question abour a simple regular expression...

[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 :

$text=eregi_replace("(".stripslashes($word_to_unde rline]).")","<b>\\0</b>",$
text);

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

Thanks for any help !

Fred

Assuming you mean 'au' instead of 'eau', you could use the following:

<?
$string = "Bordeaux est au bord de l'eau";

$string_u = preg_replace( "/(^| )(au)($| )/i", "$1<u>$2</u>$3",
$string);

echo $string_u;
?>
