Description: ------------ Odd edge case, but could be fairly typical for creating SQL statement strings, causes a PHP warning from the Squiz's Strings/DoubleQuoteUsageSniff. From experimenting with my test file, these characteristics seem necessary: - a string portion that contains a $variable inside literal singlequotes ===> bar = '$z', - a string portion that contains a variable outside of the doublequotes that is attached via concatenation, but whose surrounding string portions include the literal single quotes around it ===> baz = '" . $a . "'..." - the newline that splits the singlequoted variable piece from the doublequoted variable piece Test script: --------------- <?php $x = "bar = '$z', baz = '" . $a . "'..."; ?> Expected result: ---------------- phpcs --standard=Squiz --report=summary test.php PHP CODE SNIFFER REPORT SUMMARY -------------------------------------------------------------------------- FILE ERRORS WARNINGS -------------------------------------------------------------------------- test.php 4 0 -------------------------------------------------------------------------- A TOTAL OF 4 ERROR(S) AND 0 WARNING(S) WERE FOUND IN 1 FILE(S) -------------------------------------------------------------------------- Actual result: -------------- PHP Warning: Unexpected character in input: ''' (ASCII=39) state=1 in PHP/CodeSniffer/Standards/Squiz/Sniffs/Strings/DoubleQuoteUsageSniff.php on line 65 PHP Stack trace: PHP 1. {main}() phpcs:0 PHP 2.

That "Warning" line should be showing line 65, not 66, so that all references to DoubleQuoteUsageSniff.php should show 65.

Thank you for taking the time to report a problem with the package. This problem may have been already fixed by a previous change that is in the SVN of the package. Please checking out the SVN repository of this package and upgrade svn checkout svn.php.net/repository/pear/packages/PHP_CodeSniffer/trunk pear upgrade package2.xml or pear upgrade package.xml If you are able to reproduce the bug with the latest SVN, please change the status back to "Open". Again, thank you for your continued support of PEAR. I'm not getting this with the SVN version. I fixed something related in another sniff, but don't see a specific fix for this.

The current SVN still throws the same PHP Warning against my test script. I think the recent change (February) that helps with bug #17237 was done directly in the other reported sniff (Generic.CodeAnalysis.UnusedFunctionParameter), whereas nothing has changed since October in this sniff (Squiz.Strings.DoubleQuoteUsage).

Looks like the reason I can't replicate is my PHP version (5.3.0). I can get this to break on 5.2.6.

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.

Confirmed that this change clears the notices on the test file for me on PHP 5.2.4... thanks Greg!
