Strip letters in php

We have variable with text:

$text = 'I use something similar to pull the most recent pos开发者_如何转开发t from my blog and display a snapshot of it on my home page.';

How to strip first 40 symbols of this text? (including spaces).

Should work like this:

echo strip_text($text, 40);

Thanks.

With substr:

echo substr($text, 40);

Use PHP's substr:

$stripped = substr($text, 0, 40);
