Flatten your array by looping through it

$aFlattened = array_merge($aFlattened, $aOperators);
}

Given this PHP array:
$options['systems'] = array(1, 2, 3)
How would I append the value 4 to the $systems array within the $options array?
You could use array_push to push additional items like so:
array_push($options['systems'], 4);
Or the shorthand version:
$options['systems'][] = 4;
You can use php array_push function. Like this. array_push($options['systems'],4);
you can read the detail of array_push from below link.array_push manual

My chain in PHP is like the following:
$chain = "m=toto&i=12&a=new";
How to get m, i and a values ?
Thanks.
Try This:
<?php
$chain = "m=toto&i=12&a=new";
parse_str($chain,$array);
This will create an array named $array containing all values you can access them as $array['m']
You can Print all this by:
print_r($array);
