I am trying to write a soap parameter in REALbasic.
I need to add an array within another array similar to this in php:
$params = array(array(
'sku' => 'some sku'
));
so I can pass this:
$result = $client->call($session, 'catalog_product.list', $params);
I have
dim aArgs (0,1) as String
dim aParmas (0,1) as String
aArgs(0,0)="sku"
aArgs(0,1)="some sku"
aParmas(0,1)= aArgs
But receive a "Type mismatch error. Expected String, but got String(,)"
How can I do this.
Thanks
First off, the line
aParmas(0,1)= aArgs
is wrong because you assign an array (which is in aArgs) to a single element of aParmas. And since those single elements hold a String, you try to assign an array to a single string here, hence the error message.
But I think you're looking at this from the wrong end. You need to start with figuring out what parameters you need to send to the session function you want to call.
That means: You need to find the REALbasic function for $client->call. Once you know which function that is, look at the parameters that function expects. I doubt it expects a two-dimensional array for the "params". Once you know what to pass here, let us know if you still cannot figure out how to get it working.
An explanation of multidimensional arrays in REALbasic is here
The short answer is that you can't have a PHP-like array of arrays. You need to wrap your array in a class and make the class behave like an array.
Any reason you're using REALbasic? If it's cross-platform you're after, python is ALWAYS a better choice

I have a string of data formatted like so:
[{"pr_a_w":"10","pr_a_we":"10","pr_c_w":"10","pr_c_we":"10"},{"pr_a_w":"20","pr_a_we":"20","pr_c_w":"20","pr_c_we":"20"},{"pr_a_w":"111","pr_a_we":"11","pr_c_w":"111","pr_c_we":"111"}]
The string doesn't have any index/numbers like a regular array would and I'm finding it difficult to extract individual values e.g. with a regular array I could use:
$string[0]["pr_a_w"]
To get the first instance of "pr_a_w" and I could use:
$string[1]["pr_a_w"]
To get the second instance etc.
Is it possible to get single values from this string based on their number?
What you have there is valid JSON (serialized array of objects), so you could use json_decode to translate the serialized data into a native PHP array:
$array = json_decode('[{"pr_a_w":"10","pr_a_we":"10","pr_c_w":"10","pr_c_we":"10"},{"pr_a_w":"20","pr_a_we":"20","pr_c_w":"20","pr_c_we":"20"},{"pr_a_w":"111","pr_a_we":"11","pr_c_w":"111","pr_c_we":"111"}]',true);
$array will then allow you to do exactly what you stated you'd like to do above.
$array[0]["pr_a_w"]; // will give you 10
$array[1]["pr_a_w"]; // will give you 10
Try like this, No need to access with array index. You will get error if you access wrong index.
$json_arr= json_decode('[{"pr_a_w":"10","pr_a_we":"10","pr_c_w":"10","pr_c_we":"10"},{"pr_a_w":"20","pr_a_we":"20","pr_c_w":"20","pr_c_we":"20"},{"pr_a_w":"111","pr_a_we":"11","pr_c_w":"111","pr_c_we":"111"}]',true);
foreach($json_arr as $row){
echo $row['pr_a_w']."<br>";
}
Welcome Stackoverflow nation ! I'm trying to decode json encoded string into SQL statement withing php.
Lets say I've such a json encoded string =>
$j = '{"groupOp":"AND","rules":[{"field":"id","op":"cn","data":"A"},{"field":"i_name","op":"cn","data":"B"}]}';
I want to build SQL WHERE clause (needed for filterToolbar search in jqGrid), something like this => "WHERE id LIKE %A% AND i_name LIKE %B% " and etc.
I've done this =>
$d = json_decode($j);
$filterArray = get_object_vars($d); // makes array
foreach($filterArray as $m_arr_name => $m_arr_key){
// here I can't made up my mind how to continue build SQL statement which I've mentioned above
}
Any ideas how to do that , thanks preliminarily :)
The first problem is you will want to pull out the groupOp operator.
Then, you have an object and inside that you have an array of objects, so you may want to look at the results of filterArray as that won't have the value you want.
Then, when you loop through, you will want to do it with an index so you can just pull the values out in order.
You may want to look at this question to see how you can get data out of the array:
json decode in php
And here is another question that may be helpful for you:
How to decode a JSON String with several objects in PHP?
There is an answer with an implementation for the server-side php code here
Correction: I had to unescape double-quotes in the 'filters' parameter to get it working:
$filters = str_replace('\"','"' ,$_POST['filters']);
(NOTE: This is a follow up to a previous question, How to pass an array within a query string?, where I asked about standard methods for passing arrays within query strings.)
I now have some PHP code that needs to consume the said query string- What kind of query string array formats does PHP recognize, and do I have to do anything special to retrieve the array?
The following doesn't seem to work:
Query string:
?formparts=[a,b,c]
PHP:
$myarray = $_GET["formparts"];
echo gettype($myarray)
result:
string
Your query string should rather look like this:
?formparts[]=a&formparts[]=b&formparts[]=c
If you're dealing with a query string, you are looking at the $_GET variable. This will contain everything after the ? in your previous question.
So what you will have to do is pretty much the opposite of the other question.
$products = array();
// ... Add some checking of $_GET to make sure it is sane
....
