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.

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'm just commenting because of this madness. you simply asked "what crowd" which i too am genuinely curious about, only to receive a response in the form of a link that directs to an analysis of the audited financial statements with the accompanying notes. then you say that the guy who wrote it is stupid, which whatever, that's not an argument being discussed atm, only to receive a response from Arceles saying "i don't deal with people whose first response is an ad homenim". jesus. this is like making a claim, and then saying "i don't deal with people who speak in a certain way or swear so i'm not gonna answer you hah!" (said in a nasaly voice, not trying to depict you Arceles). then focus on the argument instead of the explanation begins... "so what don't you like about the guy (lunduke)" followed by "he just likes to insult people" and the explanation for the "crowd" being referred to was never even established. so a request for an explanation about the crowd turned into an argument about "why do you think lunduke is an idiot". wowza.
    • Sony lays off 30% of staff from Days Gone developer Bend Studio by Pulasthi Ariyasinghe Another wave of layoffs has hit the game developer space, and this time, it's a first-party Sony studio that's been affected. Following a report by Bloomberg's Jason Schreier, Bend Studio has confirmed that it is letting go of "incredibly talented teammates" as it begins work on a new game project. "Today, we said goodbye to some incredibly talented teammates as we transition to our next project," said Bend Studio in a social media post today. "We're deeply thankful for their contributions as they've shaped who we are, and their impact will always be part of our story." Bend Studio is most well-known for its 2019-released open-world zombie adventure Days Gone, which even received a remaster just a few months ago. Prior to that, the studio had been responsible for the classic Syphon Filter series while also developing several PlayStation Portable and Vita games like Resistance: Retribution and Uncharted: Golden Abyss, respectively. "This is a difficult moment for our team, but we hold immense respect for everyone who got us here," the company added. "As we move forward, we remain committed to building the future of Bend Studio with creativity, passion, and innovation in the titles we craft." While Sony did not detail just how many staff have been affected by this latest decision, Jason Schreier revealed that 30% of the studio is being laid off. This amounts to around 40 people, according to the reporter. Earlier this year, Sony canceled two live service games that were in development at Bend Studio and Bluepoint Games. It was never revealed what this mystery game was supposed to be. "Bend and Bluepoint are highly accomplished teams who are valued members of the PlayStation Studios family," Sony said at the time. It's unclear if Bluepoint, which had been developing a God of War live service experience, will soon be hit by its own wave of layoffs too.

    • I had this issue and it is a nova android conflict issue. Initially the only way to fix it was clicking the screen off and then back on. Figured out it was because of a task I set up in tasker to load certain apps when I connect to my car, so fixed it by adding a 'go home' task after the app loaded and rarely have the issue now
    • I wish one of the windows updates hadn't broken glass. Is there a workaround for that I'm not aware of?
