On the analysis of hook hooks in thinkphp

There is a hook class under the Library/think in the TP framework, which is used to instantiate classes and execute methods in the form of plug-ins.

static Private $tags = Array ();

Here is a static private member, here is the so-called hook function array, inside the specific content is an array

Array format: Arrays (' Method name ' =>array (class name, class name), ' method name ' =>array (class name))

Of course, in a single-instance design pattern, it is undoubtedly best to access these static members in a static way, so the get method of TP

It's a good illustration of the situation.

This is the first to determine whether the method tag is first created, if it is a static zone array with a key value is the tag value, value is an empty array, and then compatible with the 2 write mode, one is the name array is a string form, is not intended to construct the above I said

That plug-in array

What's strange about this is that his EXE method doesn't do any of the class existence and method existence judgment here, it feels weird.
