substr function in PHP5
<p>I am developing an application were I need to use the next PHP5 code: </p>

<pre><code>&lt;?php

$Hurrengo_Hitza = 'word_3';

$Handiena_MarkID = 0;  
$Handiena_Hitzarentzat = -2;
$Hitza_Index = substr($Hurrengo_Hitza , 5);

    print $Handiena_MarkID . $Hitza_index . $Handiena_Hitzarentzat;
</code></pre>

<p>The result I am looking for is <code>0 3 -2</code> and the result I am getting is <code>0-2</code>. Which is the problem?</p>
