Solution Code:

$i = 1;
while( $i <= $instance['posts_num'] ) {
    $array['tab'.$i.'_title'] = 'Category Heading';
    $array['tab'.$i.'_thumb'] = 'Insert link here';
    $array['tab'.$i.'_featured'] = 'Insert link here';
    $array['tab'.$i.'_description'] = 'Insert category desciption';
    $array['tab'.$i.'_link'] = 'Insert category link';          
$i += 1;
}   

$instance = wp_parse_args( (array)$instance, array(
    'heading' => 'Featured Area', 
    'title' => '',
    'posts_num' => 1,

    (array) $array
) );

how can I create array with while loop.

I am trying to create an array with the help of while loop in simple wordpress plugin. my codes are below:

    $instance = wp_parse_args( (array)$instance, array(
        'heading' => 'Featured Area', 
        'title' => '',
        'posts_num' => 1,

        $array = array();

        $i = 1;
        while( $i <= $instance['posts_num'] ) {

            $array[] = 'tab'.$i.'_title' => 'Category Heading',
            $array[] = 'tab'.$i.'_thumb' => 'Insert link here',
            $array[] = 'tab'.$i.'_featured' => 'Insert link here',
            $array[] = 'tab'.$i.'_description' => 'Insert category desciption',
            $array[] = 'tab'.$i.'_link' => 'Insert category link',

        $i += 1;
        }

    ) );

I just want to confirm if i am doing correctly.

I want to generate array like this :

'tab1_title' => 'Category Heading',
'tab1_thumb' => 'Insert link here',
'tab1_featured' => 'Insert link here',
'tab1_description' => 'Insert category desciption',
'tab1_link' => 'Insert category link',

'tab2_title' => 'Category Heading',
'tab2_thumb' => 'Insert link here',
'tab2_featured' => 'Insert link here',
'tab2_description' => 'Insert category desciption',
'tab2_link' => 'Insert category link',

Answer 1

You're trying to put a while loop inside array() . That's just not going to work. Construct the array before the call to wp_parse_args and then pass your finished array in.

Answer 2

while( $i <= $instance['posts_num'] ) {


            $array["tab{$i}_title"] = 'Category Heading';
            //...Repeat for others here.


        $i += 1;
        }



array(4) {
  ["tab0_title"]=>
  string(16) "Category Heading"
  ["tab1_title"]=>
  string(16) "Category Heading"
  ["tab2_title"]=>
  string(16) "Category Heading"
  ["tab3_title"]=>
  string(16) "Category Heading"
}

Answer 3

The problem with your code is that you are using a wrong syntax/logic.

Example :

$array['tab'.$i.'_title'] = 'Category Heading';
$array['tab'.$i.'_thumb'] = 'Insert link here';
$array['tab'.$i.'_featured'] = 'Insert link here';
$array['tab'.$i.'_description'] = 'Insert category desciption';
$array['tab'.$i.'_link'] = 'Insert category link';
