On Windows, a file is considered executable, if it is a properly executable
file as reported by the Win API <literal>GetBinaryType()</literal>; for BC
reasons, files with a <filename>.bat</filename> or <filename>.cmd</filename>
extension are also considered executable. Prior to PHP 7.4.0, any non-empty
file with a <filename>.exe</filename> or <filename>.com</filename> extension
was considered executable. Note that <envar>PATHEXT</envar> is irrelevant
for <function>is_executable</function>.
