Keep option value selected after button click

On new search, I don't want it to reset to Monday. I want it to go after what's in my

$dag = $_GET["vdag"];


I think I'm close, but I can't find out what I'm missing. Any suggestions?

<form class="form-horizontal" method="get">
<div class="control-group">
<div class="controls form-inline"
<label for="inputValue">Choose day</label>
<select class="form-control" id="sel1" name="vdag">
<option value="1" <?= ($dag === 1 ? 'selected="selected"' : '')?>>Monday</option>
<option value="2" <?= ($dag === 2 ? 'selected="selected"' : '')?>>Tuesday</option>
<option value="3" <?= ($dag === 3 ? 'selected="selected"' : '')?>>Wednesday</option>
<option value="4" <?= ($dag === 4 ? 'selected="selected"' : '')?>>Thursday</option>
<option value="5" <?= ($dag === 5 ? 'selected="selected"' : '')?>>Friday</option>
</select>
<button type="submit" class="btn btn-default" value="Search">
<i class="glyphicon glyphicon-search"></i> Search
</button>
</div>
</div>
</form>

<?php
$dag = $_GET["vdag"]; <------ Here I get my number , 1 to 5
<!-- And more php code!-->


Sorry if I'm not clear.
