for循环执行php代码错误

Question

i'm using this function http://php.net/manual/en/function.getopt.php to do this

$options = getopt(array('c::'), array('chunk::'));
var_dump($options);

this code located in a file called do.php and i using this shell command to print the result

for i in `seq 2`;do php /home/user/public_html/do.php --chunk=$i ;done

the result is

array(2) {
  ["chunk"]=>
  string(1) "1"
}
array(2) {
  ["chunk"]=>
  string(1) "1"
}

how that happend? it should

array(2) {
  ["chunk"]=>
  string(1) "1"
}
array(2) {
  ["chunk"]=>
  string(1) "2"
}

(PHP VERSION 5.4.45)

As you can see in the documentation, the description of getopt is:

array getopt ( string $options [, array $longopts ] )

So the first parameter must be a string instead an array:

<?php
$options = getopt('c::', array('chunk::'));
var_dump($options);
