I have two arrays
$array1 = array(
0 => array(
'user' => 'user0',
'id' => 'id0'
),
1 => array(
'user' => 'user1',
'id' => 'id1'
),
2 => array(
'user' => 'user2',
'id' => 'id2'
)
);
$array2 = array(
0 => array(
'emp' => 'emp0',
'id' => 'id3'
),
1 => array(
'emp' => 'emp1',
'id' => 'id1'
),
2 => array(
'emp' => 'emp2',
'id' => 'id2'
)
);
i need to loop array 2 first an d give input of id from array1 to the array 1 and search whether the value of id1 from arr1 exists in array2
Maybe this could work? (If I understood your question correctly)
$id_arr = array();
$final_arr = array();
checkArray($array1, $id_arr, $final_arr);
checkArray($array2, $id_arr, $final_arr);
function checkArray($arr, &$id_arr, &$final_arr) {
foreach ($arr as $key => $value) {
if (!in_array($value['id'], $id_arr)) {
$id_arr[] = $value['id'];
$final_arr[] = $value;
}
}
}
var_dump($final_arr);

Closed 1 year ago.
can someone explain me how to multiply the value from this code? i tried but still cant solve this
arrayK(
0 => array(
'name'=> AA,
'value' => 2.00,
),
1 => array(
'name' => AA,
'value' => 1.82,
),
2 => array(
'name' => BB,
'value' => 2.20,
),
3 => array(
'name' => AA,
'value' => 4.20,
),
4 => array(
'name' => BB,
'value' => 4.20,
),
);
the answer should back to array with value already multiply where it has same name
newArray(
0 => array(
'name'=> AA,
'value' => ...,
),
1 => array(
'name' => BB,
'value' => ....,
),
);
To multiply duplicate value and get new array:
$array=array(
0 => array(
'name'=> AA,
'value' => 2.00,
),
1 => array(
'name' => AA,
'value' => 1.82,
),
2 => array(
'name' => BB,
'value' => 2.20,
),
3 => array(
'name' => AA,
'value' => 4.20,
),
4 => array(
'name' => BB,
'value' => 4.20,
),
);
$result = array();
foreach ($array as $val) {
if (!isset($result[$val['name']]))
$result[$val['name']] = $val;
else
$result[$val['name']]['value'] *= $val['value'];
}
$result = array_values($result); // reindex array
echo "<pre>";
print_r($result);
You can try following solution.
$arrayK = array(
0 => array(
'name'=> "AA",
'value' => 2.00,
),
1 => array(
'name' => "AA",
'value' => 1.82,
),
2 => array(
'name' => "BB",
'value' => 2.20,
),
3 => array(
'name' => "AA",
'value' => 4.20,
),
4 => array(
'name' => "BB",
'value' => 4.20,
),
);
$temp = array_values((array_unique(array_column($arrayK, 'name'))));
$arrayY = [];
for( $i = 0; $i < count($temp); $i++ ) {
foreach( $arrayK as $key => $val ) {
if( $val['name'] == $temp[$i] ) {
$arrayY[$i] = [
'name' => $val['name'],
'value' => isset($arrayY[$i]['value']) ? $val['value'] * $arrayY[$i]['value'] : $val['value']
];
}
}
}
print_r($arrayY);
Out put
Array
(
[0] => Array
(
[name] => AA
[value] => 15.288
)
[1] => Array
(
[name] => BB
[value] => 9.24
)
)
You can play with the code Here
Let's say i have an array like this:
$array = array(
0 =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
1=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
21 =>
array(
'value' => 'adresa#gmail.com' ,
'name' => 'name1`' ),
23 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
24 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
26 =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
27 =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);
I want to know if exists duplicated value in array with key 'value' I know how to do this if i want a specified value but general no. The result must be an array with no duplicated values(eg:
$array = array(
0 =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
1=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
23 =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
26 =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
27 =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);`
Please help me.
This is my try
function has_dupes($array){
$dupe_array = array();
foreach($array as $val){
if(++$dupe_array[$val] > 1){
return true;
}
}
return false;
}
Try this way:
$array = array(
'0' =>
array (
'value' => '1' ,
'name' => 'dasdfa sadfa' ),
'1'=> Array (
'value' => 'adresa#gmail.com' ,
'name' => 'd2' ),
'21' =>
array(
'value' => 'adresa#gmail.com' ,
'name' => 'name1`' ),
'23' =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
'24' =>
array(
'value' => 'popescu.catalina#gmail.com' ,
'name' => 'POPESCU CATALINA' ),
'26' =>
array(
'value' => 'ricardo.ramos#amadeus.com',
'name' => '43414 Test01'),
'27' =>
array(
'value' => 'sta3no213123ct3av#yahoo.com',
'name' => 'oct oct' )
);
$array = array_map("unserialize", array_unique(array_map("serialize", $array)));
$result = array_unique($array);
print_r($result);
And if you want to store all unique data in one array do it like this:
//declare $array
$unique_array = array();
foreach ($array as $key => $type) {
foreach($type as $vale => $name) {
if ($vale == 'value') {
//echo $name . '<br>';
array_push($unique_array, $name);
}
}
}
$result = array_unique($unique_array);
foreach ($result as $res) {
echo $res . '<br>';
}
Try this
$values = array_map("unserialize", array_unique(array_map("serialize", $array)));
foreach ($values as $key => $value)
{
if ( is_array($value) )
{
$values[$key] = $value;
}
}
print_r($values);
$unique_data = array(); // the result array
$duplicate_data = array();
$seen = array();
foreach ($array as $key => $arr) {
$value = $arr['value'];
if (!isset($seen[$value])) {
$seen[$value] = '';
$unique_data[$key] = $arr;
} else {
$duplicate_data[$key] = $arr; // optional
}
}
unset($seen); // optional in function scope
I have this php array X.
