Hi guys,

After a discussion in the list, I've reread the manual page (http://www.php.net/str_replace) and the comments, checked Google, but need some confirmation.

When using an array as the search argument in str_replace(), the array is processed first to last. As expected, but this behaviour is not documented and therefor not reliable for my project.

$s = "Input\r\nMore input\rSome more\nEtc";
echo str_replace(array("\r\n", "\n", "\r"), '<BR>', $s);

This works as expected (putting exactly one <BR> between every line of input). Related comment on the manual page is from "jr at adslate dot com (03-Jun-2004 02:52)".

But since it's not documented, I can't rely on this. If the order of replacement is ever switched, my code stops working properly.

Now I have to do this, to process all OS specific line breaks correctly:
$s = str_replace("\r\n", "\n", $s);
$s = str_replace("\r", "\n", $s);
echo str_replace("\n", '<BR>', $s);

Can you guys please document the order of handling the search array?

Thanks a bunch for all of your work.
