PHP Unserialise Within an Array

Question

I have an array that has the following values

[0] => array(4) {
["sku"] => string(12) "WMS-M-VN-MRN"
["name"] => string(62) "Maroon V-neck Jumper"
["qty_ordered"] => string(6) "1.0000"
["product_options"] => string(533) "a:2:{s:15:"info_buyRequest";a:6:{s:4:"uenc";s:64:"aHR0cDovL2VtYmxlbWF0aWMuY28udWsvd21zLW0tdm4tbXJuLz9fX19TSUQ9VQ,,";s:7:"product";s:3:"780";s:8:"form_key";s:16:"gDXvCEtQOlRWihqc";s:15:"related_product";s:0:"";s:7:"options";a:1:{i:1970;s:5:"17201";}s:3:"qty";s:1:"1";}s:7:"options";a:1:{i:0;a:7:{s:5:"label";s:27:"PLEASE SELECT SIZE REQUIRED";s:5:"value";s:12:"36 inch (13)";s:11:"print_value";s:12:"36 inch (13)";s:9:"option_id";s:4:"1970";s:11:"option_type";s:9:"drop_down";s:12:"option_value";s:5:"17201";s:11:"custom_view";b:0;}}}"
}

Now is there a way to unserialise the "Product_options" field in-line, without having to break the array apart and rebuild it again?

@u_mulder - as in can i unserialise without breaking the array apart in a loop — James Simpson

No. you don't work with the serialized string. If you do something wrong, you've corrupted the ENTIRE string. you unserialize, manipulate the data structure you get from that, then re-serialize. — Marc B

This is the way. You just have to reassign the result of unserialize to the same array item.

<?php

$array = [
    [
        "sku" => "WMS-M-VN-MRN",
        "name" => "Maroon V-neck Jumper",
        "qty_ordered" => "1.0000",
        "product_options" => 'a:2:{s:15:"info_buyRequest";a:6:{s:4:"uenc";s:64:"aHR0cDovL2VtYmxlbWF0aWMuY28udWsvd21zLW0tdm4tbXJuLz9fX19TSUQ9VQ,,";s:7:"product";s:3:"780";s:8:"form_key";s:16:"gDXvCEtQOlRWihqc";s:15:"related_product";s:0:"";s:7:"options";a:1:{i:1970;s:5:"17201";}s:3:"qty";s:1:"1";}s:7:"options";a:1:{i:0;a:7:{s:5:"label";s:27:"PLEASE SELECT SIZE REQUIRED";s:5:"value";s:12:"36 inch (13)";s:11:"print_value";s:12:"36 inch (13)";s:9:"option_id";s:4:"1970";s:11:"option_type";s:9:"drop_down";s:12:"option_value";s:5:"17201";s:11:"custom_view";b:0;}}}'
    ]
];

$array[0]["product_options"] = unserialize($array[0]["product_options"]);

echo "<pre>";
print_r($array);
echo "</pre>";

Output:

Array
(
    [0] => Array
        (
            [sku] => WMS-M-VN-MRN
            [name] => Maroon V-neck Jumper
            [qty_ordered] => 1.0000
            [product_options] => Array
                (
                    [info_buyRequest] => Array
                        (
                            [uenc] => aHR0cDovL2VtYmxlbWF0aWMuY28udWsvd21zLW0tdm4tbXJuLz9fX19TSUQ9VQ,,
                            [product] => 780
                            [form_key] => gDXvCEtQOlRWihqc
                            [related_product] => 
                            [options] => Array
                                (
                                    [1970] => 17201
                                )

                            [qty] => 1
                        )

                    [options] => Array
                        (
                            [0] => Array
                                (
                                    [label] => PLEASE SELECT SIZE REQUIRED
                                    [value] => 36 inch (13)
                                    [print_value] => 36 inch (13)
                                    [option_id] => 1970
                                    [option_type] => drop_down
                                    [option_value] => 17201
                                    [custom_view] => 
                                )

                        )

                )

        )

)

yes this worked, although i had to tweak it a bit as there was more than one entry, but that method worked a charm :) thanks.
