-    PHP 7 adds support for return type declarations. Similarly to
-    <link linkend="functions.arguments.type-declaration">argument type declarations</link>,
-    return type declarations specify the type of the value that will be
-    returned from a function. The same
-    <link linkend="functions.arguments.type-declaration.types">types</link>
-    are available for return type declarations as are available for argument
-    type declarations.
+    PHP 7 增加了对返回值类型声明的支持。 就如
+    <link linkend="functions.arguments.type-declaration">类型声明</link>一样,
+    返回值类型声明将指定该函数返回值的类型。同样，返回值类型声明也与
+    <link linkend="functions.arguments.type-declaration.types">有效类型</link>
+    中可用的参数类型声明一致。

-    <link linkend="functions.arguments.type-declaration.strict">Strict typing</link>
-    also has an effect on return type declarations. In the default weak mode,
-    returned values will be coerced to the correct type if they are not
-    already of that type. In strong mode, the returned value must be of the
-    correct type, otherwise a <classname>TypeError</classname> will be thrown.
+    <link linkend="functions.arguments.type-declaration.strict">严格类型</link>
+    也会影响返回值类型声明。在默认的弱模式中，如果返回值与返回值的类型不一致，则会被强制转换为返回值声明的类型。在强模式中，返回值的类型必须正确，否则将会抛出一个<classname>TypeError</classname>异常.

-     When overriding a parent method, the child's method must match any return
-     type declaration on the parent. If the parent doesn't define a return
-     type, then the child method may do so.
+     当覆盖一个父类方法时，子类方法的返回值类型声明必须与父类一致。如果父类方法没有定义返回类型，那么子类方法可以定义任意的返回值类型声明。
