#23636 [Csd]: overriding auto_detect_line_endings

ID: 23636 Updated by: wez@php.net Reported By: mitra at mitra dot biz Status: Closed Bug Type: Feature/Change Request PHP Version: 4.3.1 New Comment: It is worth noting that: ini_set('auto_detect_line_endings', true); is only inspected and used by the stream when it reads the *first* line (via fgets). Subsequent reads use the value it detect then. This is only an issue if (for some strange reason!) you have a mixture of different line ending conventions in a file. In other words, the ini setting is only inspected at the time the stream is opened via fopen() or fsockopen().

There is nothing on the ref.filesystem page, nor any link from PHP_INI_ALL to something that explains what it means. (not intending to be critical, but as someone whose done a lot of PHP programming, and was explicitly looking for a programatic way to set this variable, I couldn't find it). ------------------------------------------------------------------------ [2003-05-16 01:48:38] philip@php.net The documentation already shows it as being PHP_INI_ALL so why did you feel it implies otherwise? http://www.php.net/manual/en/ref.filesystem.php ------------------------------------------------------------------------ [2003-05-15 23:23:18] mitra at mitra dot biz Thanks - so maybe the docs should be updated to show that a) the settings are settable, the implication is that they can only be set in php.ini b) the stream_get_line alternative to fgets Oops - since this is OpenSource documentation, maybe I should do it ...... done ------------------------------------------------------------------------ [2003-05-15 19:12:13] pollita@php.net This option *IS* settable within your PHP scripts. Example: <?php ini_set('auto_detect_line_endings', true); $contents = file('unknowntype.txt'); ini_set('auto_detect_line_endings', false); $content2 = file('unixfile.txt'); ?> Note, with PHP 4.3 anytime Mac files are read using fgets or file you'll need to auto_detect_line_endings since \n is otherwise assumed. However, with PHP 5.0, stream_get_line() will allow you to specify what line ending character to read up to. \\ Read a line from a MAC file stream_get_line($fp, 4096, "\r"); \\ Read a line from a UNIX file stream_get_line($fp, 4096, "\n"); \\ Read a line from a DOS file stream_get_line($fp, 4096, "\r\n"); \\ Read a line up to any filesystem line ending ini_set('auto_detect_line_endings', true); fgets($fp); \\ You can also make up your own line ending characters: \\ Read up to the first instance of ":" stream_get_line($fp, 4096, ":"); ------------------------------------------------------------------------ [2003-05-15 02:21:39] mitra at mitra dot biz I'm often running into problems with users, moving files around from a Macintosh to Linux, it would be useful if PHP allowed modification of auto_detect_line_endings in the php3, rather than just in php.ini. In this way, files which handle user supplied files, can do the auto-detection, while those reading files of known origin can leave it as it is. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23636&edit=1
