i have this one in my code

$droparray=array("2004 / 2005",
				"2005 / 2006",
				"2006 / 2007",
				"2007 / 2008",
				"2008 / 2009",
				"2009 / 2010",
				"2010 / 2011",
				"2011 / 2012",
				"2012 / 2013",
				"2013 / 2014",
				"2014 / 2015",
				"2015 / 2016",
				"2016 / 2017",
				"2017 / 2018",
				"2018 / 2019",
				"2019 / 2020");
	$nondroparray=array("2012 / 2013","2005 / 2006");
	$newarray=array_diff($droparray,$nondroparray);
seasonselect="";
for ($x=0;$x<count($newarray)+1;)
{
$seasonselect .="<option value=\"$newarray[$x]\">$newarray[$x]</option>";
$x++;
}

now in my drop down i have this

 <select name='season'><?=$seasonselect?></select>

the problem is that
it display even an empty one

<select name="season">
<option value="2004 / 2005">2004 / 2005</option>
<option value=""></option> <!// should not display -->
<option value="2006 / 2007">2006 / 2007</option>
<option value="2007 / 2008">2007 / 2008</option>
<option value="2008 / 2009">2008 / 2009</option>
<option value="2009 / 2010">2009 / 2010</option>
<option value="2010 / 2011">2010 / 2011</option>
<option value="2011 / 2012">2011 / 2012</option>
<option value=""></option> // should not display
<option value="2013 / 2014">2013 / 2014</option>
<option value="2014 / 2015">2014 / 2015</option>

Wrap your call to [man]array_diff[/man] in an [man]array_values[/man]. This will re-index the array with the dropped elements removed.