X= array(
'Parent' => array(
'title' => '123',
)
)
I have this php array Y.
Y = array(
'Parent' => array(
'id' => '16',
'title' => 'T1',
),
'Children' => array(
(int) 0 => array(
'id' => '8',
'serial_no' => '1',
),
(int) 1 => array(
'id' => '9',
'serial_no' => '2',
),
(int) 2 => array(
'id' => '14',
'serial_no' => '6',
)
)
)
I want to copy the Children of array Y to the parent of array X to form array Z such that it looks like this;
Z= array(
'Parent' => array(
'title' => '123',
)
'Children' => array(
(int) 0 => array(
'serial_no' => '1'
),
(int) 1 => array(
'serial_no' => '2'
),
(int) 2 => array(
'serial_no' => '6'
)
)
)
Please note that the id key-value pair was removed from the Children of array Y.
I wrote some code of my own.
$Z = array();
$i=0;
foreach($Y as $temp)
{
$Z['Children'][$i] = $temp['Children'][$i];
unset($Z['Children'][$i]['id'];
$i++;
}
$Z['Parent']=$temp['Parent'];
Unfortunately, there is an undefined index error. How can this be done in php? Forget about my code if there are better approaches.
Actually your approach works too, but you need to iterate over sub-array:
$Z = array();
$i=0;
foreach($Y['Children'] as $temp)
{
$Z['Children'][$i] = $temp;
unset($Z['Children'][$i]['id'];
$i++;
}
or what I may do:
$Z = $X;
$Z['Children'] = array();
foreach ( $Y['Children'] as $child ) {
$Z['Children'][] = array(
'serial_no' => $child['serial_no'],
);
}
You can do like.
$Z = array();
foreach($Y['Children'] as $temp)
{
$Z['Children'][] = array('serial_no' => $temp['serial_no']);
}
$Z['Parent']=$X['Parent'];
I have this php associative array which I created from a MySQL query. It looks like this;
array(
(int) 0 => array(
'items' => array(
'index_no' => '1'
),
(int) 0 => array(
'NumItems' => '2'
)
),
(int) 1 => array(
'items' => array(
'index_no' => '2'
),
(int) 0 => array(
'NumItems' => '3'
)
)
It looks unnecessarily complicated. I would like to simplify it to look something like this;
array(
(int) 0 => array(
'index_no' => '1',
'NumItems' => '2'
)
),
(int) 1 => array(
'index_no' => '2',
'NumItems' => '3'
)
)
How can this be done in php? I have been stuck on this problem for some time. I will post my answer if I have it. I would appreciate it if someone could give me some starting point. Thank you very much.
You can try this out:
$tempArray = array(
(int) 0 => array(
'items' => array(
'index_no' => '1'
),
(int) 0 => array(
'NumItems' => '2'
)
),
(int) 1 => array(
'items' => array(
'index_no' => '2'
),
(int) 0 => array(
'NumItems' => '3'
)
));
$newArray = array();
$i=0;
foreach($tempArray as $temp) {
$newArray[$i]['index_no'] = $temp['items']['index_no'];
$newArray[$i]['NumItems'] = $temp[0]['NumItems'];
$i++;
}
print "<pre>";
print_r($newArray);
try this
<?php $res=array(array('item'=>1,'number'=>5),array('item'=>2,'number'=>56));
$final_array =array();
$i=0;
foreach ($res as $val)
{
foreach($val as $key=>$val2)
{
$final_array[$i][$key] = $val2;
}$i++;
}
print_r($final_array);
?>
Here is solution for you.
$diffArray = array(
(int) 0 => array(
'items' => array(
'index_no' => '1'
),
(int) 0 => array(
'NumItems' => '2'
)
),
(int) 1 => array(
'items' => array(
'index_no' => '2'
),
(int) 0 => array(
'NumItems' => '3'
)
));
print_r($diffArray);
$getArray = array();
foreach ($diffArray as $simArray) {
$getArray['index_no'][] = $simArray['items']['index_no'];
$getArray['NumItems'][]= $simArray[0]['NumItems'];
}
print_r($getArray);
$newArray = array();
foreach ($array as $items) {
$temp = array('index_no' => $items['index_no']);
$temp = array_merge($temp, $items[0]);
$newArray[] = $temp;
}
it will add all the keys to the array under index - 0
I have the following array of associative arrays.
$result = array(
(int) 0 => array(
'name' => 'Luke',
'id_number' => '1111',
'address' => '1544addr',
'time_here' => '2014-04-12 13:07:08'
),
(int) 1 => array(
'name' => 'Sam',
'id_number' => '2222',
'address' => '1584addr',
'time_here' => '2014-04-12 14:15:26'
I want to remove selected elements from this array such that it will look like this;
array(
(int) 0 => array(
'name' => 'Luke',
'id_number' => '1111'
),
(int) 1 => array(
'name' => 'Sam',
'id_number' => '2222',
This is the code I wrote;
foreach($result as $value)
{
unset($value('address') );
unset($value('time_here') );
}
When I run the code, Apache web server crashed.
Can the smarter members point out what did I do wrong? Thank you very much.
Array notation is wrong, use this;
$finalResult = array();
foreach($result as $value)
{
unset($value['address'] );
unset($value['time_here'] );
$finalResult[] = $value;
}
Here is a working demo: Demo
That is because you are not accessing array correctly. Use square bracket insted of round brackets :
foreach($result as $value)
{
unset($value['address'] );
unset($value['time_here'] );
}
