How to remove domain duplication from php parser?

Question

PHP

site.com - Simple Domain
Stand I have a problem in the parser, I start parsing, it gives the following: Error: Unable to load page: https://www.site.comhttps://www.site.com/page/dog-...
As I understand it, it substitutes the domain for the link how to remove this error?
