mb_eregi_replace

[=?iso-8859-1?B?RnJhbiBHYXJj7WE=?=]

I think that there is a problem using the mb_eregi_replace function.
I've noticed that it doesn't work well when it must replace "À bon
chat" for "<b>À bon chat</b>" using the next call:

mb_eregi_replace("à bon chat","<b>\\0</b>",$mystring);

Have anybody noticed that? How could I solve it?

Thanks in advance!

I got this malfunction using PHP Version 5.1.2, but if I use PHP
5.2.0, it works well. Always on Windows Plattform using xampp.

I've a possible solution. You can use some javascript code to replace
all the occurrences with something like this:

myRe2 = new RegExp('à bon chat', 'gi');
document.getElementById('only_context').innerHTML = new
String(document.getElementById('only_context').inn erHTML).replace(myRe2
,'<b>$&</b>');

You must include the text, that you wanna replace into a div called
'only_context' or whatever.

mb_eregi_replace works well on PHP 5.2.0
