#43811 [NEW]: Line Continuation Characters inside string are being removed
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.
