Foreach creating multi-level instead of single level array in PHP - php

I'm trying to gather a group of term_id's output in a foreach and create an array from them. I then want to update the taxonomy with the values in the array however the array is being created as multi-level. My code is as follows:
$updateTax = array();
foreach ($featuresArray as $key => $value) {
if ($key = 'en_value') {
$termResult = get_term_by('name', $value['en_value'], $taxonomy);
$term = $termResult->term_id;
$updateTax[] = array($term);
}
}
...which then gives this output:
var_dump($updateTax);
array(29) {
[0]=> array(1) {
[0]=> int(111) } [1]=> array(1) {
[0]=> int(116) } [2]=> array(1) {
[0]=> int(124) } [3]=> array(1) {
...
[0]=> int(408) } [25]=> array(1) {
[0]=> int(447) } [26]=> array(1) {
[0]=> int(520) } [27]=> array(1) {
[0]=> int(593) } [28]=> array(1) {
[0]=> int(628) }
}
...but I was expecting the following:
array(29) {
[0]=> int(111) }
[1]=> int(116) }
[2]=> int(124) }
[3]=> int(125) }
...
Bit puzzled so could do with some guidance please. Many thanks.

Replace the following line, where you are creating an individual array for each $term:
$updateTax[] = array($term);
With this:
$updateTax[] = $term;

Optimizing PHP code with two foreach loops

I have an array that consists of the keys:
$countries = ['EU', 'UK', 'Asia'];
Another array that consists of further elements based on those keys:
$countries_array=['UK'=>['London', 'Birmingham', 'Manchester'], 'EU'=> ['Germany','Netherlands'] , 'Asia'=> ['Pakistan','Bangladesh','China']];
$mid_countries[];
I want to pass through all the elements, check if they are empty or not and then further create another array. I have written a code and it works fine. But it has foreach loops. Is there any way that I could optimize this code?
foreach ($countries as $each_country) {
if (!empty($countries_array["$each_country"][0])) {
foreach ($countries_array["$each_country"] as $value) {
$mid_countries[] = array("wildcard" => array("$each_country" => $value. "*"));
}
}
}
Expected result:
array(8) {
[0]=> array(1) { ["wildcard"]=> array(1) { ["EU"]=> string(8) "Germany*" } } [1]=> array(1) { ["wildcard"]=> array(1) { ["EU"]=> string(12) "Netherlands*"}}
[2]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(7) "London*" } } [3]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(11) "Birmingham*" } } [4]=> array(1) { ["wildcard"]=> array(1) { ["UK"]=> string(11) "Manchester*" } } [5]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(9) "Pakistan*" } } [6]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(11) "Bangladesh*"}}
[7]=> array(1) { ["wildcard"]=> array(1) { ["Asia"]=> string(6) "China*" } } }
I think you expected this (Code updated use its working in single loop)
foreach ($countries_array as $key=>$value) {
$tmp=implode('*#'.$key.'#',$value);
$tmp='#'.$key.'#'.$tmp."*";
$tmp=str_replace('#'.$key.'#',"\"}},{\"wildcard\":{\"".$key."\":\"",$tmp);
$result=$result.substr($tmp,3)."\"}}";
}
$result="[".ltrim($result,"\"}},")."]";
$result=json_decode($result,true);
print_r($result);

Assigning specific element of multidimensional array in url in php

My goal is to get specific element/value from a multidimensional array and assign them in a URL in loop. I have already tried and was able to get elements in the array but this displays all elements. I only want to get specific, like nid and field_x values.
This is my link structure: http://localhost:8080/$nid/$field_x
Expected result:
http://localhost:8080/123/one
http://localhost:8080/789/three
This is my sample var_dump result
array(1) {
[0]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(123)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(456)
}
}
["field_x"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(6) "One"
}
}
["field_y"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(2) "Two"
}
}
}
[1]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(789)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(321)
}
}
["field_x"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(6) "Three"
}
}
["field_y"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
string(2) "Four"
}
}
}
}
You can use a foreach() and get the data using $values['nid'][0]['value'] or $values['field_x'][0]['target_id']:
foreach ($result as $values) {
$nid = $values['nid'][0]['value'];
$field_x = $values['field_x'][0]['target_id'];
echo "http://localhost:8080/$nid/$field_x" ;
}
Will outputs:
http://localhost:8080/123/One
http://localhost:8080/789/Three
You probably want to do something else than an echo, so you can create a new array:
$urls = [];
foreach ($result as $values) {
$nid = $values['nid'][0]['value'];
$field_x = $values['field_x'][0]['target_id'];
$urls[] = "http://localhost:8080/$nid/$field_x" ;
}
print_r($urls);

