How to attach array in php - php

I have an array structure like this
Array
(
[0] => Array
(
[C:/xampp/htdocs/rosoka/file] => Array()
)
[1] => Array
(
[C:/xampp/htdocs/rosoka/file/2018-03-02] => Array()
)
[2] => Array
(
[C:/xampp/htdocs/rosoka/file/2018-03-03] => Array()
)
)
how to add some an array on key specific like
[C:/xampp/htdocs/rosoka/file] => Array('duck','buffalo')

1.You can do it like below:-
$array[0]['C:/xampp/htdocs/rosoka/file'] = ['duck','buffalo'];
Output:-https://eval.in/984253
2.Or if some values are already present there:-
$array[0]['C:/xampp/htdocs/rosoka/file'][] = 'buffalo';
Output:-https://eval.in/984254
3.Or if you want to search key first and then try to add:-
foreach($array as $key=>$value){
if(array_keys($value)[0] == 'C:/xampp/htdocs/rosoka/file'){
$array[$key]['C:/xampp/htdocs/rosoka/file'][] = 'buffalo';
}
}
Output:-https://eval.in/984255

For your requirement, you can assign an Array value to key specific like below:
$array[0]['C:/xampp/htdocs/rosoka/file'] = Array('duck','buffalo');
$array[1]['C:/xampp/htdocs/rosoka/file/2018-03-02'] = Array('duck','buffalo');
If you use $array[0]['C:/xampp/htdocs/rosoka/file'][] at left side like this it will again become an Array, hence accessing values will be changed. There is no need of having [] again.

How to append to an array key's value php

Let's say I have an array like this:
[["code1": '528'], ["code2": '292'], ["code1": '108']]
I am looping through the array to check if a specific key exists. If it doesn't then I am adding it to another array:
$arr[$codename] = $code
However, if the key already exists, then I want to append the $code value to the existing key's values. I'm not sure how to do this part.
I want the new array to look like this:
[["code1": '528', '108'], ["code2", '292']]
You can try:
$array = [['code1' => 528], ['code2' => 292], ['code1' => 108]];
$newArray = [];
foreach ($array as $value) {
$newArray[array_key_first($value)][] = $value[array_key_first($value)];
}
print_r($newArray);
Result:
Array
(
[code1] => Array
(
[0] => 528
[1] => 108
)
[code2] => Array
(
[0] => 292
)
)

PHP recursive function returning null array

I have a huge array in which keys are also not constant in most of the cases, but there are 3 keys that always constant (#name,#default_value,#value) and #default_value and #value is different i want to get these kind of sub arrays in 1 simple array , for this purpose i am using recursion in whole array and checking out if these 3 keys are present there i can print these values inside recursion easily but I am not able to get those values in return. So that i can precess them further.
$form=array();
$form['field_one']['#name']="field_one";
$form['field_one']['#default_value']="old";
$form['field_one']['#value']="new";
$form['field_two']['#name']="field_two";
$form['field_two']['#default_value']="old";
$form['field_two']['#value']="new";
$form['field_three']['#name']="field_three";
$form['field_three']['#default_value']="old";
$form['field_three']['#value']="old";
$form['thiscouldbeanotherarray']['idk']['field_four']['#name']="field_four";
$form['thiscouldbeanotherarray']['idk']['field_four']['#default_value']="old";
$form['thiscouldbeanotherarray']['idk']['field_four']['#value']="new";
$arr_get = get_updatedvalues($form,array());
var_dump($arr_get);
function get_updatedvalues($form,$fields) {
if (!is_array($form)) {
return;
}
foreach($form as $k => $value) {
if(str_replace('#','',$k) =='default_value' && ($form['#default_value'] != $form['#value'] ) ){
$fields['field'][$form['#name']] = array("name" => $form['#name'],"old_value" =>$form['#default_value'],"new_value" =>$form['#value']);
var_dump($fields);
}
get_updatedvalues($value,$fields);
}
return $fields;
}
If you run this code it will give you $arr_get > array (size=0), there i need all three values
If I understand correctly, you need to pass fields as a reference in order to change it:
function get_updatedvalues($form, &$fields) {
To do that, however, you'll need to change your initial call so that you have a variable to pass as the reference:
$array = [];
$arr_get = get_updatedvalues($form,$array);
Running this I get:
Array
(
[field] => Array
(
[field_one] => Array
(
[name] => field_one
[old_value] => old
[new_value] => new
)
[field_two] => Array
(
[name] => field_two
[old_value] => old
[new_value] => new
)
[field_four] => Array
(
[name] => field_four
[old_value] => old
[new_value] => new
)
)
)

How to count items in an array that's in an array?

