CAUTION: This function will NOT do what you expect in many cases when you use arrays as both search
and replace parameters. I found this out the hard way in a production website...
Consider the following code:
$a = "abcd";
$a = str_replace(array("a", "b", "c", "d"),
array("albert ", "belinda ", "charlie ", "diana "), $a);
echo $a;
You would expect it to output "albert belinda charlie diana ", but it outputs:
"albelindiana a ert belindiana a charlie diana "
str_replace() simply executes itself for each array element, using the *already modified* string as
input. This should be clearly noted in the manual.
