I have this array
Array
(
[0] => Array
(
[id] => 1
[job_id] => 100
)
[1] => Array
(
[id] => 2
[job_id] => 100
)
[2] => Array
(
[id] => 3
[job_id] => 101
)
)
Now here how to check if "job_id" is different. eg all have same job_id or not and how many different job_id array have.
Thanks
Try this using array function:
$data = Array
(
[0] => Array
(
[id] => 1
[job_id] => 100
)
[1] => Array
(
[id] => 2
[job_id] => 100
)
[2] => Array
(
[id] => 3
[job_id] => 101
)
)
$totalDifferentJobId = count(array_unique(array_column($data, 'job_id')));
It will give you total unique job
Well, if it is not a too large array, you can do the following:
<?php
$arr = [
['id' => 1, 'job_id' => 100],
['id' => 2, 'job_id' => 100],
['id' => 3, 'job_id' => 101]
];
$jobids = array_unique(array_column($arr, 'job_id'));
var_dump($jobids);
This looks like a db-result, in wich case it would be better to use a group-by statement?

I have a PHP array that I am trying to split into 2 different arrays into that particular array. I am trying to pull out any values for each "destination" and "balance".
Here is the array i get,
Array
(
[destination_1] => 1
[balance_1] => 1
[destination_2] => 2
[balance_2] => 2
[destination_3] => 3
[balance_3] => 3
)
I need output like,
Array (
[0] => Array (
[destination_1] => 1
[balance_1] => 1
)
[1] => Array (
[destination_2] => 2
[balance_1] => 2
)
[2] => Array (
[destination_3] => 3
[balance_3] => 3
)
)
What you need is array_chunk()
$arr = [
"destination_1" => 1,
"balance_1" => 1,
"destination_2" => 2,
"balance_2" => 2,
"destination_3" => 3,
"balance_3" => 3
];
$result = array_chunk($arr, 2, true);
Output:
Array
(
[0] => Array
(
[destination_1] => 1
[balance_1] => 1
)
[1] => Array
(
[destination_2] => 2
[balance_2] => 2
)
[2] => Array
(
[destination_3] => 3
[balance_3] => 3
)
)
How can I make this array:
Array
(
[0] => Array
(
[id] => 3412341233214
[number] => 21000
)
[1] => Array
(
[id] => 12121212121212
[number] => 18000
)
[2] => Array
(
[id] => 12121212121212
[number] => 17000
)
)
Look like the one below, where [1] and [2] have been merged into a single array based on having the same id and the number has been added together.
Array
(
[0] => Array
(
[id] => 3412341233214
[number] => 21000
)
[1] => Array
(
[id] => 12121212121212
[number] => 35000
)
)
Create a $tmp array the store the number property in it.
Only store it if the id doesn't exist yet using:
if(!isset($tmp[$obj['id']]))
To make each value unique
After that, count the $tmp number with the $array number.
$tmp[$obj['id']]['number'] += $obj['number'];
https://3v4l.org/UMJ4p
$array = array(
0 => array(
"id" => 3412341233214,
"number" => 21000
),
1 => array(
"id" => 12121212121212,
"number" => 18000
),
2 => array(
"id" => 12121212121212,
"number" => 17000
)
);
$tmp = Array();
foreach($array as $obj) {
if(!isset($tmp[$obj['id']])) {
$tmp[$obj['id']] = array_merge(Array('number'=>1),$obj);
continue;
}
$tmp[$obj['id']]['number'] += $obj['number'];
}
print_r(array_values($tmp));
The following code results into
(
[0] => Array
(
[number] => 21000
[id] => 3412341233214
)
[1] => Array
(
[number] => 35000
[id] => 12121212121212
)
)
I am working in PHP so I have an array like this, from this array I want filter take user_id to another array like I given below.
Array
(
[0] => Array
(
[user_id] => 66
[distance] => 0
)
[1] => Array
(
[user_id] => 68
[distance] => 0
)
[2] => Array
(
[user_id] => 81
[distance] => 0
)
[3] => Array
(
[user_id] => 65
[distance] => 0.00010218008081861118
)
)
I want an array like this,
$user_id=array(66,68,81,65);
Use array_column()
Returns an array of values representing a single column from the input array.
<?php
$user_array = array(
0 => array('user_id' => 1, 'name' => 'Bob'),
1 => array('user_id' => 2, 'name' => 'John'),
2 => array('user_id' => 3, 'name' => 'Mary')
);
$users = array_column($user_array, 'user_id');
print_r($users);
Output :
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Where $array is the multidimensional array you provided above:
$data = array();
foreach ($array as $item) {
$data[] = $item['user_id'];
}
print_r($data);

How to manipulate php arrays. I have a $data variable below.
$data = Array
(
[0] => Array
(
[id] => 1
[capacity] => 900
[category] => users
)
[1] => Array
(
[id] => 2
[capacity] => 300
[category] => users
)
[2] => Array
(
[id] => 3
[capacity] => 900
[category] => students
)
[3] => Array
(
[id] => 4
[capacity] => 300
[category] => students
)
)
Now I want to group the data with same category like below. . I am not really familiar in php. Can somebody out there help me how to achieve this. What function should I used. Thanks
Array
(
[users] => Array
(
[0] => Array
(
[id] => 1
[capacity] => 900
[category] => users
)
[1] => Array
(
[id] => 2
[capacity] => 300
[category] => users
)
),
[students] => Array
(
[0] => Array
(
[id] => 1
[capacity] => 900
[category] => students
)
[1] => Array
(
[id] => 2
[capacity] => 300
[category] => students
)
)
)
Just iterate over the array and add it depending on the content of the category field to a new array:
$new = array();
foreach ($data as $val) {
$new[$val['category']][] = $val;
}
This does what you requested
<?php
$data = array(
0 => array (
"id" => 1,
"capacity" => 900,
"category" => "users"
),
1 => array (
"id" => 2,
"capacity" => 300,
"category" => "users"
),
2 => array (
"id" => 3,
"capacity" => 900,
"category" => "students"
),
3 => array (
"id" => 4,
"capacity" => 300,
"category" => "students"
)
);
$groups = array();
foreach ($data as $i) {
if ($i['category'] === "students") {
$groups['students'][] = $i;
}
else if ($i['category'] === "users") {
$groups['users'][] = $i;
}
}
echo "<pre>", print_r($groups), "</pre>";
