Holy sh*t! Seriously? Since it became a HTML specification back in 1999, that must be quite some old software. I just assumed people upgraded by then, so it wouldn't be a problem at all. Not too sure if it's the best "economically-challenged" way to go, since they're probably waiting for ever to get their system booted, but that's a different story. Do you happen to know their browser specs? I've went through the list of browsers visiting our website (based on JS statistics).

Of course! But are all my users going to run out and upgrade because some W3C weenie (from their persepctive) told them to? No. In fact, *some* of my users are so economically-challenged that their hardware doesn't support a W3C-compliant browser due to memory constraints.

Sure, but in newer versions, they might update their code to follow

True; and I haven't tested the code either, to be honest. I found the
basic implementation on a forum somewhere and adapted it to the
threadstarter's need.
I might try and see if I could submit a documentation bug on this. I think
it's a useful feature and you're right to claim that since it's not
documented, one should not rely on it.

Hey, totally agree here, BUT, the threadstarter doesn't mention it being
put in a database. Actually, he just requests it to be written on a new
line in the output. I just provided him a way of doing this.
I always store the input directly in the database (quoted, then, of
course) and replace \r\n with when needed (display on screen). I've
had no problems by strictly using \r\n yet. But as I have an open source
project, I assume someone will (be telling me||submit a bug) if they have
problems. In that case, I will implement a non-W3C compliant hack ;)

Two problems here.
This assumes a specific undocumented ordering to the replacement in
processing the array argument. If, for some insane reason, the PHP
implementation of str_replace chooses to process that input array in
reverse order, you would end up with double for "\r\n" input.
This is incredibly unlikely, but it's NOT (yet) documented that the
arrays are processed in order.
The next problem is that replacing newline (in any form) with on
the INPUT phase of your program is just a Bad Idea. :-)
The INPUT data should be kept sacrosanct and the OS-dependent newlines
should be converted to newlines.
If the data is output later to a browser, nl2br() should be used.
Because someday you may want to output that same data to RSS, XML, or
XYZ, in which case is NOT what you want for your newlines.

//The order of operations is crucual here:
$string = str_replace("\r\n", "\n", $string);
$string = str_replace("\r", "\n", $string);
You could use arrays for str_replace, and reduce the function calls,
but that relies on the ORDER in which the array/substitutions are
processed.
While I can't imagine the array version of str_replace doing them in
reverse order, it is not currently a documented behaviour, so I
personally would just take the penalty of 2 function calls, unless
it's a proven performance problem (which seems unlikely).
YMMV

I've tested this on different distros and browsers, all had sent \r\n and
in years I've not had any problems with not receiving \r\n. But I did some
extensive searching, and I found this in the W3C specifications:
"Line breaks, as in multi-line text field values, are represented as "CR
LF" pairs, i.e., `%0D%0A'."

Well, if it's true that some browsers on some platforms ignore the W3C
standard, I guess we could use:
$datelist = str_replace(array("\r\n","\n","\r"),'',$_POST['datelist']);

Actually, I know that it's browser/OS dependent, cuz I had a bunch of

This may be true only of OS 9, and you may not care about them

Actually, I know that both Windows and Linux send a linebreak in a textarea as
"\r\n", not "\n". I assume it's all the same for all platforms, and that Mac
would send "\r\n", too.

'\r\n' and "\r\n" are not anything alike...
\r\n only have special meaning inside of ", not '
If you want to cover all browser/OS combinations, you'd want to
pre-treat the text area input like:
$datelist = $_POST['datelist'];
$datelist = str_replace("\r\n", "\r", $datelist);
$datelist = str_replace("\r", "\n", $datelist);
Now all the date are separated by "\n" and you can reliably use
explode("\n", $datelist); on them.

You'll need to use "\r\n", with double quotes. Single quotes don't
interpret the \r\n the same.

You might also want to try:
$string=preg_split('/\s+/', $datelist);
which would split on any (one or more) whitespace character(s).

If the user separates the dates by an enter in the textarea, you need to
explode on "\r\n". To be able to handle both, you need to use split() or
preg_split().
When I use
$datelist=$_POST[datelist];
$string=explode('\r\n',$datelist);
echo $string;
foreach ($string as $value) {
echo "Date: $value\n";
this is what I get:
ArrayDate: 24/12/2018 26/12/2018 31/12/2018 14/02/2019 14/03/2019 20/06/2019
24/06/2019 26/06/2019 27/06/2019 27/06/2019
This solved the issue, although I find it rather bizar:
$datelist=$_POST[datelist];
$string=preg_split('/\r\n/', $datelist, -1, PREG_SPLIT_OFFSET_CAPTURE);
echo $string;
foreach ($string as $value) {
echo "Date: $value\n";
}
Btw the input is a copy/paste from within a program

If the user separates the dates by an enter in the textarea, you need to
explode on "\r\n". To be able to handle both, you need to use split() or
preg_split().

Re: [PHP] break up variable and put each element in an array

A. I have a page on which people can supply dates in a text area. Dates
are
entered like this:
3/01/2005
29/12/2005
2/01/2006
20/02/2006
28/12/2006
1/01/2007
15/02/2007
B. Now I need this Post element to be broken into pieces (per date) and
each
of those pieces should be put into a text so the outcome (echo on screen)
would be like this:
Date=3/01/2005
Date=29/12/2005
Date=2/01/2006
Date=20/02/2006
Date=28/12/2006
Date=1/01/2007
Date=15/02/2007
The posted variable from A looks like this (when written on screen):
3/01/2005 29/12/2005 2/01/2006 20/02/2006 28/12/2006 1/01/2007 15/02/2007
So I need break this up and store any individual date into a key of an
array
Afterwards I need to loop through this array and use the value of each key
to be printed after 'Date='
try this:
$string = "3/01/2005 29/12/2005 2/01/2006 20/02/2006 28/12/2006 1/01/2007
15/02/2007";
$array = explode(' ', $string);
foreach ($array as $value) echo "Date: $value";
