Your values are stored in array so you have to display it using array indexes.

<select name="fieldforpost">
  <option value="<?php echo $array_variable[0]; ?>">id name 1</option>
  <option value="<?php echo $array_variable[1]; ?>">id name 2</option>
  <option value="<?php echo $array_variable[2]; ?>">id name 3</option>
  <option value="<?php echo $array_variable[3]; ?>">id name 4</option>
  <option value="<?php echo $array_variable[4]; ?>">id name 1</option>
</select>

Remember that in PHP array indexes starts at 0 not 1. Or you can use the foreach loop:

<select name="fieldforpost">
  <?php foreach($array_variable as $variable) : ?>
      <option value="<?php echo $variable; ?>">id name <?php echo $var; ?></option>
   <?php endforeach; ?>
</select>

If you want to read the form data:

$output_array = $_POST['fieldforpost'];

Make sure that your form has method set to POST. If you leave the method blank, it will use GET.

In order to post form fields you need to set an action and post method for the form. For example, if you wanted to post the form to the same page you are on now you would use: 

<form action="<?php $_SERVER['PHP_SELF'] ?>" method="post">
  <select name="fieldforpost">
    <option value="<?php $array_variable_1; ?>">id name 1</option>
    <option value="<?php $array_variable_2; ?>">id name 2</option>
    <option value="<?php $array_variable_3; ?>">id name 3</option>
    <option value="<?php $array_variable_4; ?>">id name 4</option>
    <option value="<?php $array_variable_5; ?>">id name 1</option>
  </select>
  <input type="submit" name="submit" value="Submit Form">
</form>

After submitting the form the page will reload and $output_array = $_POST['fieldforpost']; should work correctly (assuming a value was selected on the form).

Now, if you want to dynamically populate the options from the array you can do something like this:

<select name="fieldforpost">
  <?php 
    foreach($array_variable as $var) {
      echo "<option value=\"$var\">id name $var</option>";
    }
  ?>
</select>

Just put echo in values

<select name="fieldforpost">
  <option value="<?php echo  $array_variable_1; ?>">id name 1</option>
  <option value="<?php echo $array_variable_2; ?>">id name 2</option>
  <option value="<?php echo $array_variable_3; ?>">id name 3</option>
  <option value="<?php echo $array_variable_4; ?>">id name 4</option>
  <option value="<?php echo $array_variable_5; ?>">id name 1</option>
</select>
