You changed the string to be "abcd\0f" on line 8. You didn't remove the
character, you set it to nothing.
If you want to remove the character instead... you have to slide
everything after it in the string back a place.
There are lots of ways to do this. For example,
$var = join("", split("e", $var));
will remove all instances of "e" from $var (I find this is the most
common manipulation of this type I want to do).
Joining together two string parts will also work.
$var = substr($var, 0, 4) . substr($var, 5, strlen($var));
ereg_replace() also springs to mind.
