                                              'text' => TEXT_NO_PRODUCTS);

i want to make a condition whether there is a value in $list_box_contents[0][]["text"] .when i write the code if(!empty($list_box_contents[0][]["text"])). my IDE alet me there is an error. what’s wrong with it?

Answer 1

[] it’s not a position, index or something like this.

With

$list_box_contents[0][] = array('params' => 'class="productListing-data"',
                                              'text' => TEXT_NO_PRODUCTS);

you are pushing the array with its two value (and keys) on the right of the = in the last position of the subarray which has index 0. That is the structure you’ll have is:

$list_box_contents[0] => array(VALUES-BEFORE, [last-position-key] => array('params' => 'class="productListing-data"', 'text' => TEXT_NO_PRODUCTS))

Anyway to have an idea of what happens, you can use print_r($list_box_contents) or var_dump($list_box_contents)

after the lines you posted.
