So I have a need to generate md5 hashes for multiple lines out of a textarea.
The problem is all of the individual "\n" lines are returning incorrect md5 outputs EXCEPT for the last line (it always returns the correct md5 output)

Here is the code and a sample input/output test at the bottom:

The HTML form

<form action="hash.php" method="post">
	
<textarea name="hashed" rows=20 cols=41></textarea></br>
<input type="submit" value="Generate">
</form>

PHP code used to take individual \n lines and generate the individual line md5 output

$data = $_POST['hashed'] ;
foreach(explode("\n", $data) as $line) {
$hashedData = hash('md5',$line, FALSE);
echo '<strong>'. $hashedData .'</strong></br>';
}

1. You'll notice the first line (apple) generates "md5(apple + something else)" (I'm thinking the actual \n is generated as part of apple hence wrong output)
2. Same thing happens to orange
3. The third line (apple) generates the correct "md5(apple)" output

Sample input:
apple
orange
apple

Sample output:

Any suggestions or a possible workaround?


A few things already tried:
- using commas as a separator but it didn't work out too well
- tried reverse-md5'ing the wrong output but no one has yet to rainbow it
- Clean $line from enter \n spaces and %20 spaces, no dice
$clean = str_replace(' ','',$str);
