PHP supports inheritance since PHP 3. Neither PHP, nor Java, nor C# support multiple inheritance. PHP 5 supports interfaces like Java and C#. That addresses most purposes developers would want to use multiple inheritance.
C++ supports multiple inheritance but it is confusing and often you need to solve conflicts to sort from which class functions or variables are inherited.
