Bug description:in_array confusing strings and integers

Description:
------------
using PHP Version 5.6.14-0+deb8u1 on a debian operating system, here is
what I get with the following testing script.
I think that 'Expected result' should be obtained without using the
third parameter of in_array ([, bool $strict = FALSE ]) otherwise it is
very confusing.

Test script:
---------------
echo 'test1:'.(in_array('string',[0,1])?'true':'false');
echo 'test2:'.(in_array('string',[1])?'true':'false');
echo 'test3:'.(in_array('string',[0])?'true':'false');

Expected result:
----------------
test1:false
test2:false
test3:false

Actual result:
--------------
test1:true
test2:false
test3:true
