I got the following results in a object after I did a var_dump on that object, how can I access the individual elements and put them into a variable?
I tried:
$content["ID"];
$content->ID;
but no result :-(
["ID"]=>
string(5) "31655"
["Reference"]=>
string(7) "1899801"
["FullName"]=>
string(18) "Lennie De Villiers"
["Username"]=>
string(12) "lenniedg2000"
Try it on your end and see output
echo $content->ID;
$var=$content->ID;
echo $var;
Just take a look here I created an example

I need to analyze an object in my code, but when I do a var_dump (or print_r) it just prints the object out with no structure, for example:
[0]=> object(simple_html_dom_node)#2185 (9) { ["nodetype"]=> int(1) ["tag"]=> string(3) "div" ["attr"]=> array(1) { ["class"]=> string(36) "element element--collection internal" } ["children"]=> array(2) { [0]=> object(simple_html_dom_node)#2187 (
I need to see it in a more structured format so I can see what is going on, i.e.:
object(simple_html_dom_node)#2185 (9) {
["nodetype"]=> int(1)
["tag"]=> string(3) "div"
["attr"]=> array(1)
{
["class"]=> string(36) "element element--collection internal"
}
["children"]=> array(2) {
[0]=> object(simple_html_dom_node)#2187 (9)
Does anyone know how to do this?
The format you want is actually how var_dump() prints the object. The problem is that you're doing it in an HTML document, and the browser reformats it.
If you put it inside a <pre> tag, the browser will leave the formatting alone. So:
echo "<pre>"; var_dump($object); echo "</pre>";
Try using var_export(), this function will give you a more readable structure of the object or data.
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 $array["_id"];
And then you can use objects as arrays.
Hello awesome programmers!
I am so sorry for the the novice question, however, I am having trouble finding a solution to my problem. I am attempting to run a for each loop through my array passed from my controller, however, the data being outputted is not the same as when I run a var_dump($array). I am thinking perhaps that I need to iterate through this object maybe? However, when I attempt to do so, I get a non-object error.
Controller:
$data['user_details'] = $this->ion_auth->user()->row();
View:
var_dump($user_details);
foreach($user_details as $item){
echo $item['email'];
}
The output of this is : "21nfn4111NR12" but should be roger#peterson.net!
I have also tried the object form:
var_dump($user_details);
foreach($user_details as $item){
echo $item->email;
}
However, it results in error trying to get property of non-object!
When I run the var dump I get the following:
object(stdClass)#21 (17) {
["id"]=>
string(1) "2"
["ip_address"]=>
string(14) "119.132.127.01"
["username"]=>
string(12) "roger petereson"
["password"]=>
string(40) "fdZxF/RQo4nZKmbA5XQlwefbc8f8e5c74899c3d0"
["salt"]=>
NULL
["email"]=>
string(19) "roger#peterson.net"
["activation_code"]=>
NULL
["forgotten_password_code"]=>
NULL
["forgotten_password_time"]=>
NULL
["remember_code"]=>
string(22) "44hjOlloLTIrkSrjSBVNie"
["created_on"]=>
string(10) "1404939094"
["last_login"]=>
string(10) "1405099607"
["active"]=>
string(1) "1"
["first_name"]=>
string(6) "Roger"
["last_name"]=>
string(5) "Peterson"
["is_owner"]=>
string(1) "1"
["user_id"]=>
string(1) "2"
}
The following line:
$this->ion_auth->user()->row();
returns an object not an array (check your var_dump output), so you just need to
echo $user_details->email;
I have been trying to figure this out for a while now. Please any advice would be appreciated. I just need to access the array for ["Item"]. How do I gain access to this?
array(1) {
[0]=>
object(SimpleXMLElement)#16 (2) {
["#attributes"]=>
array(2) {
["Name"]=>
string(10) "AuthorList"
["Type"]=>
string(4) "List"
}
["Item"]=>
array(3) {
[0]=>
string(9) "Smith, Joe"
[1]=>
string(10) "Peter, Ann"
[2]=>
string(18) "Magoo, Mr"
}
}
}
Assuming this structure is in a variable called var1, you should be able to access Item using:
$var1[0]->Item // returns the array
I try to explain it.
Like you see, your first array index is an object.
If you see something like this in your var_dump than you can access it through deferencing the object.
It's the same like you would create an object and would like to access a public variable:
$var1 = new Object();
// when your Object variables are public so you could access them by deference the Object
echo $var1->myVariable; // will echo the public variable "myVariable"
So the answer from adam is the right one :)
I think I am either just stupid or something but I still can't get my head around them.
I am trying to access "patient_age" from this variable $result.
Here is the var dump.
array(1) {
["intervention"]=>
array(1) {
[0]=>
object(stdClass)#23 (21) {
["intervention_id"]=>
string(1) "1"
["patient_id"]=>
string(1) "1"
["name_id"]=>
string(1) "1"
["department_id"]=>
string(1) "1"
["dosage_id"]=>
NULL
["edocument"]=>
string(10) "Bruce1.jpg"
["user_id"]=>
string(1) "0"
["duration"]=>
string(8) "02:26:00"
["submitted"]=>
string(19) "2011-07-31 19:56:29"
["intervention_comment"]=>
NULL
["patient_age"]=>
string(2) "34"
["patient_height"]=>
string(4) "1.34"
["patient_weight"]=>
string(2) "45"
["patient_gender"]=>
string(4) "Male"
["department_name"]=>
string(10) "Cardiology"
["intervention_name_id"]=>
string(1) "1"
["intervention_name"]=>
string(5) "IVH 2"
["intervention_description"]=>
string(0) ""
["dosage_emitted"]=>
NULL
["dosage_absorbed"]=>
NULL
["dosage_period"]=>
NULL
}
}
}
I have tried :
$result[0]->patient_age;
$result[1]->patient_age;
$result['intervention']->patient_age;
$result['intervention'][0]->patient_age;
Hopefully someone could give me the answer but also explain how they came to this answer as all the other Stackoverflow questions they just give the solution but not the method.
Anyone got any tips how to navigate nested variables.
Thanks
$object=$result['intervention'][0];
print $object->patient_age;
Check if any other variables are accessable
It should be your last example. It's not that hard, really. $result is an array which contains a single element, with the key "intervention". You can access an array's elements by using [ and ]. So, with $result['intervention'], you get an array that also contains a single element: the element at key 0, which is an instance of stdClass. You can reach that by using $result['intervention'][0]. If you want to get the patient_age from that stdClass, you can access the instance variables with the ->. So, this should work:
echo $result['intervention'][0]->patient_age;
The following would result in $patient being the stdClass instance, which you can then retrieve patient_age from:
$patient = $result['intervention'][0];
echo $patient->patient_age;
$result[0]->patient_age;
will work *as long as patient_age is a public variable*. If it's private or protected you'll need to use a method within the object to access it.
You never said what happened with the stuff you tried. Null values? Error/warning messages?
Proof:
<?php
class iv {
var $patient_age;
function __construct($val)
{
$this->patient_age=$val;
}
}
$t=new iv(40);
$result=array(0=>$t);
var_dump($result) . "\n\n";
print "val = " . $result[0]->patient_age . "\n\n";
[user#example ~]$ php -q t.php
array(1) {
[0]=>
object(iv)#1 (1) {
["patient_age"]=>
int(40)
}
}
val = 40
[user#example ~]$
