I have written an xml-parser to read an XML-file. The XML-file is not mine so I can't change the structure. Things work great till I got to this special point. I want to read a value but I don't have a key to access this value.
I marked the values (in red) in the screenshot below which I want to access.
When I dump the parent element (the PRAT->VALUE) I get this in return:
object(SimpleXMLElement)#31 (3) { ["#attributes"]=> array(5) { ["nr"]=> string(1) "1" ["unit"]=> string(3) "bar" ["unit_id"]=> string(4) "3103" ["vo"]=> string(0) "" ["vo_id"]=> string(0) "" } [0]=> string(2) "20" [1]=> string(1) "2" }
As seen, at the end of the dump the values that I want to access are presented. I tried to access it like an array but that doesn't work. The values are not part of the attributes.
use (String) keyword in front of it.
eg.
echo (String) PRAT->VALUE;

I have finally managed to retrive data from mongoDB within PHP. How ever I am not able to retrieve single elements from this array looking. I can only vardump() the cursor. How is it possible to print single elements from this array that seems to be made up of objects?
object(stdClass)#11 (7) { ["_id"]=> object(MongoDB\BSON\ObjectID)#9 (1) { ["oid"]=> string(24) "5a4a2cf55ff0f310cbf1c3a4" } ["Category"]=> string(9) "Allgemein" ["DateAdded"]=> object(MongoDB\BSON\UTCDateTime)#10 (1) { ["milliseconds"]=> string(13) "1514810613331" } ["Name"]=> string(4) "Welt" ["Website"]=> string(11) "www.welt.de" ["Active"]=> bool(true) ["Country"]=> string(2) "DE" }
I couldnt find anything on goolgle or PHP/mongodb documentation. Why cant I just do $array["_id"]? And how can I retrieve _id for example?
The resource is an object of stdClass. So you need to use:
echo $array->_id;
In case, if you want to use arrays, use get_object_vars() function. That way:
$array = get_object_vars($array);
echo $array["_id"];
And then you can use objects as arrays.
I have a URL formatted like this:
https://chipperyman.com/commander/codes/check.php?type=check&group=w&cpu=63_char_string&version=27&group=1
However, when I use var_dump($_GET);, the w variable is set to &string(1) => 1. This is the full array:
array(4) { ["type"]=> string(5) "check" ["group"]=> &string(1) "1" ["cpu"]=> string(63) "63_char_string" ["version"]=> string(2) "27" }
Why is $_GET['group'] not outputting correctly? When I try to echo it or use it in anything else (.=, etc) it is not treated as a w.
group=1 overrides group=w since it comes last and you can't have 2 variables with the same name.
It doesn't seem like you want this, but it is possible to have a group array using:
group[]=w&group[]=1
I am trying to decode JSON
I am reading the JSON through STOMP. There are different JSON datasets so I need to work out which JSON dataset has come through. I do this by reading its title.
However there is one particular dataset I am having trouble reading
foreach (json_decode($msg->body,true) as $event) {
if(isset($event['schemaLocation'])) {
$schedule_id=($event['schedule']['schedule_start_date']);
$signalling_id=($event['schedule']['schedule_segment']['signalling_id']);
echo $schedule_id;
}
In the above example the isset function works fine and also $schedule_id obtains the right answer
However the $signalling_id gives an error of Undefined index:
Here is a dump of PART of the JSON (Its rather long............).The piece of JSON with the signalling_id is towards the end of the JSON. Any help to get the variable signalling_id much appreciated.

schedule_segment is itself an array, so instead of
['schedule']['schedule_segment']['signalling_id']);
that should probably be
['schedule']['schedule_segment'][0]['signalling_id']);
As you can see in the var dump, signalling_id is inside another array. Use:
$signalling_id=($event ['schedule']['schedule_segment'][0]['signalling_id']);
If that one element array with key 0 is not constant throughout, you may need some logic to figure out what it is in each iteration.
I hope I can make this question clear enough.
I'm looking to put a list of arrays inside one master array, dynamically, so that it looks like this:
masterarray {
array1
{ [0]=>VAL1 [1]=>VAL2 }
array2
{ [0]=>VAL1 [1]=>VAL2 }
array3
{ [0]=>VAL1 [1]=>VAL2 }
}
I've tried, but I could only get it to look like this:
array(1) { [0]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } }
array(2) { [0]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } [1]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } }
array(3) { [0]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } [1]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } [2]=> array(2) { [0]=> string(1) "1" [1]=> string(13) "CODE" } }
And that's definitely not what I'm aiming for. Nothing seems contained. I need the format specified above.
I'm using the explode function on a string pulled from a file to make this table of arrays (I think you call it that)
Here is the code I'm using that's not working.
$variabledebugging = file("FILE.TXT");//LOOK IN THIS FILE FOR THE NUMBER AND SET IT TO A VAR.
$i=0;
foreach($variabledebugging as $placeholder){
$variabledebuggingtbl[] = explode("\t",$variabledebugging[$i]);
var_dump($variabledebuggingtbl);
$i++;
}
I've tried a couple of different variations, but that's the one I'm using now.
To be clear, that file being pulled (each line as a value in an array) has 2 things written to each line, separated by a tab character, so that's the system I'm going on.
Thank you! I'm sure this is a simple task, I just can't think it through.
Oh and while I'm at is there a way to make debugging more readable?
You ARE getting the right result. The reason it seems wrong is that you are running var_dump inside the loop. And why don't you use the $placeholder variable?
$variabledebugging = file("FILE.TXT");
foreach($variabledebugging as $placeholder){
$variabledebuggingtbl[] = explode("\t", $placeholder);
}
var_dump($variabledebuggingtbl);
I'm not sure what you mean by "making debugging more readable", but if you want some linebreaks and indentation you should just look in the generated HTML code. var_dump do add spacing to make it readable but it is ignored by the web browser. If you don't want to read the HTML source, just add your var_dump to a <pre> element.
I have the following already decoded json stored in $response = $result->response;:
object(stdClass)#6 (5) {
["EmailAddress"]=> string(18) "email#gmail.com"
["Name"]=> string(0) ""
["Date"]=> string(19) "2011-10-09 19:32:00"
["State"]=> string(6) "Active"
["CustomFields"]=> array(1) {
[0]=>object(stdClass)#7 (2) {
["Key"]=>string(2) "id"
["Value"]=>string(6) "Dl9lIz"
}
}
I can already access the main attributes (EmailAddress, Name, etc) with:
$email = $response->{'EmailAddress'};
print $email;
But I need to access the "Value" portion in the CustomFields object. I don't know how to dig that deep. I'm attempting to do this in PHP..
Any suggestions?
It is contained in the first element ([0]) of array CustomFields, so you can access it with an object operator (->) after the array index.
print $response->CustomFields[0]->Value;
