presumed difference in php versions causing difference in JSON output - quotes around integers

I have a testing server with PHP version 5.5.9, and we have a QA server with PHP version 5.6.16.

I am for the sake of this post using the same code branch on both instances (full disclosure: it's a Laravel install but I'm not sure this is a Laravel issue)

On the QA server, an API returns JSON with the integers unquoted as follows (this is simplified):

{["id":1,"name":"John"],["id":2,"name":"Sam"]}

But on my server (the 5.6.16 one), the same exact API call returns:

{["id":"1","name":"John"],["id":"2","name":"Sam"]}

And, Angular is not liking that and does not parse it.

It's not the data

The data and tables the data is coming from are exactly alike in structure - I have verified this.

I don't want to "fix" Angular

Though in theory Angular should handle this(?), I don't want to touch our coding for the front end.

I want the output to be the same..

Regardless of what Angular is doing, the obvious solution is to have the outputs be exactly equal.

What do I do?

As @RiggsFolly it definitely depends on how the source is providing the integer data. If the numbers are quoted from source, json_decoder treats them as a string.

Something you can try: json_encode as a 2nd parameter called $options. Set it to attempt to encode numbers as integers rather than strings.

Its not an issue in json_encode() it is what you are encoding that makes a difference. See this simple example

$a = array(
    'id' => 111,
    'astring' => 'test',
    'OhLookItsANumberRecordedAsAString' => '456'
);
$json = json_encode($a);
echo $json;

Result

{"id":111,
 "astring":"test",
 "OhLookItsANumberRecordedAsAString":"456"
}

But if you make sure the integers are integers all is as you expect

$a = array(
        'id' => 111,
        'astring' => 'test',
        'OhLookItsANumberRecordedAsAString' => '456',
        'ANumber' => (int)'456'
    );
$json = json_encode($a);
echo $json;

Result

{"id":111,
 "astring":"test",
 "OhLookItsANumberRecordedAsAString":"456",
 "ANumber":456
}
