str_replace not working

I am stuck into a strange problem.
I am running php5 on apache.
and the problem is that str_replace command is not working

$name="mike stemle";
str_replace("mike","kite",$name);
echo $name.

Output should be 'kite stemle'
but strange, for me the output is still "mike stemle"

Am i making some mistake??

 

$name = str_replace("mike","kite",$name);

PHP:

str_replace() returns the new value and you have to assign it to a variable.

 

This will solve your problem:

$name="mike stemle";
$name=str_replace("mike","kite",$name);
echo $name.

 

oh my goodness!!

I am so stupid..
Thanks nico_swd and yiam. Green your way
Sorry nico system is not allowing me to give you green. As i gave u green 2-3 days before also. Anyway thanks man

 

Please write following code :

$name="mike stemle";
echo str_replace("mike","kite",$name);

 

i hate it when it is a really obvious fix.
ANd for some reason I can never see it

 

Hi, the funny thing is I did not make the above mistake and yet, str_replace is not working:

$pt_old = $this->text('title');
$pt_new=str_replace("a", " ", $pt_old);
