How to json_decode invalid JSON with apostrophe instead of quotation mark

Viewed 329 times

Sample code:

<?php

$json = "['foo', 'bar']";

var_dump( json_decode($json) );

~~It works with PHP 5.5.3 but it fails for lower PHP's versions~~

It works on my machine with PHP 5.5.3 but it fails everywhere else.

I know it is incorrect JSON but my webservice gives me JSON with ' symbols together with "

['foo', "bar", {'test': "crazy "markup""}]

How to parse JSON data with apostrophes in PHP 5.3? Obviously original JSON I want to parse is more complex.

(I can't upgrade my PHP on production server neither get proper JSON from webservice)

Here's an alternative solution to this problem:

function fixJSON($json) {
    $regex = <<<'REGEX'
~
    "[^"\]*(?:\.|[^"\]*)*"
    (*SKIP)(*F)
  | '([^'\]*(?:\.|[^'\]*)*)'
~x
REGEX;

    return preg_replace_callback($regex, function($matches) {
        return '"' . preg_replace('~\\.(*SKIP)(*F)|"~', '\"', $matches[1]) . '"';
    }, $json);
}

This approach is more robust than h2ooooooo's function in two respects:

It preserves double quotes occurring in a single quoted string, by applying additional escaping to them. h2o's variant will replace them with double quotes instead, thus changing the value of the string.
It will properly handle escaped double quotes ", for which h2o's version seems to go into an infinite loop.

Test:

$brokenJSON = <<<'JSON'
['foo', {"bar": "hel'lo", "foo": 'ba"r ba"z', "baz": "wor"ld ' test"}]
JSON;

$fixedJSON = fixJSON($brokenJSON);
$decoded = json_decode($fixedJSON);

var_dump($fixedJSON);
print_r($decoded);

Output:

string(74) "["foo", {"bar": "hel'lo", "foo": "ba"r ba"z", "baz": "wor"ld ' test"}]"
Array
(
    [0] => foo
    [1] => stdClass Object
        (
            [bar] => hel'lo
            [foo] => ba"r ba"z
            [baz] => wor"ld ' test
        )
)

Try something like this:

//initialize array
$myArray = array();

//set up the nested associative arrays using literal array notation
$firstArray = array("id" => 1, "data" => 45);
$secondArray = array("id" => 3, "data" => 54);

//push items onto main array with bracket notation (this will result in numbered indexes)
$myArray[] = $firstArray;
$myArray[] = $secondArray;

//convert to json
$json = json_encode($myArray);

Here is a complete implementation:

<test-element obj='{"a": 1, "b": 2, "c": 3}'></test-element>

<dom-module id="test-element">
    <template>

        <template is="dom-repeat" items="{{_toArray(obj)}}">
            name: <span>{{item.name}}</span>
            <br> value: <span>{{item.value}}</span>
            <br>
            <hr>
        </template>

    </template>
    <script>
    Polymer({

        properties: {
            obj: Object
        },

        _toArray: function(obj) {
            return Object.keys(obj).map(function(key) {
                return {
                    name: key,
                    value: obj[key]
                };
            });
        }

    });
    </script>

</dom-module>

you can use it like this, in JSON format when you evaluate false value it will give you blank, and when you evaluate true it will give you 1.

$str = '[{"clientId":"17295c59-4373-655a-1141-994aec1779dc","channel":"/meta/connect","connectionType":"long-polling","ext":{"fm.ack":false,"fm.sessionId":"22b0bdcf-4a35-62fc-3764-db4caeece44b"},"id":"5"}]';

$arr = json_decode($str,true);

if($arr[0]['ext']['fm.ack'])    // suggested by **mario**
{
    echo "true";    
}
else {
    echo "false";   
}

Have a look at: http://grails.1312388.n4.nabble.com/The-groovy-truth-of-JSONObject-Null-td3661040.html

Ian Roberts mentions a nice trick to make a null check possible:

JSONObject.NULL.metaClass.asBoolean = {-> false}
