PHP comparison operators have = = (equals) loose comparison, = = = (exactly equal to) strict comparison, where the face will introduce a lot of interesting questions. When loosely compared, PHP will unify their type, such as character to number, non-bool type to bool type, in order to avoid unexpected running effect,

There are two ways to compare JavaScript: the strict comparison operator and the conversion type comparison operator. For strict comparison operators (three =), the case for Ture is that only two operands have the same type, and for the widely used comparison operator (two =

Php's comparison operators include (equal to) loose comparison and (totally equal to) strict comparison, which introduces many interesting questions. This article will explain the security of php comparison operators for you, rela

An operator is a symbol that tells the compiler to perform a particular arithmetic or logical operation, and usually forms an expression along with the operand, which we often see as participating in mathematical operations or logical operations. PHP also contains a lot of operators, this article in detail to understand the important comparison operators.
