</select>
I would like to select value based on $salary=$_GET['salary']; if $salary empty I need to select first one as selected

Answer 1

To set a default value for an HTML select element, you need to give the appropriate <option> element the selected attribute. It would look like this:
<option value='50000' selected='selected'>50,000</option>
In your PHP code, you would add this by setting a string for each option, to either "selected='selected'" or blank, depending on whether that option is the one you want to have selected.
This is obviously far easier to put into a loop rather than writing the same code twenty times, so you would need to rewrite your output to create a loop for creating your options.
Hope that helps.

You can do something like this on creation...[not tested]
<?php
$options = array(
'10000' => '10,000',
...
'150000' => '150,000'
); //From MySQL
array_unshift($options, '' => 'Any');
$salary = isset($_GET['salary'])?$_GET['salary']:'';
?>
<select name="salary" class="styled">
<?php foreach ($options as $value=>$text){ ?>
<option <?php if($value == $salary){echo 'selected="selected"'; }?> value="<?php echo $value; ?>"><?php echo $text; ?></option>
<?php } ?>
</select>

If I understand your question correctly you want that if the person doesn't select any thing you want 10000 to be automatically selected for him. And I also assume that the options in the select list are static. So..
<?php
if($_GET['salary']=='')
$salary = 10000;
else
$salary = $_GET['salary'];
?>
