Closing parenthesis of a multi-line function call must be on a line by itself

I am getting this message from phpcs. my code is:

$userdata["expirydate"] = date("Y-m-d H:i:s", mktime(date("H"), date(
        "i"), date("s"), date("m"), date("d") - 1, date("y")));

Your date("i") function call spans multiple lines. When this happens, that rule is enforcing that the closing parenthesis be on a line by itself.

If you want to adhere to that rule, you've got a a few options for reformatting your code.

You could use the PHPCS diff report to see how PHPCS wants you to format it. In this case, using --report=diff shows:

--- temp.php
+++ PHP_CodeSniffer

 <?php
 $userdata["expirydate"] = date("Y-m-d H:i:s", mktime(date("H"), date(
-    "i"), date("s"), date("m"), date("d") - 1, date("y")));
+    "i"
+), date("s"), date("m"), date("d") - 1, date("y")));

Which means PHPCS thinks the smallest change you could make would be to write your code like this:

$userdata["expirydate"] = date("Y-m-d H:i:s", mktime(date("H"), date(
    "i"
), date("s"), date("m"), date("d") - 1, date("y")));

Which is valid, but not great.

You could put it all on one long line, which is still valid:

$userdata["expirydate"] = date("Y-m-d H:i:s", mktime(date("H"), date("i"), date("s"), date("m"), date("d") - 1, date("y")));

You could split up the main date() call to make it valid and keep the line lengths shorter:

$userdata["expirydate"] = date(
    "Y-m-d H:i:s",
    mktime(date("H"), date("i"), date("s"), date("m"), date("d") - 1, date("y"))
);

Or you could even put every argument on a new line:

$userdata["expirydate"] = date(
    "Y-m-d H:i:s",
    mktime(
        date("H"),
        date("i"),
        date("s"),
        date("m"),
        date("d") - 1,
        date("y")
    )
);

It really depends on which code block you find more readable, and which code block fits best with your existing coding standard.
