regular expression to underline a given word in a text...

[Fred]

Hi,

With the sentence :

"Bordeaux est au bord de l'eau"

How to do to underline, for instance, the word "eau" ? without underlining
the substring of "Bordeaux" ?
I don't know how to isolate the word...

My current code :

$text=eregi_rep lace("(".strips lashes($word_to _underline]).")","<b>\\0 </b>",$
text);

but this underline "eau" in "Bordeaux" too and i don't want to !

Thanks for any help !

Fred

Try:

preg_replace("/[^\w](eau)[^\w]/", "<u>\\1</u>", $text);
[color=blue]
> My current code :
> $text=eregi_rep lace("(".strips lashes($word_to _underline]).")","<b>\\0 </b>",$text);[/color]

Besides, use <u> for underlining text. <b> is for bold text.

Re,

Thanks !
it works perfectly !
Some improvement :

preg_replace("/([^\w])(".stripslashe s($tab_mots[$i]).")([^\w])/i",
"\\1<b>\\2</b>\\3", $texte);

(to correct a bug searching "l'eau" for instance)

Now, how to find the position of this word in a text ?
(not "eau" in "bordeaux" but the whole word "eau")

Regards,

$unbolded=strip slashes($text);
$bolded=preg_re place("/\b(eau)\b/", "<b>$1</b>", $unbolded);

Note that matching will be case-sensitive.

Look at strpos()

Note that doing so matches things like "eAu", "EaU", etc. but *only where
some character not in the set [a-zA-Z0-0_] occurs both before and after*.
If you also want to match against something like "Eau d'whatever", you need
a better regex. Check out the solution I already offered using word
borders \b. And if you want only the first letter to be case insensitive,
substitute "/\b([eE]au)\b/" instead.

Please do not multipost. If you feel the need for getting your post in
multiple newsgroups, crosspost (add additional newsgroup names to the
newsgroups: header in a comma-separated list). It saves the same solutions
being repeated over and over in different groups, thus wasting the time of
the people responding (as happened with the time I spent replying to you).
