Can PHP namespaces contain variables? If so, how can this be accomplished?
385
A namespace can contain valid PHP code. Namespace affects following types of code: classes (including abstracts and traits), interfaces, functions, and constants.
A namespace is a declarative region that provides a scope to the identifiers (the names of types, functions, variables, etc) inside it. Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially when your code base includes multiple libraries.
Namespaces are qualifiers that solve two different problems: They allow for better organization by grouping classes that work together to perform a task. They allow the same name to be used for more than one class.
A namespace is a way of grouping identifiers so that they don't clash. Using a class implies that you can create an instance of that class, not true with namespaces. 2. You can use using-declarations with namespaces, and that's not possible with classes unless you derive from them.
No. You can set a variable after declaring a namespace, but variables will always exist in the global scope. They are never bound to namespaces. You can deduce that from the absence of any name resolution descriptions in
There would also be no allowed syntax to locate variables in a namespace.
print \namespace\$var; // syntax error print "${namespace\\var}"; // "unexpected T_NS_SEPARATOR" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
