Hello.
Maybe this is the intended behavior, but wordwrap()'s behavior is a bit
illogical on PHP 4.3.1, as it does only break after a plain whitespace, not
after punctuation, \n, etc.
Here's a trivial sample :
$a = "wwwwwwwwwwwwwwwwww\nphprules\nwwwwwwwwwwwwwwwww";
print wordwrap($a, 10, ' ', 10);
Output :
wwwwwwwwww wwwwwwww
p hprules
ww wwwwwwwwww wwwww
The following trivial patch makes wordwrap() wrap after any
non-alphanumeric charater. Output after application of that patch :
wwwwwwwwww wwwwwwww phprules wwwwwwwwww wwwwwww
Best regards,
-Frank.
