php string replace not working

Question

I am running a code which takes a youtube url as input and i am using str_replace on it.

$title = str_replace('watch?v=', 'embed/', $title);

but the replacement just wont happen. I keep getting the same string back.

The youtube url im using as of now is http://www.youtube.com/watch?v=iwQx9gw2NfM

what mistake am I making ? The the serch string is CLEARLY present in the url but it wont get replaced.

Or is there a better way to do this ?

EDIT: The code works fine... I was trying to replace the wrong variable

Why do you hold the url in a variable called $title ? -- And otherwise, please show a bin2hex() output of its content. — mario

I copied your code exactly as it appears and the example URL you gave returns http://www.youtube.com/embed/iwQx9gw2NfM — Charles Sprayberry

are you sure you are not re-assigning the original value back to $title after the replacement has taken place? There is no reason the code you pasted should not work. Please add more of the surrounding code. — ghstcode

This code works fine:

$title = "http://www.youtube.com/watch?v=iwQx9gw2NfM";

$title = str_replace('watch?v=', 'embed/', $title);

echo $title;  //=> http://www.youtube.com/embed/iwQx9gw2NfM

You must have another mistake in your code. Please paste your context code for additional help.
