I'm getting a PHP array from a web page (as a string).
It looks like :
Array
(
[k1] => Array
(
[a] => Array
(
[id] => 1
[age] => 60
)
[b] => Array
(
[id] => 2
[age] => 30
)
)
[k2] => v2
)
I want to parse it in python.
Does anyone have an idea how to do this?
Thanks,
Rivka
Edit:
This is really not a json, like a few people commented.
Thanks for the comments, and I updated the question.
That's not JSON, that's just how PHP prints arrays. If you want to create JSON of the array, check out json_encode for PHP. Then use Python's JSON library (or here for py3) to read it.
If I understood you correctly, you are using print_r on array to get that output. This is a visual representation of array only, you can't really parse it. For example:
array('Array'.PHP_EOL."\t(".PHP_EOL." [0] => test".PHP_EOL."\t)")
will look exactly like
array(array('test'));
You should use some real serializing function to do what you want(json,serialize etc.);

I have an array such as:
$var = array('hi','ho',rand(2,5));
What I would like to echo is the entire array, exactly as written.
Normally when you try a print_r, it shows as:
Array (
[0] => hi
[1] => ho
[2] => 3
)
But I want:
Array (
[0] => hi
[1] => ho
[2] => rand(2,5)
)
You can get this with file_get_contents, but is there any way to do so within the actual PHP file?
I don't think it's possible because when array is created, random value is assigned to element with index 2 and you cannot check how this value was created.
I don't think it's possible, since the rand is already evaluated as soon as you set the array to some variable.
A workaround would be the hold the expression as a string and then eval it when you need it. Like this:
$varStr = "array('hi','ho',rand(2,5))";
echo $varStr;
// when you actually need it
$var = eval($varStr);
However, this is almost never a good idea. Providing a use-case where you need this might help come up with a better solution.
Here is the result on the page when using print_r($result);
Array
(
[result] => Array
(
[0] => Array
(
[username] => Elvis
)
)
)
I would like to pull this out of the array and use it as a PHP variable. I have tried extract, while loops and a variety of other solutions, but I am not finding the right syntax to make this happen. What is the easiest way? Thanks.
Try:
$var = $result['result'][0]['username'];
If the array is consistent, just like you showed it, then you just need
$username=$result['result'][0]['username'];
I am trying to convert indexed array to normal array. Basically what get is:
Array ( [0] => 14 [1] => 19 [2] => 20 )
And I need is:
Array(14,19,20);
I tried over Google but not information found. I think this kind of function isn't available in PHP, is there any? please let me know!
Thanks,
Asif
You're chasing shadows:
Both of the arrays you've shown are equal.
There is no such thing as an unindexed array in PHP.
But if you really want to be sure, use $newArray = array_values($array)
I'm trying to access part of an StdClass that has a property #text. PHP uses '#' for comments so I'm having trouble getting PHP to parse it not as a comment. An example of the StdClass is below
stdClass Object
(
[artist] => stdClass Object
(
[name] => John Denver
[mbid] => 34e10b51-b5c6-4bc1-b70e-f05f141eda1e
[url] => http://www.last.fm/music/John+Denver
[image] => Array
(
[0] => stdClass Object
(
[#text] => http://userserve-ak.last.fm/serve/34/521025.jpg
[size] => small
and I've tried to access it with:
$json->artist->image[0]->#text
but how can I escape the '#' or tell php to interpret it differently. Or is there another format to find the #text property.
I also tried:
$json['artist']['image'][0]['#text']
but I get an error. I'm sure this is something simple but it's really got me at the moment.
You can access such properties with the following code:
$object->{'#text'}
It seems to be JSON data, so when decoding, you can also set the second parameter to true:
$json = json_decode($input, true);
Now you are able to use this:
$json['artist']['image'][0]['#text']
Citing another answer you can put the key in a variable an accessing it via this variable.
$var='myvarwithstrangecharacters$asdfas#';
$object->$var;//do whatever you want

How do I access a PHP object attribute having a dollar sign?
I'm probably missing something quite basic, but I'm getting very confused (and frustrated) with the results I get from my SOQL queries to the Salesforce API.
My query:
Select Id, FirstName, LastName FROM contact
The resulting object (as rendered by print_r):
stdClass Object
(
[done] => 1
[queryLocator] =>
[records] => Array
(
[0] => stdClass Object
(
[type] => Contact
[Id] => Array
(
[0] => 0032000000cPd7uAAC
[1] => 0032000000cPd7uAAC
)
[any] => BuzzAldrin
)
[1] => stdClass Object
(
[type] => Contact
[Id] => Array
(
[0] => 0032000000cPt1zABC
[1] => 0032000000cPt1zABC
)
[any] => RonnieVanZant
)
[2] => stdClass Object
(
[type] => Contact
[Id] => Array
(
[0] => 0032000000cPb60AA
[1] => 0032000000cPb60AA
)
[any] => PollyJeanHarvey
)
)
[size] => 3
)
The first thing I don't get is why "Id" is an array. A strange quirk, but a workaround is not too hard.
The second thing bothers me endlessly more, though: I select for FirstName and LastName and what happens is they get concatenated and returned as a single string value for a field called "any". To avoid the "split it on uppercase letters" advice I already got from my colleagues, I provided an example with both a two-capital first name and a two-capital last name, and anyhow, in reality I need many more (and more formally unpredictable) fields, and they all get added to this "any" property.
Does anyone see what I'm doing wrong? Assuming it's not such a badly written API, that is?
Edit:
Said developer will now go sit in a corner for a few hours, repenting for not having checked for more recent versions of PHP Toolkit. Seems I was using 11.0, whereas there's already a version 20.0. Shame on me, shame on me indeed. Sorry for wasting your time.
The behavior you are seeing is mostly because of how PHP's SoapClient interprets the results from the API. If you call getLastResponse() on your API connection after you make the query() calls above, you'll see what the actual SOAP messages look like coming back from Salesforce.
As far as the Id array -- its not really an array, but it is listed twice per record (once for the record itself and once as a field), but PHP turns it into an array because it sees it twice. As far as the any, that's happening because PHP is not understanding the namespaced field tags correctly.
As it looks like you found, using the PHP Toolkit can help with these oddities and return sensible objects for you to work with. You might also want to consider looking at Salesforce's REST API, whose results can be directly consumed by json_decode(). For making the HTTP calls to Salesfore, you might be interested in this simple (almost standalone) REST client in a project of mine.
