack's solution should work (with php 4.05 and above), but
however if you say it doesn't then there is another solution. I don't find
it very hmm good, but it should work (I cannot test it, because a cant
rund php on this machine):

$text=your  space containing  text;
$splittext = new Array();
while ($text){
preg_match(/[^\s]+,$text);
if ($machtes[1]){$splittext[]=$matches[1];}
preg_replace(/$matches[1]/,,$text);

preg_match(/[\s]+,$text);
if ($machtes[1]){$splittext[]=$matches[1];}
preg_replace(/$matches[1]/,,$text);
}


If it doesn't work, I'm sorry, but currently I'm not able to test it. But I
hope, you can see the idea behind it.

best regards

  If you'r using PHP 4 use preg_split. (works also with php 3 = 3.09)
  see http://www.php.net/manual/en/function.preg-split.php for detailed
  information.
  The split pattern you'd need is:
  $sometext2split = hello world  witha  lot   ofwhitespaces!;
  $myarray = preg_split (/\s+/,$sometext2split);
 
  you should get
  $myarray := ['hello', 'world', 'with', 'a', 'lot', 'of', 'whitespaces!']

 That's not what I'm after though
 perhaps I should rephrase the question...

 I want to do a split/explode on:
 hello world  witha  lot   ofwhitespaces!
 on spaces... in such a manner that when I join/implode
 it back together I get:
 hello world  witha  lot   ofwhitespaces!
 not:
 hello world with a lot of whitespaces missing!

 I'd be happy if I could even get:
 $myarray = [hello , world  ,with,a  ,lot   ,
 of,whitespaces!]

 'cause I could spell check based on trimming the entry.

  But remark: \t (tabs) will also count as whitespace, but not \n and
  \r. See
  docu for more informations
 
  Hope, it helps

Maybe you've already tried this and rejected this for some reason, but my 
inclination would be to split on \b (the non-character boundary between a 
\s+ next to a \w+).
