Looking for a PHP function

[Guest Feces lover]

Is there any PHP function that can output a string at a given position of another string? I've looked through the PHP Manual and couldn't find it.

Can you give an example?

Orio.

Try using, substr(), spliting off the first part of the string, inserting your part, and then adding on the end, also found with substr().

OK, here's an example. I'm making a PHP chatbot

if (stristr($input, 'my') !== FALSE && stristr($input, 'name') !== FALSE){
$name = //function that gets the 4th word of $input goes here
$response = ("Hello $name!");

And I'll try the substr() suggestion.

I figured out a simple way to do it, which makes me feel really stupid:
[code]
if (stristr($input, 'my') !== FALSE && stristr($input, 'name') !== FALSE){
$name = substr($input, 10);
$name = trim ($name, '.');
$response = ("Hello $name!");
}
