Description:
------------
Calling ereg_replace before pspell_new crashes pspell.

pspell_new *only* fails when calling ereg_replace before it (i.e. I haven't witnessed any other crashes yet...)

Pspell is installed following this guide (and all is working):
http://www.oblius.com/?.blogs.184

Changes in php.ini file:
extension=php_pspell.dll

Reproduce code:
---------------
<?
  $string1 = "heeelp";
  $string2 = ereg_replace("squeek","squaak",$string1);
  $pspell_link = pspell_new("en", "", "", "", PSPELL_FAST);
  print_r(pspell_suggest($$pspell_link, $string1)
?>

Expected result:
----------------
when I comment this line:
// $string2 = ereg_replace("squeek","squaak",$string1);

the result is:

Array
(
    [0] => help
    [1] => Heep
    [2] => heel
    [3] => heeler
    [4] => heeled
    [5] => heels
    [6] => whelp
    [7] => helps
    [8] => helper
    [9] => harelip
    [10] => hep
    [11] => Helen
    [12] => hello
    [13] => heel's
)

Actual result:
--------------
Warning:  pspell_new() [function.pspell-new]: PSPELL couldn't open the dictionary. reason: No word lists can be found for the language "en".  in c:\Apache\htdocs\Work\bug.php on line 5


Warning:  pspell_suggest() [function.pspell-suggest]: 0 is not a PSPELL result index in c:\Apache\htdocs\Work\bug.php on line 6

Pay attention to double "$" here:
print_r(pspell_suggest($$pspell_link, $string1));
And try again.

Hi tony,

no idea how those two syntax errors got there, however, the bug is still there:

This works (same output as before):

<pre>
<?
  $pspell_link = pspell_new("en");
	
  $string = ereg_replace("squeek","squaak","squobble");
		
  $pspell_result = pspell_suggest($pspell_link, "help");
		
  print_r($pspell_result);
?>
</pre>

This doesn't:

<pre>
<?
  $string = ereg_replace("squeek","squaak","squobble");
	
  $pspell_link = pspell_new("en");
		
  $pspell_result = pspell_suggest($pspell_link, "help");
		
  print_r($pspell_result);
?>
</pre>

For the most basic version:

  $string = ereg_replace("squeek","squaak","squobble");
  $pspell_link = pspell_new("en");

DOESN'T work, while

  $pspell_link = pspell_new("en");
  $string = ereg_replace("squeek","squaak","squobble");

DOES work.

For the exact error messages, see my first post.

I tried exactly the same on another installation of PHP/pspell (5.0.3 as well) I have on a different computer and there it DOESN'T crash. If there are any additional tests I can run, let me know.
