  • Introduction to Objects and References in PHP Memory (Publication)
    https://www.toptal.com/php/objects-references-php-memory
    In this article, I will talk about how object and variable references are controlled in memory, since this is an issue that can generate discussion and differing opinions. One question to ponder is: "By default, are objects passed by reference or by copy in PHP?" I'm going to talk first about what references aren't in PHP; second, I'll discuss what they are, and finally, I will examine how the garbage collector works in PHP.