// then assign..
$products = explode(',', $_GET['pname']);
and so on for each variable. I must give you a full warning here, you MUST check what comes through the $_GET variable to make sure it is sane. Otherwise you risk having your site compromised.
i have an simple array:
array
0 => string 'Kum' (length=3)
1 => string 'Kumpel' (length=6)
when I encode the array using json_encode(), i get following:
["Kum","Kumpel"]
My question is, what is the reason to get ["Kum","Kumpel"] instead of { "0" : "Kum", "1" : "Kumpel" }?
"{}" brackets specify an object and "[]" are used for arrays according to JSON specification. Arrays don't have enumeration, if you look at it from memory allocation perspective. It's just data followed by more data, objects from other hand have properties with names and the data is assigned to the properties, therefore to encode such object you must also pass the correct property names. But for array you don't need to specify the indexes, because they always will be 0..n, where n is the length of the array - 1, the only thing that matters is the order of data.
$array = array("a","b","c");
json_encode($array); // ["a","b","c"]
json_encode($array, JSON_FORCE_OBJECT); // {"0":"a", "1":"b","2":"c"}
The reason why JSON_FORCE_OBJECT foces it to use "0,1,2" is because to assign data to obeject you must assign it to a property, since no property names are given by developer (only the data) the encoder uses array indexes as property names, because those are the only names which would make sense.
Note: according to PHP manual the options parameters are only available from PHP 5.3.
For older PHP versions refer to chelmertz's answer for a way to make json_encode to use indexes.
As Gumbo said, on the JS-side it won't matter. To force PHP into it, try this:
$a = new stdClass();
$a->{0} = "Kum";
$a->{1} = "Kumpel";
echo json_encode($a);
Not that usable, I'd stick with the array notation.
Just cast as an object and it will work fine...the JSON_FORCE_OBJECT parameter does exactly the same thing.
json_encode((object)$array);
Don't forget to convert it back into a php array so you can access its values in php:
$array = (object)$array;
$array = (array)$array;
json_encode($array);
Since you’re having a PHP array with just numeric keys, there is no need to use a JavaScript object. But if you need one, try Maiku Mori’s suggestion.
I personally think this is a bug that needs to be fixed in PHP. JSON_FORCE_OBJECT is absolutely not an answer. If you try to do any sort of generic programming you get tripped up constantly. For example, the following is valid PHP:
array("0" => array(0,1,2,3), "1" => array(4,5,6,7));
And should be converted to
{"0": [0,1,2,3], "1": [4,5,6,7]}
Yet PHP expects me to either accept
[[0,1,2,3],[4,5,6,7]]
or
{"0":{"0":1,"1":1,"2":2,"3":3},"1":{"0":4,"1":5,"2":6,"3":7}}
Neither of which are right at all. How can I possibly decode an object like that? What possible reason is there to ever change something that is clearly using strings as indexes? It's like PHP was trying to be clever to help out idiotic people who can't differentiate strings from ints, but in the process messed up anyone legitimately using strings as indexes, regardless of what the value COULD be turned into.
You can pass a boolean to json_decode to return an array instead of an object
json_decode('{"foo", "bar", "baz"}', true); // array(0 => 'foo', 1 => 'bar', 2 => 'baz')
My question is this. When parsing object literals, does this guarantee that the ordering of the items will be preserved? I know JSON object properties aren't ordered, but PHP arrays are. I can't find anywhere in the PHP manual where this is addressed explicitly. It probably pays to err on the side of caution, but I would like to avoid including some kind of "index" sub-property if possible.
Wouldn't it make more sense in this case to use an array when you pass the JSON to PHP. If you don't have any object keys in the JSON (which become associative array keys in PHP), just send it as an array. That way you will be guaranteed they will be in the same order in PHP as in javascript.
json_decode('{["foo", "bar", "baz"]}');
json_decode('["foo", "bar", "baz"]'); //I think this would work
If you need associative arrays (which is why you are passing the second argument as true), you will have to come up with some way to maintain their order when passing. You will pry have to do some post-processing on the resulting array after you decode it to format it how you want it.
$json = '{[ {"key" : "val"}, {"key" : "val"} ]}';
json_decode($json, true);
Personally, I've never trusted any system to return an exact order unless that order is specifically defined. If you really need an order, then use a dictionary aka 2dimension array and assigned a place value (0,1,2,3...) to each value in the list.
If you apply this rule to everything, you'll never have to worry about the delivery/storage of that array, be it XML, JSON or a database.
Remember, just because something happens to work a certain way, doesn't mean it does so intentionally. It's akin to thinking rows in a database have an order, when in fact they don't unless you use an ORDER BY clause. It's unsafe to think ID 1 always comes before ID 2 in a SELECT.
I've used json_decode() some times, and the results order was kept intact with PHP client apps. But with Python for instance it does not preserve the order.
One way to be reassured is to test it over with multiple examples.
Lacking an explicit statement I'd say, by definition, no explicit order will be preserved.
My primary line of thought it what order, exactly, would this be preserving? The json_decode function takes a string representation of a javascript object literal as it's argument, and then returns either an object or an array. The function's input (object literal as string) has no explicit ordering, which means there's no clear order for the json_decode function to maintain.
