json_decode variables php - php

I'm simply trying to extract variables from a json_decode
the resulting decoded code (a snippet of) is:
auth_info:
array(4) {
["profile"]=>
array(13) {
["name"]=>
array(3) {
["givenName"]=>
string(6) "John"
["familyName"]=>
string(7) "Doe"
["formatted"]=>
string(14) "John Doe"
}
}
}
I'm trying all things such as:
echo "\n\nMy name is ".$auth_info['profile']->name->givenName;
But all to no avail..ideas please?
Many thanks as always
Darren

They are all arrays, try this.
$auth_info['profile']['name']['givenName']

PHP get specific value of a specific key in a multidimensional array

Say I have the following array (this comes from a var_dump):
($defaults = )array(3) {
["sitewide_typography_title"]=>
array(2) {
["font-family"]=>
string(16) "Playfair Display"
["variant"]=>
string(7) "regular"
}
["sitewide_typography_text"]=>
array(2) {
["font-family"]=>
string(6) "Roboto"
["variant"]=>
string(3) "300"
}
["sitewide_typography_btn"]=>
array(2) {
["font-family"]=>
string(6) "Roboto"
["variant"]=>
string(3) "300"
}
}
I guess this is an easy question, but I really can't find the answer. I think my googling skills failed me in this, but how do I get the font-family value for sitewide_typography_title?
Thanks a lot in advance!
It's simple
$defaults['sitewide_typography_title']['font-family'];
To echo it out like this
echo $defaults['sitewide_typography_title']['font-family'];
Should output
Playfair Display

(PHP) var_dumping an object in structured format.

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.

Decoding Particular Element of JSON In PHP

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.
array(7) {
["schemaLocation"]=>
string(72) "http://xml.networkrail.co.uk/ns/2008/Train itm_vstp_cif_messaging_v1.xsd"
["classification"]=>
string(8) "industry"
["timestamp"]=>
string(13) "1410374918000"
["owner"]=>
string(12) "Network Rail"
["originMsgId"]=>
string(47) "2014-09-10T18:48:38-00:00vstp.networkrail.co.uk"
["Sender"]=>
array(3) {
["organisation"]=>
string(12) "Network Rail"
["application"]=>
string(4) "TOPS"
["component"]=>
string(4) "VSTP"
}
["schedule"]=>
array(11) {
["schedule_id"]=>
string(0) ""
["transaction_type"]=>
string(6) "Create"
["schedule_start_date"]=>
string(10) "2014-09-10"
["schedule_end_date"]=>
string(10) "2014-09-10"
["schedule_days_runs"]=>
string(7) "0010000"
["applicable_timetable"]=>
string(1) "N"
["CIF_bank_holiday_running"]=>
string(1) " "
["CIF_train_uid"]=>
string(6) "W64017"
["train_status"]=>
string(1) "1"
["CIF_stp_indicator"]=>
string(1) "O"
["schedule_segment"]=>
array(1) {
[0]=>
array(20) {
["signalling_id"]=>
string(4) "5Y75"
["uic_code"]=>
string(0) ""
["atoc_code"]=>
string(0) ""
["CIF_train_category"]=>
string(2) "EE"
["CIF_headcode"]=>
string(0) ""
["CIF_course_indicator"]=
............................................
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.

