how to array replace?

[Monkuar]

Here is my code

 

if (isset($_GET['hide'])){

$id = intval($_GET['hide']);
$explode = explode(",", $_COOKIE['hide']);

if (in_array($id, $explode)) {


}
setcookie('hide', ''.$id.'',time()+32000000);
header('Location: index.php');
exit;
}

 

My Explanation:

 

If somone clicks ?hide=2

 

It will add the cookie hide, and the value to 2.  Now, if somone clicks ?hide=1, I need it to add 2,1  how is that possible?

 

 

Then if the in_array is correct, (Means if the value of the cookie is 2 and they clicked ?hide=2) how do I take that number "2" out of the it (Remove it) and make a new array that will be inserted to my $id variable?

[marcus]

$id = 2;
$array = array(1,2,3);

if(in_array($id, $array)){
    $array = array_diff($array,array($id));
}

$cookie = setcookie('hide', implode(',', $array), time()+32000000);

 

My approach...

 

$id is my equivalence to your get variable, $array is my equivalence to your $explode variable.

 

If the $id in the $array -> redefine $array as the difference between the current $array and a new array containing the $id. Then change the cookie's value from "1,2,3" to "1,3"

Stop creating thread after thread after thread for the exact same problem! It's annoying!

[Monkuar]

$id = 2;
$array = array(1,2,3);

if(in_array($id, $array)){
    $array = array_diff($array,array($id));
}

$cookie = setcookie('hide', implode(',', $array), time()+32000000);

 

My approach...

 

$id is my equivalence to your get variable, $array is my equivalence to your $explode variable.

 

If the $id in the $array -> redefine $array as the difference between the current $array and a new array containing the $id. Then change the cookie's value from "1,2,3" to "1,3"

 

Hey, this works but what if I want to add to the array instead of take away stuff? Is there a different function for that?

 

I added this

 

else{
setcookie('hide', ''.$id.'', time()+32000000);
}

 

to the end, so it can just add the ?hide=1 if somone clicked, so it will actually set my cookie value, but then now if the user clicks on ?hide=2, it will launch this again because that $id is not matching the in_array

Adding to an array is just using the square bracket syntax.

 

$array = array(1,2,3);
$array[] = 4;
// array is now [1,2,3,4]

Okay awesome

 

if (isset($_GET['hide'])){
$id = intval($_GET['hide']);
$explode = explode(",", $_COOKIE['hide']);


$id = $id;
$array = $explode;

if(in_array($id, $array)){
    $array = array_diff($array,array($id));
setcookie('hide', implode(',', $array), time()+32000000);
}else if ($_COOKIE['hide'] AND $explode['1'] AND $explode['2']){
setcookie('hide', ''.$explode['0'].','.$explode['1'].','.$explode['2'].','.$id.'', time()+32000000);
}else if ($_COOKIE['hide'] AND $explode['1']){
setcookie('hide', ''.$explode['0'].','.$explode['1'].','.$id.'', time()+32000000);
}
else if ($_COOKIE['hide']){
setcookie('hide', ''.$explode['0'].','.$id.'', time()+32000000);
}
else{
setcookie('hide', ''.$id.'', time()+32000000);
}

header('Location: index.php');
exit;
}
