Trailing Spaces Problem

Hi, I have a code here as the following: <?php $string="1 0 70.208 61.613 1.424 3.689 61.404 0.000 0.000 0.000 0.000 0.000"; $data= explode("\t", $string); echo "1: ". $data[0] . " 2: " . $data[1] . " 3: " . $data[2] . " 4: " . $data[3] . " 5: " . $data[4] ?> When I execute it, I get this error and output: PHP Notice: Undefined offset: 2 in /root/Desktop/test.php on line 8 PHP Notice: Undefined offset: 3 in /root/Desktop/test.php on line 8 PHP Notice: Undefined offset: 4 in /root/Desktop/test.php on line 8 1: 1 2: 0 70.208 61.613 1.424 3.689 61.404 0.000 0.000 0.000 0.000 Is there some way that I can have it so that it can print out: 1: 1 2:0 3: 70.208 4. 61.613 5. 1.424 I tried using \s for trailing spaces, but It all gave me output of everything in the single line. Have I missed something here? Thanks in advance.
