Replace characters in a string?
<p>I Want to change some of the character in a string.
Lets say the string is like this: "hello my name is santa" and i want to change all the a's in the string. I Think i need a foreach but unsure how to use, and unsure how im going to replace since erex_replace is depreaced in php5.</p>

<p>any help would be awesome.
