ID: 49980 Comment by: ronlentjes at yahoo dot com dot au Reported By: ronlentjes at yahoo dot com dot au Status: Open Bug Type: Scripting Engine problem Operating System: Fedora 11 PHP Version: 5.3.0 New Comment:
I did this from command line to be very simple to test: (I kept the \n away from example in separate echo just for clarity): <? $s = 'xxx'; echo "{$s}"; echo "\n"; echo "\{$s\}"; echo "\n"; echo "{\$s}"; echo "\n"; echo '(' . "$s" . '}'; echo "\n"; ?> Sorry, I did type this from other computer screen so typo possible. The results for new versions: xxx \{xxx\} {$s} {xxx} You see the misinterpretation of old user's case is that you thought they wanted {$s} to be printed by saying use \$. That is not what customers want. They want this result: {xxx} But now that you disabled \{ escaping, you must now put { into a variable or '{' string constant and change all code to concatenated with that string. As shown above with this piece of code: echo '(' . "$s" . '}'; echo "\n"; That is really ugly. You used to be able to do this: echo "\{$s}"; echo "\n"; That is the WHOLE point.

That was a bit annoying. Please have this reviewed with others before just closing it like that. This is NOT an old issue as this is a new suggestion for a way forward as customers are complaining! Slamming to door on them will only infuriate them! Escaping curly braces produces backslash in output. Bug #37263 Escaping curly braces produces backslash in output.

Bug #37263 Escaping curly braces produces backslash in output. STATUS: Should not be bogus. It is a real issue not understood by PHP staff. I do have a simple solution to this. Read on... I noticed this bug come up in app. I think you have misunderstood how bad this is and I consider this to be a bug as well. I understand you made a change so that \ infront of any character not on the list of escapes will print \ with that offending character. This is good. All you have to do now is add { as an escape to the list so that \{ produces a single { that will solve all the problems. The original person who created this bug was trying to explain to you that you gave no reasonable way ahead to fix old code and I think there was miscommunication. I too see this as a bug. What you missed in adding the VERY GOOD idea of printing bad escapes, is the \{ has been a VALID ESCAPE in previous versions. To fix this simply add { to your list of valid escapes and produce a single { when encountered. That will keep every one happy. N.B. I now have to go through 1000's of lines of code and fix up every occurance of this \{ which was realied apon as a very acceptable ESCAPE sequence. (BUT NOW HAVE TO KEEP 2 VERSIONS!!) Cheers, Ron Lentjes LC CLS. Reproduce code: --------------- When $ is involved: { -> nothing (0 chars) \{ goes to \{ (2 chars) This is illogical. How to go to just one character { in these cases. No I don't accept \$ this is missing the point. Expected result: ---------------- Please add { to list of acceptable ESCAPE sequences. \{ -> always got to single { character and stop the following $ processing. Effectively, this ESCAPE WAS in old version. But you didn't realize it when you added code to produce BAD ESCAPES. You forgot that \{ was an escape in old version. So just add it and document it. That will solve all issues. [23 Oct 11:06pm UTC] j...@php.net You're couple of years too late. Still not a bug. Correction: Expected result: ---------------- Please add { to list of acceptable ESCAPE sequences. \{ -> always go to single { character and *continue* the following $ processing as if { } were not present. BTW. This is not couple year too late. This is brand new suggestion. I am only trying to help customers. Please do not close this case so suddenly, I was just in middle of adding more info about the correction as stated above. The more you just slam dunk your customers, the more you obviously don't care about the hard work we do to help customers. Cheers, Ron Lentjes LC CLS. N.B.Please REVIEW this. Backwards compitibility is a very important issue and can keep from customers flaring up about hours and hours of rework which costs them enormous amounts of revenue. You keep telling the to upgrade but your upgrades keep busting sites. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49980&edit=1