PHP Retrieving data values from foreach on sub arrays

I'm trying to get the values of a sub array out in a foreach loop.
I looked at this example as it seemed really relevant to my problem, but unfortunately I've not been able to get it to work, and I'm hoping someone here can pick up where I've gone wrong.
PHP foreach not working with sub-array
I have an array called $booked and inside that array I have a sub array $booked['30_booked'].
Within that second array there are multiple values, such as title, name, address etc.
My code currently looks like this:
foreach($booked['30_booking'] as $new_var){
var_dump('</br>', $booked['30_booking']);
var_dump('</br>', $new_var);
var_dump($new_var['title'], $new_var->title, $booked['30_booking']->title); exit();
}
I've output the data as you can see above in var_dump statements to try and get one of these methods to work.
Unfortunately nothing within $new_var is pulling out the title, but $booked['30_booking']->title
Have I not put it into the foreach statement correctly?
All help appreciated - thanks!
EDIT:
Main array output snippet:
array(6) { ["30_booked"]=> object(stdClass)#21 (34) { ["id"]=> string(2) "30" ["title"]=> string(2) "Ms" ["firstname"]=> string(5) "FIRST NAME" ["surname"]=> string(9) "LAST NAME" ["address"]=> string(6) "- -- -" ["postcode"]=> string(7) "FAK E99" ["country"]=> string(14) "United Kingdom" ["phone"]=> string(11) "01221111111" ["alt_phone"]=> string(0) "" ["email"]=> string(25) "fake#fake.co.uk" ["notes"]=> string(8) "FAKE DEAL" } }
EDIT 2:
Sub Array $booked['30_booking'] snippet:
object(stdClass)#21 (34) { ["id"]=> string(2) "30" ["title"]=> string(2) "Ms" ["firstname"]=> string(5) "FIRST NAME" ["surname"]=> string(9) "LAST NAME" ["address"]=> string(6) "- -- -" ["postcode"]=> string(7) "FAK E99" ["country"]=> string(14) "United Kingdom" ["phone"]=> string(11) "01221111111" ["alt_phone"]=> string(0) "" ["email"]=> string(25) "fake#fake.co.uk" ["notes"]=> string(8) "FAKE DEAL" }
EDIT 3:
My var_dump of the $new_var by itself is bringing back the value of the id - but when I try and get the second value out the sub array "title" it doesn't return anything.
FINAL FIX:
Thanks to Kita I realised I was returning a std class object and not a second array, something that I stupidly missed the first time round. Because of that I can't actually foreach on the object.
Which led me to this post which will help me fix the issue:
PHP foreach array with stdClass Object
Thank you very much for all your help!!!
You expected an array inside $booked['30_booking'] but in fact there was a stdClass object.
array(6) {
["30_booked"]=> object(stdClass)#21 (34) {
["id"]=> string(2) "30"
["title"]=> string(2) "Ms"
["firstname"]=> string(5) "FIRST NAME"
["surname"]=> string(9) "LAST NAME"
["address"]=> string(6) "- -- -"
["postcode"]=> string(7) "FAK E99"
["country"]=> string(14) "United Kingdom"
["phone"]=> string(11) "01221111111"
["alt_phone"]=> string(0) ""
["email"]=> string(25) "fake#fake.co.uk"
["notes"]=> string(8) "FAKE DEAL"
}
//I assume you have left out the other array elements from the Main array snippet.
}
Getting stdClass instead of array usually happens when you parse a JSON string with json_decode() without the second parameter.
// without second parameter
var_dump( json_decode( '{"id":"30"}' ) );
object(stdClass)#1 (1) {
["id"]=>
string(2) "30"
}
// 'true' as second parameter
var_dump( json_decode( '{"id":"30"}', true ) );
array(1) {
["id"]=>
string(2) "30"
}
Above examples are hosted at: http://ideone.com/GNMRlD
Since stdClass object itself does not provide iteration functionality, using it with foreach will yield errors.
You can convert stdClass into array with functions such as http://www.if-not-true-then-false.com/2009/php-tip-convert-stdclass-object-to-multidimensional-array-and-convert-multidimensional-array-to-stdclass-object/ .
For eg. if your array looks like below. foreach which I used will be working
$new_array = array(array('total'=>array('title'=>'test','text'=>'text')));
foreach ($new_array as $val)
{
print_r($val['total']['title']); // Use this for array
print_r($val->total->title); // Use this for object
}
if your array looks like below. Use the below foreach.
$new_array = array(array('total'=>array(array('title'=>'test','text'=>'text'),array('title'=>'test1','text'=>'text1'))));
foreach ($new_array as $val)
{
foreach($val['total'] as $new_val)
{
print_r($new_val['title']);
}
}
You can try this, I hope that helps you
foreach($booked as $new_var){
var_dump('</br>', $new_var);
var_dump('</br>',$new_var['30_booking']->title);
}
I think in your foreach there is mistake of word 30_booking
since in your main array out put display it shows 30_booked
check that also

A list of arrays contained in a master array PHP

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.
