[php-src] Issue #8005: in_array string checking error......

Issue: https://github.com/php/php-src/issues/8005 Comment Author: damianwadley The function is behaving exactly as intended, as designed, and as documented: by default it performs loose comparisons against array items, and thus it would return true for your inputs because "any content" is loosely equal to 0. If you want strict comparisons instead of loose comparisons then you must provide the third argument.