How do you count items in an array that's part of an array? I'm using Advance Custom Fields plugin in WordPress and my array print_r(get_field('irl_today_entry')) output looks like this:
Array
(
[0] => Array
(
[acf_fc_layout] => irl_today_website_entry
[irl_today_website] => Array
(
[0] => Array
( data removed)
[1] => Array
( data removed )
)
)
[1] => Array
(
[acf_fc_layout] => irl_today_social_entry
[irl_today_social] => Array
(
[0] => Array
( data remove )
[1] => Array
( data remove)
)
)
)
How do you only count items in [irl_today_social]? I've tried a lot of options that do not work.
If you have multiple entries with irl_today_social you might also use array_map and array_column
$res = array_map(function($x) {
return count($x);
}, array_column($arrays, "irl_today_social"));
print_r($res);
Output
Array
(
[0] => 2
)
See a php demo
You can use array_reduce,
array_reduce(get_field('irl_today_entry'),function($a,$b){
return count($a["irl_today_website"]) + count($b["irl_today_website"]);
});
Loop through your array, get the count of your desired index, and add that to a counter.
$count = 0;
foreach(get_field('irl_today_entry') as $entry){
$count = $count + count(entry['irl_today_social']);
}
Simply you can use "Count" Function
Here is the Solution:
Step 1: First get your array items of ['irl_today_entry'].
Step 2 Then Count your ['irl_today_social'] items.
Example:
foreach(get_field('irl_today_entry') as $entry){
$socialData = count(entry['irl_today_social']);
}
Thanks
according to my understaing just simply try this
echo count($your_array[1]['irl_today_social']);

Through an array with other array in php

I have a question for you, I need to through an array with other arrays in php but i through only the last array, my array is:
Array
(
[0] => Array
(
[syn_id] => 17070
[syn_label] => fd+dfd
)
[1] => Array
(
[syn_id] => 17068
[syn_label] => fds+dsfds
)
[2] => Array
(
[syn_id] => 17069
[syn_label] => klk+stw
)
)
My php:
$a_ddata = json_decode(method(), true);
foreach ($a_ddata as $a_data)
{
$a_data['syn_label'] = urldecode(utf8_decode($a_data['syn_label']));
}
With this code I through only the last array [2], but how to through array?please help me
I need to get the array:
Array
(
[0] => Array
(
[syn_id] => 17070
[syn_label] => fd dfd
)
[1] => Array
(
[syn_id] => 17068
[syn_label] => fds dsfds
)
[2] => Array
(
[syn_id] => 17069
[syn_label] => klk stw
)
)
$a_ddata = json_decode(method(), true); $i=0;
foreach ($a_ddata as $a_data)
{
$a_data_f[$i]['syn_id'] = $a_data['syn_id'];
$a_data_f[$i]['syn_label'] = urldecode(utf8_decode($a_data['syn_label']));
$i++;
}
This should be your answer..
When you iterate through something using foreach, by default PHP makes a copy of each element for you to use within the loop. So in your code,
$a_ddata = json_decode(method(), true);
foreach ($a_ddata as $a_data)
{
// $a_data is a separate copy of one of the child arrays in $a_ddata
// this next line will modify the copy
$a_data['syn_label'] = urldecode(utf8_decode($a_data['syn_label']));
// but at the end of the loop the copy is discarded and replaced with a new one
}
Fortunately the manual page for foreach gives us a way to override this behavior with the reference operator &. If you place it between the as keyword and your loop variable, you're able to update the source array within your loop.
$a_ddata = json_decode(method(), true);
foreach ($a_ddata as &$a_data)
{
// $a_data is now a reference to one of the elements to $a_ddata
// so, this next line will update $a_ddata's individual records
$a_data['syn_label'] = urldecode(utf8_decode($a_data['syn_label']));
}
// and you should now have the result you want in $a_ddata
This should help:
$a_data['syn_label'][] = urldecode(utf8_decode($a_data['syn_label']));
For each iteration you are only replacing $a_data['syn_label']. By adding [] you are making it a multi dimension array which increments for every iteration.

php remove duplicates based on first value of multidimensional array

Given
[0] => Array
(
[0] => ask.com
[1] => 2320476
)
[1] => Array
(
[0] => amazon.com
[1] => 1834593
)
[2] => Array
(
[0] => ask.com
[1] => 1127456
)
I need to remove duplicate values solely based on first value, regardless of what any other subsequent values may be. Notice [0][1] differs from [2][1] yet I consider this as a duplicate because there are two matching first values. The other data is irrelevant and shouldn't be considered in comparison.
Try this, assuming that $mainArray is the array you have.
$outputArray = array(); // The results will be loaded into this array.
$keysArray = array(); // The list of keys will be added here.
foreach ($mainArray as $innerArray) { // Iterate through your array.
if (!in_array($innerArray[0], $keysArray)) { // Check to see if this is a key that's already been used before.
$keysArray[] = $innerArray[0]; // If the key hasn't been used before, add it into the list of keys.
$outputArray[] = $innerArray; // Add the inner array into the output.
}
}
print_r($outputArray);
