Updating Serialized Arrays.

Updating a serialized array.

First off we all should know how to use serialize().

Serialize is a function that takes arrays into strings for easier storing.

So in this tutorial you will learn how to update a serialize array.

First off lets create our array:

Code:

<?php

$array = array(1 => "one");

?>

To serialize arrays all you do is put the array between the parameters for the serialize function like so:

Code:

<?php

$array = array(1 => "one");
$a = serialize($array);
?>

This will output the following:

Code:

a:1:{i:1;s:3:"one";}

Now lets unserialize the $a variable and update the array.

Code:

<?php

$array = array(1 => "one");
$a = serialize($array);

$arrah = unserialize($a);
?>

This above would output the array back into array form using $arrah to access its values.

Code:

<?php

$array = array(1 => "one");
$a = serialize($array);

$arrah = unserialize($a);

$arrah[1] = "uno";
$arrah[2] = "two";
$thearray = serialize($arrah);
?>

Alright how serialize works is when you unserialize arrays there already in array form so everytime you add a array like so:

array

(x being the key).

It will either add another key/value or update a key/value of an already existing array.

Now thats the basics on how to update a serialized array in PHP.

Have fun its useful.

If can't view link heres result:

Code:

<?php
$array = serialize(array(1 => "one"));
echo $array;
$array2 = unserialize($array);

$array2[1] = "uno";
$array2[2] = "two";
$arrah = serialize($array2);

echo "<br />".$arrah;

?>

a:1:{i:1;s:3:"one";}
a:2:{i:1;s:3:"uno";i:2;s:3:"two";}
