Hello Mr. Gilmore—

there’s a minor bug on pg. 2 of the refcard. The equality operator does not belong into the function declaration, there has to be an assignment operator.

// Wrong:
function __construct($id=="") {

// Correct:
function __construct($id="") {

Kind regards,
Willy Dee.

Hello Willy Dee,

Thanks for taking the time to download, review, and provide feedback on the PHP refcard. I've passed along your feedback to the author, and we are working to correct the error. A new version of the PHP refcard will be available within the next couple of days.

With Kind Regards,

Jill

We've had some feedback on the PHP refcard from the community, and have updated it to reflect a few edits to fix some errors. The new version is now available. Go here and click on "Click Here to Download PDF" to download the new version.

What's changed:

Page 2, Column 1 - Under the section "Class Constructors", the first line has been changed to read:

function __construct($id="") {

In addition, there was a formatting issue regarding the double underscores in the same section, and the section that follows it. They have been changed to reflect one contiguous long underscore.

Page 3, Column 1, 1st Table - Under the "Creating an Array" section, the following was deleted:

$stations << "WTVN";
$stations << "WBNS";
$stations << "WYTS";

It is not valid PHP.

Thanks to those who have provided feedback.

-- Jill

Hi Folks,

Well, it seems we missed an edit in that table on page 3. A new version of the PHP refcard is available. Go here and click on "Click Here to Download PDF" to download the new version. My apologies for the mistakes. This version is correct.

phpunit has been hosted on phpunit.de instead of pear.php.net since around 2006-06-29. The last version released on pear.php.net was version 2.3.6! (Version 3.3.1 is the most current). Could you please revise your PDF to correct this? Pointing people to a very old version of PHPUNit would only serve to confuse them! Thank you.

Thanks for the feedback. We will make the correction, and update the PDF as soon as possible. I'll post a note here when it has been updated.

Thanks again,
