Is there any literature on the Internet about OOP PHP?

Question

PHP

I took courses in PHP programming at the training center, but still it
didn’t work out to program and understand from A, (at least) to F. The video tutorials gave me basic knowledge,
the training center gave me the basic knowledge of OOP PHP, but
I didn't succeed in creating, solving and understanding PHP itself. Many people advise reading literature, but not
in Russian (I won’t even find out why), and after all this, I had a question:
- Are there books in English on the Internet that will really make you understand the basic concept of PHP OOP, or at least OOP itself and PHP separately?
If there is, who can share a link to these books? Or post it online?
I thank in advance all those who were not too lazy to read everything to the end, understood my problem and helped in solving it.
