Question

i am so stuck , please someone help if you have 2 min.

i have a foreach where I get values from session something like

foreach ($result as $i => $item ) {

         $values_array  = explode("\n",$get_widths); // outputs Array ( [0] => 120 [1] => 180) 
         // here I need to echo the value from the array but only ONCE
}

the issue is that this is used by 2 or more items and array outputs gets repeated every time , so if 2 items i get
Array ( [0] => 120 [1] => 180) Array ( [0] => 120 [1] => 180) or
120 120
instead

120 180

for actual code see here

<?php
foreach ($list as $i => &$item){
    $i=0;
    $is_group                   = $item_params->get('is_group');    
    $group_widths               = $item_params->get('group_widths');    
    $group_widths_array         = explode("\n",$group_widths);

    if($is_group == 1){

        echo $group_widths_array[$i];
    }



}
?>

please note I cant move outside the foreach. thank you

I am completely missing the point of this loop…

You are iterating over an array, assigning the key to $i and the value to $item but then you set $i to 0, echoing $group_widths_array[0] every time your condition is met and $item you don´t use at all…

That can´t be right, can it?

Anyway, it seems to me that the reason that your output is repeated is that you output $group_widths_array[0] every time and $is_group is the same on every iteration.
