What is the difference between pass by value and pass by reference in javaThe difference between Java value transfer and reference transfer: 1. Transfer of basic data types; 2. Transfer of objects; 3. Modification of reference pointing. Detailed introduction: 1. Transfer of basic data types. For basic data types, Java uses value transfer. When a variable of a basic data type is passed as a parameter to a method, the value of the variable is actually transferred, not the value of the variable.

What does value passing mean in phpIn PHP, passing by value refers to copying the actual parameters when calling a function and then passing them to the formal parameters of the function. In fact, the formal parameters and actual parameters occupy different storage units. The characteristic of value transfer is one-way transfer, that is, when the calling function is called, a storage unit is allocated to the formal parameter, and the value of the actual parameter is passed to the formal parameter. After the call is completed, the storage unit of the formal parameter is released, and the value of the formal parameter is Any changes will not affect the value of the actual parameter, and the storage unit of the actual parameter still retains and maintains its value unchanged.
