I have a string like this,
sidePanel[]=1&sidePanel[]=2&sidePanel[]=4
And if I need to add another value to the string I do this:
$sidePanel = explode('&', $_SESSION['sidePanel']);
array_push($sidePanel, 'sidePanel[]=3');
$sidePanel = implode('&', $sidePanel);
Which returns this:
sidePanel[]=1&sidePanel[]=2&sidePanel[]=4&sidePanel[]3
Now how can I make it so that it will always insert after the array 'sidePanel[]=2' when I explode it at &?
I do not want it in numerical order although this example will return it in numerical order, as the string can change to be in any order.
I cannot use array_splice as I understand this uses the key of the array, and as the position of sidePanel[]=2 can change it will not always be the same.
