Changing macOS Sierra prevents "say" to be exec'd in a PHP script

Question

I have a MacOS server with a small site that converts text fragments to audio using the command say.

Everything went smoothly with the upgrade to Sierra, except for one thing: the command sayno longer works when it is included exec()in my PHP script.

The page just stops working. No error detected.

<?php
    try {
        exec('/usr/bin/say "hello"');
    }
    catch (Exception $e) { echo $e->getMessage(); }
?>

I usually saved audio fragments say -o filenamewith, say -o filenamebut I tried all the options, as well as other shell commands that worked fine, including creating files in my output folder.

Interestingly, if I run it from the command line, it works - it either speaks loudly or creates an output file.

say Jenkins. Jenkins macOS Sierra.

:

• jenkins ssh ssh-keygen.

• ~/.ssh/id_rsa.pub .ssh/authorized-keys, .

  cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized-keys
  

• Jenkins, say :

  ssh localhost say -v Alex "Test"
  

, Apache/PHP, :

<?php
    try {
        exec('/usr/bin/ssh localhost /usr/bin/say "hello"');
    }
    catch (Exception $e) { echo $e->getMessage(); }
?>
