PHP无意中剥离了MySql TEXT中的换行符

Question

I have a TEXT column within my MySql database with the content of:

test

testing

tested

however...

when I refer to the content within the column...

$queryTHREAD = "SELECT * FROM FusionNotes ORDER BY 'When'";
$resultTHREAD = mysqli_query($db, $queryTHREAD); 
$rowsTHREAD = mysqli_num_rows($resultTHREAD);
while ($rowTHREAD = mysqli_fetch_assoc($resultTHREAD)) {
    $test = $rowTHREAD['What'];
    echo($test);

It returns:

testtestingtested

I want to retain the however I have no idea why it's stripping.

Any Ideas?
