drop-down list showing values multiple times
Question
I have a array in php - array and I am using the follwing code to create a drop-down list for this array -
<html>
<head>
</head>
<body>
<form method="post" action="test.php">
<select name="feature" id="Feature">
<?php
$i=0;
foreach($newFeature as $feat)
{
?>
<option value="<?php echo $feat;?>"><?php echo $newFeature[$i];?></option>
<?php
$i++;
}
?>
</select> <input type="submit" name="submit" value="Test">
</form>
</body>
</html>
The drop-down list contains values twice. Here after traversing the array once and showing the values, code again traverse the value and show them again.
what I am doing wrong here ? please guide.

In my hopinion, you have a little bit confused the foreach with the for loop.
In you case, saying $newFeature[$i] or $feat is actually refering to the same thing.
Therefore, try this:
<html>
<head>
</head>
<body>
<form method="post" action="test.php">
<select name="feature" id="Feature">
<?php
foreach($newFeature as $feat)
{
?>
<option value="<?php echo $feat;?>"><?php echo $feat;?></option>
<?php
}
?>
</select> <input type="submit" name="submit" value="Test">
</form>
</body>
</html>

Show us the $newFeature array. Also, why do you need the $i variable?
$newFeature[$i]

Here is a more cleaner way to generate the list, also you are using for each in a wrong way.
<form method="post" action="test.php">
<select name="feature" id="Feature">
<?php foreach($newFeature as $feat): ?>
<option value="<?php echo $feat; ?>"><?php echo $feat; ?></option>
<?php endforeach; ?>
</select>
<input type="submit" name="submit" value="Test">
</form>

if you are using foreach no need for counting and you should use $feat instead
<?php
foreach($newFeature as $feat)
{
?>
<option value="<?php echo $feat;?>"><?php echo $feat;?></option>
<?php
}
?>

Using $newFeature[$i] is a wrong way of using foreach loop. please post a snapshot of the array or try the following.
To debug and rectify the issue
Print the $newFeatures array before using the foreach and debug the code.
Or
2.Add the following line in front of the foreach loop
<?php $newFeature = array_unique($newFeature); ?>
This way might solve your problem. I still recommend you to use the first suggestion and debug your code.
