mysqli_fetch_array to php variable trash - php

Question

I upload 4 photos in a folder, and the names of the photos on mysql. Then i "SELECT" the names of the files, and put them in the array picArray as shown. But when i try to echo the contents, although i take the right names, it seem that they cant be used as a directory path.
Here is the code:
$con=mysqli_connect("localhost","root","mypass","fixit");
$con->set_charset("utf8");
$repId=$repId+1;
$qr = mysqli_query($con,"SELECT * FROM photos WHERE report='$repId'");
$picArray = Array();
while( $row = mysqli_fetch_array($qr) ) {
$picArray[] = $row['name'];
}
?>
<div>
<img id="img1" src="uploads/<?php echo $repId ?>/<?php echo $picArray[0] ?>" />
<img id="img2" src="uploads/<?php echo $repId ?>/<?php echo $picArray[1] ?>" />
</div>
<div>
<img id="img3" src="uploads/<?php echo $repId ?>/<?php echo $picArray[2] ?>" />
<img id="img4" src="uploads/<?php echo $repId ?>/<?php echo $picArray[3] ?>" />
</div>
What i should mention, is that when i:
echo $picArray[0];
echo $picArray[1];
echo $picArray[2];
echo $picArray[3];
i get:
rafiki.png rafiki2.png
rafiki3.pngrafiki4.png
which means that the array has newline and spaces on it... Why is this happening?

Answer 1

There are probably new lines stored with the picture names in the database this is a fix but you should clean up you data
while( $row = mysqli_fetch_array($qr) ) {
$picArray[] = trim($row['name']);
}
