How to Remove Carriage Return in Array

[soma56]

I'm trying to remove blank spaces after a textarea submit. For example:

 

Blank space

Blank space

text1(enter key pressed)

text2(enter key pressed)

text3(enter key pressed)

Blank space

Blank space

 

Everything I've researched says something like this should work (Confused as to why it's not):

 

foreach ($mytextarea as $e) {
if ($e == "") {
$e = preg_replace( '/\r\n/', '', $e);
}
}

 

I also thought a string replace would do the trick after checking the length:

 

function validElement($element) {
    return strlen($element) > 1;
}

$mytextarea = array_values(array_filter($mytextarea, "validElement"));
$mytextarea = str_replace("\r",'',$mytextarea; 

 

Neither seem to be working as when I:

count($mytextarea);
echo $mytextarea;

 

I always see the extra 'return' as values in the array.

Assuming that $mytextarea is an array, doing this

<?php
$mytextarea = array_map('trim',$mytextarea);
?>

should work.

Thanks Ken, I appreciate it but it didn't work. I discovered that this did for anyone looking:

 

<?PHP
//Bring in Array Data
$mytextarea = explode("\n", $_POST['mytextarea']);

//Remove Return
$mytextarea = str_replace("\r",'',$mytextarea) ;

?>

 

The only difference from my original post, and likely what hindered the function correctly, is that I placed the 'str_replace' right after the $_POST.