Output and use array elements from a REST Api call in php

I am calling a REST Api to get data using curl in php. It gives me the list of data/contents in the api in Array php format.
I was able to get single element value using $resultArray[0]['nid'][0]['value'];. But my goal is to get elements in all contents in the api.
Say I want to get the following elements in the nested arrays.
$resultArray[0]['nid'][0]['value'];
$resultArray[0]['vid'][0]['value'];
$resultArray[0]['cid'][0]['value'];
And use these values in a loop too.
I am trying to search how I can do it loop, and if anyone can provide sample code, that would be appreciated.
Update:
This is the sample result of var_dump:
array(1) {
[0]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(1)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(2)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(3)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(4)
}
}
}
[1]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(11)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(22)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(33)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(44)
}
}
}
[2]=>
array(38) {
["nid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(111)
}
}
["vid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(222)
}
}
["cid"]=>
array(1) {
[0]=>
array(1) {
["value"]=>
int(333)
}
}
["field"]=>
array(1) {
[0]=>
array(4) {
["target_id"]=>
int(444)
}
}
}
}
And I want to use these elements values in a loop.
Say my expected result is.
Test1 = "1", "2", "3"
Test2 = "11", "22", "33"
Test3 = "111", "222", "333"
These equivalent numbers should be comming from the element nid, vid, cid.
I dont just want to assign/echo these values in the result as I have array[100s] in one api call.
Since your array is a multidimensional array, you need to have nested foreach loops:
$test = 1;
foreach ($resultArray as $items) {
// Echo the current test number
echo "Test{$test} = ";
$values = [];
foreach ($items as $item) {
// Get the correct value.
if (array_key_exists('value', $item[0])) {
$values[] = $item[0]['value'];
continue;
}
if (array_key_exists('target_id', $item[0])) {
$values[] = $item[0]['target_id'];
continue;
}
}
echo '"' . implode('", "', $values) . '"' . "\n";
$test++;
}

PHP how to get value from array with foreach

I have array $result
array(2) {
["Smiley TV"]=>
array(2) {
["Speed"]=>
array(2) {
[0]=>
string(4) "9510"
[1]=>
string(5) "33775"
}
["Turbo"]=>
array(2) {
[0]=>
string(4) "2427"
[1]=>
string(5) "19696"
}
}
["Victory Media"]=>
array(1) {
["Speed"]=>
array(2) {
[0]=>
string(4) "4144"
[1]=>
string(5) "80445"
}
}
}
How with foreach i can get values. For example in the "Smyley TV" how i can result "Speed".
Also please write how i can get all data one by one. Thanks
You can fetch this way
foreach ($arrays as $array) {
echo $array['smyley TV'];
}

Foreach array organization/iteration

I have this array that I've tried iterating over and creating a new array:
array(233) {
[0]=>
array(2) {
["subject_id"]=>
int(138)
["relatedsubject_id"]=>
int(127)
}
[1]=>
array(2) {
["subject_id"]=>
int(138)
["relatedsubject_id"]=>
int(47)
}
[2]=>
array(2) {
["subject_id"]=>
int(138)
["relatedsubject_id"]=>
int(13)
}
[3]=>
array(2) {
["subject_id"]=>
int(138)
["relatedsubject_id"]=>
int(56)
}
[4]=>
array(2) {
["subject_id"]=>
int(154)
["relatedsubject_id"]=>
int(77)
}
[5]=>
array(2) {
["subject_id"]=>
int(154)
["relatedsubject_id"]=>
int(69)
}
[6]=>
array(2) {
["subject_id"]=>
int(154)
["relatedsubject_id"]=>
int(70)
}
[7]=>
array(2) {
["subject_id"]=>
int(154)
["relatedsubject_id"]=>
int(75)
I cut it short so it's not too obnoxious. This is the code I'm using now:
$subject_id = array();
foreach ($results as $mainKey => $subArrays) {
if(!isset($subject_id[$results[$mainKey]["subject_id"]])) {
$subject_id[$results[$mainKey]["subject_id"]] = array();
array_push($subject_id[$results[$mainKey]["subject_id"]], $results[$mainKey]["relatedsubject_id"]);
// $subject_id[$results[$mainKey]["subject_id"]][] = $results[$mainKey]["relatedsubject_id"];
}
}
var_dump($subject_id);
My results look like this:
array(111) {
[138]=>
array(1) {
[0]=>
int(127)
}
[154]=>
array(1) {
[0]=>
int(77)
}
Any ideas on why I'm only getting 1 value and how to modify to get each "relatedsubject_id" to fall in line with the corresponding "subject_id"? Thank you.
Edit
Expected Result:
array {
[138]=>
array(1) {
[0]=>
int(127)
[1]=>
int(47)
[2]=>
int(13)
[3]=>
int(56)
}
[154]=>
array(1) {
[0]=>
int(77)
[1]=>
int(69)
[2]=>
int(70)
[3]=>
int(75)
}
It seems you are trying to consolidate your subject ids and relatedsubject_ids. If thats the case, this may work for you.
$subject_id = array();
foreach ($results as $mainKey => $subArrays) {
if(!isset($subject_id[$results[$mainKey]['subject_id']])) {
$subject_id[$results[$mainKey]['subject_id']] = array('subject_id' => $results[$mainKey]['subject_id'], 'relatedsubject_id' => array());
}
$subject_id[$results[$mainKey]['subject_id']]['relatedsubject_id'][] = $results[$mainKey]["relatedsubject_id"];
}
Changed to your EDIT
$subject_id = array();
foreach ($results as $mainKey => $subArrays) {
if(!isset($subject_id[$results[$mainKey]['subject_id']])) {
$subject_id[$results[$mainKey]['subject_id']] = array();
}
$subject_id[$results[$mainKey]['subject_id']][] = $results[$mainKey]["relatedsubject_id"];
}
The reason why you were only getting one result is you had all your code in the if(!isset()) function. That should only not be set once. If that makes sense.
