Basic php string operations

Question

Example
<?php
$url = '
http://username:password@hostname/path?arg=value#anchor';
print_r(parse_url($url));
echo parse_url($url, PHP_URL_PATH);
?>
output:
Array
[scheme] => http
[host] => hostname
[user] => username
[pass] => password
[path] => /path
[query] => arg=value
[fragment] => anchor
/path
Question:
For example, I want to do something with the host, like run
some string replace operations on it, but how do I access
it?

You should read about how to use variables and arrays or use
the second
parameter of parse_url() to only return the host name as a
string like
you did in the second example (see the manual for details).
Then assign
the return value to a variable and you can do whatever you
want with it.
