$arr = Array
(
[0] => Array
(
[PropertyID] => 11
)
[1] => Array
(
[PropertyID] => 22
)
[2] => Array
(
[PropertyID] => 33
)
[3] => Array
(
[PropertyID] => 44
)
)
$excludeIDs = Array(22, 11, 44);
Desired outcome:
Array ( [0] => Array ( [PropertyID] => 33 ) )
I want to exclude the arrays that contain a matching PropertyID inside $excludeIDS
How may I do this?
Use unset() through the array:
foreach($arr as $key => $value){
if(in_array($value['PropertyID'], $excludeIDs)){
unset($arr[$key]);
}
}
$arr = array_values($arr);
print_r($arr);
Output:
Array
(
[0] => Array
(
[PropertyID] => 33
)
)
Try this :
<?php
$excludeIDs = array(22, 11, 44);
$counter = 0;
foreach ($arr as $key => $value) {
if (!in_array($value['PropertyID'], $excludeIDs)) {
$result_array[$counter] = $value;
$counter++;
}
}
echo '<pre>';
print_r($result_array);
echo '</pre>';
?>

I'd like to change the values of an array.
Currently my array looks like this:
Array
(
[0] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
)
)
I want to remove everything before the + symbol, so in the end the new array will looke like this
Array
(
[0] => Array
(
[0] => Yes
[1] => N/A
[2] => No
)
)
This is my code:
$new_array = array();
foreach( $array as $key => $value ) {
$split = explode("+", $value[0]);
$new_array[] = $split[1];
}
Hoping that it would worked, but when I check the new array, it only shows one value.
Array
(
[0] => Yes
)
Any help in putting me in the right direction is much appreciated.
Please, check it:
<?php
$array[0][0] = '12-Multi_select-customfield-retina-ready+Yes';
$array[0][1] = '12-Multi_select-customfield-retina-ready+N/A';
$array[0][2] = '112-Multi_select-customfield-retina-ready+No';
echo '<pre>';
print_r($array);
$new_array = array();
foreach( $array[0] as $key => $value ) {
$split = explode("+", $value);
$new_array[] = $split[1];
}
print_r($new_array);
echo '</pre>';
Try This this work even if you have multiple key in the original array $original_array[0], $original_array[1] ... :
$original_array[0] = [
0 => '12-Multi_select-customfield-retina-ready+Yes',
1 => '12-Multi_select-customfield-retina-ready+N/A',
2 => '12-Multi_select-customfield-retina-ready+No'
];
print_r($original_array);
$new_array = [];
foreach ($original_array as $key => $value) {
foreach ($value as $index => $val) {
$split = explode("+", $val);
$new_array[$key][] = $split[1];
}
}
print_r($new_array);
Example :
Original array
Array
(
[0] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
),
[1] => Array
(
[0] => 12-Multi_select-customfield-retina-ready+Yes
[1] => 12-Multi_select-customfield-retina-ready+N/A
[2] => 12-Multi_select-customfield-retina-ready+No
)
)
New Array
Array
(
[0] => Array

