First look at a special case: Var_dump (0 = = ' false '), returns BOOL (true), PHP determines 0 equals any string, Var_dump (0=== ' false '), returns BOOL (false), and the congruent contains type and value to be equal. Var_dump (0 = false), returning bool (true), Reasons for the above results (translated from the official PHP document): 1. For bool: When you output a bool or use it in a statement , it is converted to a number, true to 1 , and fa

The XML document contains text similar to "Elements looks like 1.CDATA Zone: It's all called character data, to ""begins with the" ]]>"End, embedding the original data between the two that does not want to be parsed by the parser, and the parser does not parse the content in the CDATA area, but Leave this data intact to the downstream process. 2.

We can see three equal signs that have never been written before, maybe it's because my JS technology is still in its infancy, I checked some materials on the Internet and said that this is a fully equal sign. I used to use the equal sign "=" and never used the fully

1. Two lists if there are duplicate elements (such as List1:a,b,a list2:b,b,a), it is not possible to determine equality by including a relationship.There are two options, one of which is to sort the two lists and then compare them sequentially. The other option is to calculate the duplicates of each element before comparing them.The first option is too obvious and time is too bigThe second is space-time, and only needs to be traversed without ordering. /// ///Determines whether t
