array help needed

[spires]

Hi

 

I'm trying to separate each line of a text filed and place each line in to an array one by one.

At the moment i'm just trying get echo out the count of how many items a are in the array $expKey;

 

When entering the words in the text field, i'm pressing return to move doen to the next line.

I'm adding 4 lines of text. So, the count should be 4.  Or am I missing something?

 

 

         $expKey = explode("/n", $_POST['keywords']);
 echo  count($expKey). '  ';

 

Thanks

OK, I have a work around, but i'm sure the other way should work fine.

 

So, if you have another / better way to do it, please let me know. 

 

Work Around

$expKey = explode("<br />", nl2br($_POST['key_'.$i]));

this:

$expKey = explode("/n", $_POST['keywords']);

 

does not work, because the correct newline character is "\n" and not "/n"

just use file() This takes a file and returns an array of each different line, which is exactly what you want if im not mistaken

 

EDIT: Sorry misread your post. Yeah you are using the wrong newline character (\n not /n) as webstyles pointed out
