Is PHP function names case-sensitive or not?

Solution
They are case insensitive, see this:
Note: Function names are case-insensitive, though it is usually good form to call functions as they appear in their declaration.

Problem
I am from Java background. In Java, every method has case-sensitive while calling. But in PHP, I didn't see the case-sensitive function name while calling the functions. ``` class Sample { ... ... function sampleFunction() { .... .... } } $obj = new Sample(); $obj->sampleFunction(); /* Proper call with function name */ $obj->samplefunction(); /* It should show undefined function error but it also calls sampleFunction() */ ``` Can anyone clear my doubt why this is also called even non-case sensitive function name. And please give me how to restrict in PHP? Thanks in advance.
