I have 2 db queries that return values from the db, what's the easiest way to do this. Is there a PHP function that can do this or do I have to use a loop ?
$names = array(
'det-1' => array('foo'),
'det-2' => array('bar'),
'det-3' => array('doe')
);
$emails = array(
'det-1' => array('foo#gmail.com'),
'det-2' => array('bar#gmail.com'),
'det-3' => array('doe#gmail.com')
);
// the result
$details = array(
'det-1' => array('foo', 'foo#gmail.com')
'det-2' => array('bar', 'bar#gmail.com')
'det-3' => array('doe', 'doe#gmail.com')
);
Use array_merge_recursive():
php > print_r(array_merge_recursive($names, $emails));
Array
(
[det-1] => Array
(
[0] => foo
[1] => foo#gmail.com
)
[det-2] => Array
(
[0] => bar
[1] => bar#gmail.com
)
[det-3] => Array
(
[0] => doe
[1] => doe#gmail.com
)
)
You can use array_merge_recursive
$newArray = array_merge_recursive($names, $emails);

This question already has answers here:
Group subarrays by one column, make comma-separated values from other column within groups
(2 answers)
Closed last month.
here's how it looks in the PHP code:
<?php
$array = array(
array(
'name' => 'filter_amount',
'value' => '100-ml'
),
array(
'name' => 'filter_amount',
'value' => '200-ml'
),
array(
'name' => 'page_size',
'value' => '7'
)
);
print_r($array);
?>
Example of print_r() function output:
Array
(
[0] => Array
(
[name] => filter_amount
[value] => 100-ml
)
[1] => Array
(
[name] => filter_amount
[value] => 200-ml
)
[2] => Array
(
[name] => page_size
[value] => 7
)
)
I need to combine duplicates of filter_amount values from the array.
The values of these duplicates must be commas separated and the result should be the following code:
Array
(
[0] => Array
(
[name] => filter_amount
[value] => 100-ml,200-ml
)
[1] => Array
(
[name] => page_size
[value] => 7
)
[2] => Array
(
[name] => orderby
[value] => rating
)
[3] => Array
(
[name] => paged
[value] => 1
)
)
Since you want value to be concatenated by a comma, you'll have to make a cycle of it
<?php
//Allow me to change this variable name, just to not create confusion
$content = array(
array(
'name' => 'filter_amount',
'value' => '100-ml'
),
array(
'name' => 'filter_amount',
'value' => '200-ml'
),
array(
'name' => 'page_size',
'value' => '7'
)
);
//$content is your initial array
//$outputArray is the final worked-up array
$outputArray = [];
//Let's make a cycle going for every array inside $content
foreach ($content as $innerArray) {
//Does this $innerArray['name'] (filter_ammount) exist in $outputArray in an array
//consisting in key => value where the key is 'name' and equals
//what we look for that is(filter_ammount)?
$key = array_search($innerArray['name'], array_column($outputArray , 'name'));
//If not, let's place this array in the $output array
if ($key === false) {
array_push($outputArray, $innerArray);
} else {
//If exists, then $key is the $key of the $outputArray and let's add to its value
//our current value, that is in our $innerArray, concatenated with a comma
$outputArray[$key]['value'] .= ",". $innerArray['value'];
}
}
//Boom, magic
print_r($outputArray);
//Note: This is going to affect every duplicate it finds, as in:
//If you got 3 arrays with name 'filter_ammount' and 2 arrays with name
//'page_size', it's going to concatenate the filter_ammount and the 'page_size'.
//If you specifically just want filter_ammount,
//replace this -> $key = array_search($innerArray['name'], array_column($outputArray , 'name'));
//with this -> $key = array_search('filter_ammount', array_column($outputArray , 'name'));
?>

Try this:
<?php
$array = array(
array(
'name' => 'filter_amount',
'value' => '100-ml'
),
array(
'name' => 'filter_amount',
'value' => '200-ml'

