If so, how does PHP's memory management work in the case of gc_disable?

循环引用计数The collector is just one of the GC's and is only introduced after the 5.3 version.

In the 5.2 and earlier versions, there is not no GC, but only based on 引用计数 the base GC, note the difference between the two nouns

The circular reference count collector can affect the efficiency of script execution when the object or array is many, so it is possible to invoke force shutdown to improve performance when you are sure that your script will not be produced, 循环引用 gc_disable but it does not mean that the entire garbage collection mechanism is closed
