PHP7 deprecated features
Core:
- PHP4 style constructors will be deprecated. (Methods with the same name as the class name are considered constructors, which is the syntax of PHP4.)
- Static calls to non-static methods will be deprecated.
OpenSSL
The capture_session_meta option will be deprecated and can be obtained by calling stream_get_meta_data().
PHP4 style constructor
In PHP4, the function in the class can have the same name as the class name. This feature is available in PHP7 is discarded, and an E_DEPRECATED will be issued. mistake. When the method name is the same as the class name, and the class is not in the namespace, and the PHP5 constructor (__construct) does not exist, an E_DEPRECATED will be generated. mistake.
Example
<?php
class A {
function A() {
print('Style Constructor');
}
}
?>The above program execution output result is:
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; A has a deprecated constructor in...

Calling non-static methods in a static way is no longer supported:Instance
<?php
class A {
function b() {
print('Non-static call');
}
}
A::b();
?>The above program execution output result is: Deprecated: Non-static method A::b() should not be called statically in...Non-static call