$tmp = array();
foreach($array as $val) {
$tmp[$val['name']]['values'][] = $val['value'];
}
foreach($tmp as $k => $v) {
$item = implode(',', array_unique(explode(',', implode(',',$v['values']))));
$newArr[] = array('name' => $k, 'value' => $item);
}
echo '<pre>';
print_r($newArr);
echo '</pre>';
got it with the following crazy mess:
$name = array_column($array, 'name');
$value = array_column($array, 'value');
foreach($name as $nk=>$nv)
foreach($value as $vk=>$vv)
if($nk == $vk)
$a[$nv][] = $vv;
foreach($a as $k=>$v)
$b[$k] = implode(',', $v);
$z = 0;
foreach($b as $k=>$v)
{
$c[$z]['name'] = $k;
$c[$z]['value'] = $v;
$z++;
}
$c is the resulting array
Or using a medley of array functions:
<?php
$array = array(
array(
'name' => 'filter_amount',
'value' => '100-ml'
),
array(
'name' => 'filter_amount',
'value' => '200-ml'
),
array(
'name' => 'page_size',
'value' => '7'
)
);
$names = array_column($array, 'name');
$values = array_column($array, 'value');
$result = [];
foreach (array_unique($names) as $k)
$result[$k] = implode(", ", array_filter($values,
function($v, $indx) use ($names, $k) {
return $names[$indx] == $k;
}, ARRAY_FILTER_USE_BOTH));
print_r($result);
$result2 = [];
foreach ($result as $k=>$v) $result2[] = ['name'=>$k, 'value'=>$v];
print_r($result2);
Results in:
Array
(
[filter_amount] => 100-ml, 200-ml
[page_size] => 7
)
Array
(
[0] => Array
(
[name] => filter_amount
[value] => 100-ml, 200-ml
)
[1] => Array
(
[name] => page_size
[value] => 7
)
)
All of the other answers up to now are using two or more iterating techniques for this task. There only needs to be one loop.
Build an associative output array based on the name values as you iterate. If the associative key isn't set, then save the whole row. If it is set, then just append a comma then the new value data to the stored value element.
Using temporary keys allows isset() to swiftly check for existence. It will always outperform array_search() and in_array() because of how php treats arrays (as hash maps).
Remove the temporary keys when the loop is finished by calling array_values().
Code: (Demo)
$result = [];
foreach ($array as $row) {
if (!isset($result[$row['name']])) {
$result[$row['name']] = $row;
} else {
$result[$row['name']]['value'] .= ',' . $row['value'];
}
}
var_export(array_values($result));
Output:
array (
0 =>
array (
'name' => 'filter_amount',
'value' => '100-ml,200-ml',
),
1 =>
array (
'name' => 'page_size',
'value' => '7',
),
)
I'm currently looking for a solution to this problem:
if I have something like that:
Array
(
[0] => Array
(
[id] => 1
[name] => Timer
)
[1] => Array
(
[id] => 2
[name] => Tub
)
[3] => Array
(
[id] => 1
[name] => Paper
)
[4] => Array
(
[id] => 4
[name] => Puppy
)
)
The goal I'd like to reach here is create a new array which contains the arrays with the same ID. So basically, at the end I'm gonna have two arrays: the first will contain element with different IDs and the second will contain element with the same ID.
Any tips? Thank you in advance!
One way is by mainly using array_filter()
// Gather ids and count
$id = array_count_values(array_column($array, 'id'));
// Filter not unique
$notUnique = array_filter($array, function($e) use ($id) {
return ($id[$e['id']] > 1);
});
// Filter unique
$unique = array_filter($array, function($e) use ($id) {
return !($id[$e['id']] > 1); // or ($id[$e['id']] == 1)
});
// Print result
print_r($notUnique);
echo '<br>';
print_r($unique);
Try this
<?php
$array = array(
array('id' => 1,'name' => 'Timer'),
array('id' => 2,'name' => 'Tub'),
array('id' => 1,'name' => 'Paper'),
array('id' => 4,'name' => 'Puppy')
);
$new = array();
foreach($array as $r)$new[$r['id']][] = $r['name'];
echo '<pre>';print_r($new);
?>
Output
Array
(
[1] => Array
(
[0] => Timer
[1] => Paper
)
[2] => Array
(
[0] => Tub
)
[4] => Array
(
[0] => Puppy
)
)
This is probably not so hard, but I have searched for a while with no luck so any help will be appreciated.
I'm working in PHP with two arrays which contain a number of multidimensional arrays each with a set of two values. The 2 arrays looks something like this:
Array
(
[0] => Array
(
[0] => 3206.63
[1] => 815.47
)
[1] => Array
(
[0] => 5024.71
[1] => 803.73
)
[2] => Array
(
[0] => 3290.36
[1] => 625.02
)
//...
)
Array
(
[0] => Array
(
[0] => 3138.87
[1] => 819.8
)
[1] => Array
(
[0] => 5000.24
[1] => 810.87
)
[2] => Array
(
[0] => 3221.15
[1] => 668.58
)
//...
)
And I need to achieve this:
Array
(
[0] => Array
(
[0] => 6345.5
[1] => 1635.27
)
[1] => Array
(
[0] => 10024.95
[1] => 1614.6
)
[2] => Array
(
[0] => 6511.51
[1] => 1293.6
)
//...
)
This should work for you:
(Here i loop though each innerArray with foreach and use array_sum() to get the sum of all values of each innerArray)
<?php
$arr = array(
array(
3206.63,
815.47
),
array(
5024.71,
803.73
),
array(
3290.36,
625.02
)
);
$result = array();
foreach($arr as $v)
$result[] = array_sum($v);
print_r($result);
?>
Output:
Array ( [0] => 4022.1 [1] => 5828.44 [2] => 3915.38 )
If you have 2 Arrays you can use this:
$result = array();
foreach($arr1 as $k => $v)
$result[] = array_sum($arr1[$k]) + array_sum($arr2[$k]);
print_r($result);
EDIT:
From your updated question, this should work for you:
<?php
$arr1 = array(
array(
3206.63,
815.47
),
array(
5024.71,
803.73
),
array(
3290.36,
625.02
)
);
$arr2 = array(
array(
3138.87,
819.8
),
array(
5000.24,
810.87
),
array(
3221.15,
668.58
)
);
$sums = array();
foreach ($arr1 as $key => $value) {
$sums[$key][] = $arr1[$key][0] + $arr2[$key][0];
$sums[$key][] = $arr1[$key][1] + $arr2[$key][1];
}
print_r($sums);
?>
Output:
Array
(
[0] => Array
(
[0] => 6345.5
[1] => 1635.27
)
[1] => Array
(
[0] => 10024.95

