Re: PHP 4.0 Bug #6080 Updated: fsockopen example uses "\n" for HTTP communication

Just what is used as a newline may vary from OS to OS. Unix traditionally uses \012', one type of DOSish I/O uses \015\012', and Mac OS uses `\015'. Perl uses `\n' to represent the "logical" newline, where what is logical may depend on the platform in use. In MacPerl, \n' always means \015'. In DOSish perls, \n' usually means \012', but when accessing a file in "text" mode, STDIO translates it to (or from) `\015\012', depending on whether you're reading or writing. Unix does the same thing on ttys in canonical mode. `\015\012' is commonly referred to as CRLF. Because of the "text" mode translation, DOSish perls have limitations in using seek' and tell' on a file accessed in "text" mode. Stick to seek'-ing to locations you got from tell' (and no others), and you are usually free to use seek' and tell' even in "text" mode. Using `seek' or `tell' or other file operations may be non-portable. If you use binmode' on a file, however, you can usually seek' and `tell' with arbitrary values in safety. A common misconception in socket programming is that \n' eq \012' everywhere. When using protocols such as common Internet protocols, \012' and \015' are called for specifically, and the values of the logical \n' and \r' (carriage return) are not reliable. print SOCKET "Hi there, client!\r\n"; # WRONG print SOCKET "Hi there, client!\015\012"; # RIGHT [...] However, PHP is buggy with newlines. It makes \n always to LF which is wrong on MacOS and DOS/Win32, as reported in Bug: 6079. It should be \x0d\x0a oder \015\012 or something alike, otherwise it will break again if bug 6079 is fixed. regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://www.bjoernsworld.de am Badedeich 7 · Telefon: +49(0)4667/981ASK · http://bjoern.hoehrmann.de 25899 Dagebüll · PGP KeyID: 0xA4357E78 · http://learn.to/quote <---
