Bug description:php -m command gives unreadable output when run via exec()

Description:
------------
When I run the command "php -m" using:
- the exec function
- the shell_exec function
- a perl equivalent of the above

The output is unreadable like this:
OUT:Array ( [1] =>
�EQ�n�0��W���CED�RUȱ7���.����á�G^{f|�޻�]rWO������)ؤB���Z���%�����y���8�5J�f�#�ҬC�dd�o�`28�ǯ���/$��RƁC�����ĪZ�iŞI���띯5-Y�d\Q(
�t�ȏ�ݹ�a]M@�Z�m�{��\M=8�Q���5������V��
) 
RET:0

Other command such as "php --version" and executing the same on PHP
5.6.30 work fine.
The get_loaded_extensions function also works fine.
also tried running it with --no-php-ini but got the same result.

I can reproduce this on 2 servers with PHP 7.0.19.

Test script:
---------------
exec($bin.' --version', $extout, $extret);
echo '<br />OUT:';
print_r($extout);
echo '<br />RET:';
print_r($extret);