I am using PHP. Can anyone point me to a good starting point as to how I should go about doing this?
You can use array_merge():
$new_array[0] = array_merge($array[0], $array[1]);
Where $array is the first array.
SEE DEMO
OR for a more dynamic approach:
$new_array = array(0 => array());
foreach($array as $a) {
$new_array[0] = array_merge($new_array[0], $a);
}
SEE DEMO 2
The simpliest solution is to do it with:
$input = array(
array(
array('ConsumerID' => 1, 'name' => 'asdfd'),
array('ConsumerID' => 5, 'name' => 'test'),
array('ConsumerID' => 4, 'name' => 'test1'),
),
array(
array('ConsumerID' => 4, 'name' => 'test4'),
),
);
$output = array(
array()
);
foreach ($input as $data) {
$output[0] = array_merge($output[0], $data);
}
Try this->
$newArray = array();
foreach($values as $key=>$val){
$newArray [0][$key]=$val;
}
print_r($newArray);
Check this:
<?php
$arr[0] = array(0 => array("ConsumerID" => 1, "name" => "Ni"), 1 => array("ConsumerID" => 2, "name" => "Ab"));
$arr[1] = array(1 => array("ConsumerID" =>5, "name" => "GE"), 1 => array("ConsumerID" => 6, "name" => "DB"));
$new = array();
foreach($arr as $key => $value) {
foreach($value as $innerkey => $innervalue) {
$new[0][] = $innervalue;
}
}
print_r($new);
?>
I have an array like this.

[1] => Array
(

I have tried unset function but it still doesn't work as i expected.
I am not big into array concept and hence my stupid questions !!! :(
I think that it'd be better to use array_map instead of unset:
function filter($x)
{
return $x['email'];
}
$emails = array_map('filter', $your_array);
This basically will map your input array into output array using filter function.
foreach($foo as $key=>$value)
{
$foo[$key] = $value['email'];
}
Simply pick from your old array what you want and put it in a new one.
$newArray = array();
foreach($oldArray as $containedArray)
{
$newArray[] = $containedArray['email'];
}
var_dump($newArray);
<?php
$array = Array
(
Array
(
email => 'abc#gmail.com',
timestamp => '2013-05-03 09:20:01'
),
Array
(
email => 'def#yahoo.co.in',
timestamp => '2013-05-03 09:20:23'
),
Array
(
email => 'ghi#gmail.com',
timestamp => '2013-05-03 09:20:43'
),
);
foreach ($array as $array){
$newArray[] = $array['email'];
}
var_dump($newArray);
There is no need to unset anything. Just assign the appropriate value:
<?php
$array = array(
array(
"email" => 'aaa#aaa.com',
"timestamp" => 2,
),
array(
"email" => 'bbb#aaa.com',
"timestamp" => 3,
),
);
foreach($array as $key => $value)
{
$array[$key] = $value["email"];
}
var_dump($array);
Try this,
<?php
$array= array(
0 => array
(
'email' => 'abc#gmail.com',
'timestamp' =>' 2013-05-03 09:20:01'
),
1 => array
(
'email'=> 'def#gmail.com',
'timestamp' => '2013-05-03 09:20:23'
),
2 => array
(
'email'=> 'ghi#gmail.com',
'timestamp' => '2013-05-03 09:20:43'
)
);
foreach($array as $key => $data)
{
$array[$key]=$data['email'];
}
print_r($array);
?>
You will get
Array
(
[0] => abc#gmai1.com
[1] => def#gmail.com
[2] => ghi#gmail.com
)
