Splitting post data by \n not working

[unkwntech]

I have a textbox that is posting a list of items (one per line) when I attempt to split that list into an array with this code:

$answers = preg_split('/[\r\n]+/', $_POST['answers'], -1, PREG_SPLIT_NO_EMPTY);

where

$_POST['answers'] = "red\ngreen\nblue";

`$answers` results in an empty array.

I have also tried

$answers = explode("\n", $_POST['answers']);

which resulted in an array with a single empty element.

Nope.

This code

$_POST['answers'] = "red\ngreen\nblue";
$answers = explode("\n", $_POST['answers']);
print_r($answers);

works just dandy for me...returning Array ( [0] => red [1] => green [2] => blue )

 

BUT:  I am a freelance PHP developer. Freelance does not mean that my work is free.  If I help that means I took time away from making money, please don't be grumpy.  And I may or may not have tested my code, if I posted it then most likely my IDE said the syntax was correct however that does not mean that it works.

 

I just had to throw that in there, because, you just never know when someone is gonna sue you for giving them code that doesn't work