I have a multi-dimensional array. Since the value of the string "volvo" is present twice, I want to combine those keys. Here's the source array:
Array
(
[0] => Array
(
[0] => Volvo
[1] => 22
)
[1] => Array
(
[0] => BMW
[1] => 15
)
[2] => Array
(
[0] => Saab
[1] => 5
)
[3] => Array
(
[0] => Volvo
[1] => 17
)
)
and I'd like to convert it to this one:
Array
(
[0] => Array
(
[0] => Volvo
[1] => 39
)
[1] => Array
(
[0] => BMW
[1] => 15
)
[2] => Array
(
[0] => Saab
[1] => 5
)
)
I think this would make more sense to return an associated array, that way you can do $arr["volvo"], if you're fine with an associated array, just remove the second foreach loop.
If not, this will get the correct output:
<?php
$arr = Array (
Array (
"Volvo",
22
),
Array (
"BMW",
15
),
Array (
"Saab",
5
),
Array (
"Volvo",
17
)
);
$tmpNewArr = Array();
foreach ($arr as $ele) {
if (!isset($arr[$ele[0]])) {
$tmpNewArr[$ele[0]] = 0;
}
$tmpNewArr[$ele[0]] += $ele[1];
}
$newArr = [];
foreach ($tmpNewArr as $key => $ele) {
array_push($newArr,[$key,$ele]);
}
var_dump($newArr);
?>
Here's an eval.in:
https://eval.in/766340
$keyValueCars = [];
foreach($cars as $car){
$brand = $car[0];
$total = $car[1];
if(!isset($keyValueCars[$brand])){
$keyValueCars[$brand] = total;
}
else{
$keyValueCars[$brand] += total;
}
}
You could use
array_unique(Your_array, SORT_REGULAR);
Please help to solve this issue
i want to change this
[UI Testing] => Array
(
[0] => Array
(
[0] => 0
[1] => 70
)
[1] => Array
(
[0] => 40
[1] => 0
)
)
TO
[UI Testing] => Array
(
[0] => Array
(
[0] => 40
[1] => 70
)
)
Thanks.
Example
$myArray = array();
$myArray[] = array(0,70);
$myArray[] = array(40,0);
$sumArray = array();
foreach ($myArray as $k=>$subArray) {
foreach ($subArray as $id=>$value) {
array_key_exists( $id, $sumArray ) ? $sumArray[$id] += $value : $sumArray[$id] = $value;
}
}
print_r($sumArray);
Output:
Array
(
[0] => 40
[1] => 70
)
Array can be filtered to remove 0 valued indexes and array_reduce to merge array. An example below:
$arr = array('UI Testing' => array( array(0, 70), array(40, 0),) );
$new_arr['UI Testing'] = array_reduce($arr['UI Testing'], function($old, $new) {
return array_filter($new, function( $v ){ return $v > 0 ? $v : null; }) + $old;
}, []);
print '<pre>';
print_r($new_arr);
print '</pre>';
Output
Array
(
[UI Testing] => Array
(
[0] => 40
[1] => 70
)
)
I have three arrays i need to create an array which can be multidimensional.
1st array
Array
(
[0] => Test_One
[1] => Test_two
)
2nd array
Array
(
[0] => www.link.com
[1] => www.link2.com
)
3rd array
Array
(
[0] => Song1
[1] => song2
)
What i want
Array
(
[www.link.com] => Array
(
[0] => Test_one
[1] => Song1
)
[www.link2.com] => Array
(
[0] => Test_two
[1] => Song2
)
)
Assuming that you have same number of elements in all three arrays:
<?php
$arr1 = Array
(
0 => "Test_One",
1 => "Test_two"
);
$arr2 = Array
(
0 => "www.link.com",
1 => "www.link2.com"
);
$arr3 = Array
(
0 => "Song1",
1 => "Song2"
);
$final = []; //for versions below PHP 5.4 use $final = array();
foreach($arr2 as $key=>$value) {
$final[$value] = [$arr1[$key],$arr3[$key]];
}
print_r($final);
will output:
Array
(
[www.link.com] => Array
(
[0] => Test_One
[1] => Song1
)
[www.link2.com] => Array
(
[0] => Test_two
[1] => Song2
)
)
Update: Simplified foreach loop. From Comments #uchiha

Hope this help :)

Trying to alphabetically merge arrays with foreach loop.
<?php
$fruits = array(
'Apple' => array('ids'=>array(1,2)),
'Banana' => array('ids'=>array(3,4)),
'Ananas' => array('ids'=>array(5,6))
);
$result = array();
foreach ($fruits as $name=>$subarr) {
$first_letter = mb_substr($name, 0, 1);
$result[$first_letter] = $subarr;
}
print_r($result);
gives me smth like
Array
(
[A] => Array
(
[ids] => Array
(
[0] => 5
[1] => 6
)
)
[B] => Array
(
[ids] => Array
(
[0] => 3
[1] => 4
)
)
)
instead of smth like
[A] => Array
(
[ids] => Array
(
[0] => 1
[1] => 2
[2] => 5
[3] => 6
)
)
how can I fix it?
You overwrite your result every iteration in this line:
$result[$first_letter] = $subarr;
Just create a new array if the subArray in the result array doesn't exists and merge the ids subArray into your result array.
foreach ($fruits as $name=>$subarr) {
$first_letter = mb_substr($name, 0, 1);
if(!isset($result[$first_letter]))
$result[$first_letter] = [];
$result[$first_letter] = array_merge($result[$first_letter], $subarr["ids"]);
}
Please try to use foreach loop.
$fruits = array(
'Apple' => array('ids'=>array(1,2)),
'Banana' => array('ids'=>array(3,4)),
'Ananas' => array('ids'=>array(5,6))
);
$result = array();
foreach ($fruits as $name=>$subarr) {
$first_letter = mb_substr($name, 0, 1);
foreach($subarr as $key=>$value){
foreach ($value as $gkey => $gvalue) {
$result[$first_letter]['ids'][] = $gvalue;
}
}
}
echo "<pre>";
print_r($result);
Display above code output like below.
Array
(
[A] => Array
(
[ids] => Array
(
[0] => 1
[1] => 2
[2] => 5
[3] => 6
)
)
[B] => Array
(
[ids] => Array
(
[0] => 3
[1] => 4
)
)
)
