From: steve1011 at att dot net Operating system: Windows 2003 server PHP version: 5.2.5 PHP Bug Type: Scripting Engine problem Bug description: Line Continuation Characters inside string are being removed
Description: ------------ If a string contains backslash newline, in any form of input or string building, those characters are removed as if the parser is processing a script line. All other languages that I know of only remove the line continuation if it occurs outside of a string definition and leaves the inside of strings alone (other than normal escape sequences of double quoted strings). php even strips the backslash newline from text submitted through a web form and referenced as $_REQUEST['varname']. Line continuation characters effected are: backslash newline backslash carriage return backslash equal sign backslash 0x10 There may be more. I haven't completed testing yet, but will update this bug report if I find more. Reproduce code: --------------- I've tried test strings (letter e, backslash, newline, letter e) like: "e\\\ne" becomes "ee" 'e\'."\n".'e' becomes 'ee' 'e\'.0x0a.'e' becomes 'ee' "e\\\x0ae" becomes "ee" you get the idea. If I [sic] escape the string like this: "e\\\\\x0a\x0ae" I get the expected [e, backslash, newline, e] string. -- Edit bug report at http://bugs.php.net/?id=43811&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=43811&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=43811&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=43811&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=43811&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=43811&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=43811&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=43811&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=43811&r=needscript Try newer version: http://bugs.php.net/fix.php?id=43811&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=43811&r=support Expected behavior: http://bugs.php.net/fix.php?id=43811&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=43811&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=43811&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=43811&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=43811&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=43811&r=dst IIS Stability: http://bugs.php.net/fix.php?id=43811&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=43811&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=43811&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=43811&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=43811&r=mysqlcfg
