[RESOLVED] processing text area into csv format

[newbie271]

Hi
I have a form with a text area that may accepts words as input.
for example:

aaa
    bbb 

ccc

I want to convert it to string in the form "aaa, bbb, ccc".
The code that I wrote is as follows.

<form name="inpform" method="post" enctype="multipart/form-data" action = 'try2.php' > 
<textarea name="textArea" cols="40" rows="6">Enter your Input</textarea>
<input type="submit" value="submit" > 

//try2.php

<?php
$textarea = $_POST['textArea'];  

print"textarea before is $textarea"; //prints:  aaa bbb ccc
$regex = "[ \n\r\t]+";  //done to strip white spaces  

$textarea = explode($regex, $textarea);
print ("<br>textarea after is: $textarea<br>"); // prints:   Array

$comma_separated  = implode(',', $textarea);	
print ("<br>$comma_separated "); // does not work:  aaa bbb ccc
?>

help appreciated
Thanks

One problem I see is that you're using what almost looks like a regular expression (hint: you're missing pattern delimiters) with a function - namely [man]explode/man - that doesn't use regular expressions.

Perhaps you meant to use something like [man]preg_split/man instead?

Thanks bradgrafelman,
It worked.
The corrected code is given below:

<?php
$textarea = $_POST['textArea'];
print"textarea is $textarea";
$textarea = preg_split('/[ \n\r\t]+/', $textarea);
print ("<br>textarea after is: $textarea<br>");

$comma_separated  = implode(',', $textarea);	
print ("<br>comma_separated  is $comma_separated ");
?>
