Php unserialize string

Question

When I do var_dump($string); I get

string(894) "[{"id":"11","value":"Gotowy do u\u017cytku"},{"id":"12","value":"Na 4 k\u00f3\u0142kach"},{"id":"13","value":"20 minut - rozgrzany do pracy"},{"id":"14","value":"Pow. u\u017cytkowa 108 cm2"},{"id":"15","value":"Piec i grill w jednym"},{"id":"16","value":["tekst","\/images\/alfa\/domowa\/forninox\/1.jpg","lightbox"]},{"id":"17","value":["tekst","\/images\/alfa\/domowa\/forninox\/1.jpg","lightbox"]},{"id":"18","value":["tekst","\/images\/alfa\/domowa\/forninox\/3.jpg","lightbox"]},{"id":"19","value":["tekst","\/images\/alfa\/domowa\/forninox\/2.jpg","lightbox"]},{"id":"20","value":"cm 127"},{"id":"21","value":"cm 189"},{"id":"22","value":"cm2 108"},{"id":"23","value":"Kg 340"},{"id":"24","value":"\u00a6 cm 25\/20"},{"id":"25","value":"Mat. ceramiczny"},{"id":"26","value":"Stal nierdzewna"},{"id":"27","value":"W\u0142. ceramiczne"},{"id":"28","value":"min 20"},{"id":"29","value":"7"}]"

and I what to put this string into array, so I do unserialize, like this:

$a = unserialize($string); 
var_dump($a);

But in the output I get:

bool(false)

Enybody knows what I'm doing wrong?

You've got a json string. You want to use

$arr = json_decode($string, TRUE);

to deserialize it to an associative array.

Thank you very much, how did you recognize that is a json string?

Note this would not deserialize into an associate array, but rather a numerically indexed array. JSON has no concept of an associative array.

@MikeBrant php does have a concept of an associative array, though. If he used this solution, he could reference "tekst" by using $arr[5]["value"][0]. This key,value, dictionary-type referencing is the same as a php associative array.

@MikeBrant Here is the php reference to json_decode php.net/manual/en/function.json-decode.php

Mike Brant Over a year ago

Yes, but truly this is a numerically indexed array of objects. The main enclosing array is a numerically indexed array not an associative array. You also cannot use ArrayAccess on the stdClass object that would be created for each value in the array. So your example would have to be $arr[5]->value[0]

It's not serialized, but json encoded. Use:

$decoded = json_decode($string);
