preg_replace

[Anon]

I'd like to replace only "a" to "*". and "aa", "abc" etc are not to be replaced.

How do I do that with preg_replace.

<?

$intext="Have a good day";
$patterns = array('/^a$/');
$replace = array ("*");
$intext=preg_replace($patterns, $replace, $intext);
echo $intext."<P>";

?>

It should show "Have good day". but it always show me "Hve good dy".

Any idea?

$text = "Have a good day";

$replace = eregi_replace("a", "", $text);

echo "$text";

Try this (I didn't):

$text = "Have a good day";

$replace = preg_replace("/\ba\b/", "*", $text);

echo "$text";
