I'm using a form where the pair of inputs can be added per automatic. One store value in select and the other as input
After submit I receive the values in array and I need to associate them together. So all key values [0] belongs together and all [1] and so on.
Array
(
[issue] => Array
(
[0] => 2
[1] => 3
)
[qty] => Array
(
[0] => 1
[1] => 2
)
)
How can I do this using PHP?
Just use a simple foreach loop.
$combined = array();
foreach ($_POST["issue"] as $k=>$v) {
$combined[$k] = array($_POST["issue"][$k], $_POST["qty"][$k]);
}
print_r($combined);

I am working with php and arrays, I have multiple arrays like following
Array
(
[0] => Array
(
[wallet_address] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
)
[1] => Array
(
[wallet_address] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
[2] => Array
(
[wallet_address] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
and so on....
And i want to make them in single array with comma like following way
$set = array("0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx","0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx","0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
How can i do this ?Here is my current code but not working,showing me same result(0,1,2 keys),Where i am wrong ?
$GetUserFollower; //contaning multiple array value
$set=array();
foreach($GetUserFollower as $arr)
{
$set[]=$arr;
}
echo "<pre>";print_R($set);
The original array is an Assoc array and therefore the wallet_address needs to be addressed specifically in a loop. Or you could use the array_column() builtin function to achieve the same thing.
$GetUserFollower; //contaning multiple array value
$set=array();
foreach($GetUserFollower as $arr)
{
$set[] = $arr['wallet_address'];
}
echo "<pre>";print_r($set);
Or
$new = array_column($GetUserFollower, 'wallet_address');
print_r($new);
RESULT
Array
(
[0] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
[1] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
[2] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)
Your comments are making me think you want an array without a key, which is impossible. If you do this with the example you show in your comments
$set = array("0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx","0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx","0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
print_r($set);
You will see
Array
(
[0] => 0x127e61982701axxxxxxxxxxxxxxxxxxxxxxxxxxx
[1] => 0xf80a41eE97e3xxxxxxxxxxxxxxxxxxxxxxxxxxxx
[2] => 0x24361F1602bxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
)

i have tried with 2 foreach but i didnt manage to get it done. I have read Create a multidimensional array in a loop , how to create multidimensional array using a foreach loop in php? , create multidimensional array using a foreach loop , Converting an array from one to multi-dimensional based on parent ID values and some more but i still cant do it. Any tips on how to create it?
You just need to loop over the input array and build the new array
$new = [];
foreach ($in as $key=>$arr) {
$new[0][$key] = $arr[0];
$new[1][$key] = $arr[1];
}
<?php
$result = [];
for ($i=0; $i<count(reset($array)); $i++) {
$result[] = array_combine(array_keys($array), array_column($array, $i));
}
Please read the manual for more details about array_combine(), array_keys() and array_column().
So I want to delete an array element from a JSON array based on an id in a sub-array. I know it sounds weird. Here's an example of the array. I want to delete the entire array [0] based on the [dealer][id] array where the [id] = 20220 in this example.
Array
(
[results] => Array
(
[offset] => 1
[length] => 15
[data] => Array
(
[0] => Array
(
[dealer] => Array
(
[id] => 20220
[name] => apple
)
)
)
)
}
In reality there are a lot more elements in the [results] array. I'm not sure how to go about it.
Any help is greatly appreciated!
Loop thru data key first then check if dealer id matches the searched id
$id = 20220;
foreach ($array['results']['data'] as $key => $value) {
if ($value['dealer']['id'] == $id) {
unset($array['results']['data'][$key]);
}
}
use array_filter,
$array['results']['data'] = array_filter($array['results']['data'], function($v){return $v['dealer']['id'] != 20220;});
I am creating a set of arrays with the following loop:
$assessmentArr = explode("&", $assessmentData);
foreach($assessmentArr as $data) {
$fullArr = explode("_", $data);
// Break down to only archetype and value
$resultArr = explode("=", $fullArr[2]);
//print_r($resultArr);
}
Which produces the following results:
Array
(
[0] => community-support
[1] => 24
)
Array
(
[0] => money-rewards
[1] => 30
)
Array
(
[0] => status-stability
[1] => 15
)
Array
(
[0] => personal-professional-development
[1] => 32
)
Array
(
[0] => community-support
[1] => 9
)
Array
(
[0] => money-rewards
[1] => 12
)
Array
(
[0] => status-stability
[1] => 16
)
Array
(
[0] => personal-professional-development
[1] => 29
)
I need to combine these into one array, and where the [0] value matches, I need to add the [1] value together.
So I would like the final output to be something like:
Array
(
[community-support] => 33
[money-rewards] => 42
[status-stability] => 31
[personal-professional-development] => 61
)
I found this question: How to merge two arrays by summing the merged values which will assist me in merging and adding the values together, but I'm not sure how to go about it when the arrays aren't assigned to a variable. Is what I am trying to do possible or am I going about this the wrong way?
Don't make it complicated, just check if the results array already has an element with that key and if not initialize it otherwise add it. E.g.
(Add this code in your loop):
if(!isset($result[$resultArr[0]]))
$result[$resultArr[0]] = $resultArr[1];
else
$result[$resultArr[0]] += $resultArr[1];
Then you have your desired array:
print_r($result);
You could do it like this
$assessmentArr = explode("&", $assessmentData);
$finalArr = array();
foreach($assessmentArr as $data) {
$fullArr = explode("_", $data);
// Break down to only archetype and value
$resultArr = explode("=", $fullArr[2]);
if(array_key_exists($resultArr[1], $finalArr)){
$finalArr[$resultArr[0]] += $resultArr[1];
}else{
$finalArr[$resultArr[0]] = $resultArr[1];
}
}
First check, if the key already exists in the array, if so you add the value to the value in the final array. Otherwise you add the new index to the final array, with the value from resultArr as inital value.
... way too slow :/
Below is a array generated by a query builder.
$random_array = Array ( [0] => Array ( [text] => A great time was had by all! )
[1] => Array ( [text] => KILL SHOT )
[2] => Array ( [text] => How is it possible)
[3] => Array ( [text] => http://www.youtube.com/watch?v=KwGOZpbxU9g )
[4] => Array ( [text] => http://www.youtube.com/watch?v=KwGOZpbxU9g )
)
Currently i am doing like this to print the random value
print_r(array_rand($random_array,1));
This is printing the array key as 3 or 1 etc(random from above array).I want to print the value of the key and not the key.
e.g I want to print the random value like this "http://www.youtube.com/watch?v=KwGOZpbxU9g" or "A great time was had by all!" instead of 3 or 1 which is printing now.
Is it possible to do this.
You will have one more line of code as shown below:
$array_key = array_rand($random_array,1); //get the key
print_r( $random_array[$array_key] ); //use the key to print value
What about simply calling
$randNumber = rand(0,count($random_array))-1; //index in array starts with 0
print (string) $random_array[$randNumber];
