Trying try/catch for the first time – php

I have done a lot of PHP coding but never used try/catch before. First time user. It won’t work, does not even compile. I am trying this very simple example.

$x = 0;
try {
    if ($x == 0) {
        throw new Exception('x is zero');
    }
} catch (Exception $ex) {
    echo 'Caught exception: ', $ex->getMessage();
}
echo 'after try block';

When I run this, I get this error message referring to the line with the catch in it.

Parse error: syntax error, unexpected '$ex' (T_VARIABLE), expecting ',' or ')'

Was expecting to get the Caught exception line displayed.

    echo 'Caught exception: ', $ex->getMessage();

    instead of comma, there should be a full stop for string concatenation

    echo 'Caught exception: '. $ex->getMessage();

    I think you copied this from the PHP manual. The manual doesn’t use real spaces in their code. That has tricked me up several times already. See:

    Here the fake spaces are shown:

    You need to make sure you’re using real spaces.

    In some editors you can make these fake spaces visible, and some other editors will already replace them for you.
