Dreamweaver lying about a syntax error


Question

Hi all,

I just wondered if someone knows how to disable a specific syntax error from appearing in Dreamweaver CS5.5, or otherwise how to 'upgrade' Dreamweaver's PHP syntax checker. My problem is:

  Quote
http://php.net/manua....comparison.php

The expression (expr1) ? (expr2) : (expr3) evaluates to expr2 if expr1 evaluates to TRUE, and expr3 if expr1 evaluates to FALSE.

Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression expr1 ?: expr3 returns expr1 if expr1 evaluates to TRUE, and expr3 otherwise.

Thanks for any help :)

Not too sure what you mean when you say 'cast to boolean', but thanks for the 2nd tip. Changed lines 16 & 17:

$admin = ($_SESSION['status'] == 3 ? true : false);
$loggedin = (count($_SESSION) ? true : false);

$admin = ($_SESSION['status'] == 3);
$loggedin = (count($_SESSION));

Never thought of doing that before, so cheers! :)

You're using PHP 5.3 specific code, does Dreamweaver (or your version of) support this?

Evidently not, hence why I need to upgrade it to :p

Edit: Sorry, I should've said which version of Dreamweaver I'm using in the OP, but it's CS5.5. Edited to reflect.

I think you'll have to use the dynamic code hinting feature in dreamweaver to get it to attempt to support 5.3 but to be honest when i started with PHP i soon wrote off Dreamweaver as an IDE and php support is very limited. I personally use Netbeans now, it is free and has much better support for PHP and has a tonne of features.

To be honest with you, I used to whole-heartedly agree about DW being a horrible IDE for writing PHP, but it seems to have come a long way since the Adobe buyout, and I'm actually very impressed with CS5.5

Code hinting however is not the solution... all code hinting is, is this:

Edit: Actually it looks like CS5.5 adds support for PHP 5.3 for code hinting at least, so I don't know why not for syntax checking: click. Putting expr2 in the middle of the ternary makes the syntax error go away, but I don't wanna have to write "old-code".

@giantpotato, I see what you're trying to say, but the boolean is expr1, thus my code of:

$uid = ($_SESSION['uid'] ?: false);

is correct.

@Anthony, I just took a look at the new features of PHP 5.3, and tried out Nowdoc - it validates syntactically correct:

$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
EOD;

Seems like it's a DW bug :(

Just noticed jump label support was added into PHP 5.3 ( :|), and that also validates correctly:

goto a;

Also just tried a namespace, and that validates correctly too:

namespace foo;
  class Cat { 
    static function says() {echo 'meoow';}  }

So I guess it must be a bug!

Both come back as invalid... with and without trailing semicolon.

Also, seems like Bugbase is only for AIR & Flash bugs, so reporting here instead.

Edit: Reported! Guess there's nothing more I can do, so I'll just have to put up with a ton of red markers all over my code :p

    • I mean at this point, why even have a desktop? Just open a browser window full screen and send her to her homepage. Access to anything she needs right there. Could be on Linux, could be on Android, heck could also be on Windows 11. No one would know!
    • Will be replacing my last 2 Windows 10 PC's in household ASAP, if they could upgrade now i've done it already. Main Desktop runs Windows 11 already, that ones all set. Now just to get the other 2 all set asap
    • I think you answered why it gets so much attention in your comment. It's designed to make Windows accessible to everyone! It's a core component of the Windows UI, and 30 years of its existence is why it remains such a key component and receives so much attention to this day!
    • I agree with your points, particularly around workflows. But I think this is a symptom of the way Microsoft plans, builds, and releases its OS's, not about its UI ideals itself. It has historically been large jumps in UI changes between releases, XP > Vista > 7 > 8 were ALL significant changes in how we performed tasks. Then Win10 was released and updated twice a year with minor changes. This was somewhat nice as the changes were often minimal, however as it looked like the same OS for the most part, when something did change (like the start menu), it was a bit confusing for people who didn't understand that they had actually been upgraded, and why just this one key part of their workflow had changed. But I believe that was too slow, and didn't allow their future designs to be played out in that release structure. So the "last Windows version ever" was superseded with a new UI and overhauled once more. It too has changed quite a bit in its 4 years, but I think there needs to be an understanding of that change, which I guess we have in the "24H2" version numbering, but not in the marketing that most users know. The most consistent and clear communication of changes I think is done with MacOS. While I'm not a fan of Apples software, their clear and consistent release schedule, and progressively planned changes to the OS is easy to understand, leading towards a well thought out goal. Their users understand the branding of the big updates, and that changes will occur when they update, yet these are more subtle than changes we see in Windows 7 > 8 > 10 > 11 releases. On that, Windows 10/11 version updates just get lost in the vast collection of update types in Windows Update, and as such most users wouldn't know if the were on 22H2, 23H2 or 24H2, or even know what those meant. My thoughts are that Microsoft will drop the Win11/Win12 branding once Windows 10 has finally died. And hopefully, make it a bit more consistent with feature/UI updates sticking to an improved branded version/year release rather than "moments" or just randomly enabled elements in a random monthly update. Until then, even us tech users rarely know what features are in what release and if we will see it on our own computers. Get with it MS!
