I have an array montant
$montant = array(
"EUR_credit"=>10, "USD_credit"=>20, "EUR_debit"=>30, "JPY_debit"=>20
);
I am trying
$total = array();
foreach ($montant as $key=>$value){
$check_key = substr($key, 0,3);
if(!isset($check_key)){
}
}
echo '<pre>';
print_r($total);
echo '</pre>';
$total = array('EUR'=>array('credit'=10,'debit'=>30),
'USD'=>array('credit'=20,'debit'=>NULL),
'JPY'=>array('credit'=NULL,'debit'=>20),
)
$total = array();
foreach ($montant as $type => $value) {
list($currency, $type) = explode('_', $type);
$total[$currency][$type] = $value;
$total[$currency] += array('credit' => null, 'debit' => null);
}
You have some errors mate inside that $total array definition, corrected:
$total = array
(
'EUR' => array('credit'=>10,'debit'=>30),
'USD' => array('credit'=>20,'debit'=>NULL),
'JPY' => array('credit'=>NULL,'debit'=>20),
);

I am looking to store sum of all keys inside an array here is my example code
<?php
// Sample data
$category = (object) ['category_name' => '32459*1500*lab*1,32460*400*lab*1,32461*600*lab*1'];
// process
$category_sale_data = explode(',', $category->category_name);
foreach ($category_sale_data as $key => $value) {
list($sale_key, $sale_value) = explode('*', $value);
$category->sale_data[$sale_key][] = $sale_value;
//$category->sale_data_sum[$sale_key][] += $sale_value;
}
// display
print_r($category);
getting this output working example -> https://3v4l.org/NAKfb#v7.0.0
Here is expected to get //$category->sale_data_sum[$sale_key][] +=
$sale_value;
I am expected output like this
stdClass Object
(
[category_name] => 32459*1500*lab*1,32460*400*lab*1,32461*600*lab*1
[sale_data] => Array
(
[32459] => Array
(
[0] => 1500
)
[32460] => Array
(
[0] => 400
)
[32461] => Array
(
[0] => 600
)
)
[sale_data_sum] => 2500
)
Simply do this:
$category->sale_data_sum = 0; // initiate key
foreach ($category_sale_data as $key => $value) {
list($sale_key, $sale_value) = explode('*', $value);
$category->sale_data[$sale_key][] = $sale_value;
$category->sale_data_sum += $sale_value; // add each sale value
}
$category = [ 'category_name' => '32459*1500*lab*1,32460*400*lab*1,32461*600*lab*1' ];
// category_name
$result['category_name'] = $category['category_name'];
// sale_data
$splitted = preg_split('/[*,]/', $category['category_name']);
for($i = 0; $i < count($splitted); $i += 4) {
$result['sale_data'][$splitted[$i]] = $splitted[$i + 1];
}
// sale_data_sum
$result['sale_data_sum'] = array_sum($result['sale_data']);
print_r($result);
Try this
<?php
// Sample data
$category = (object) ['category_name' => '32459*1500*lab*1,32460*400*lab*1,32461*600*lab*1'];
// process
$category_sale_data = explode(',', $category->category_name);
foreach ($category_sale_data as $key => $value) {
list($sale_key, $sale_value) = explode('*', $value);
$category->sale_data[$sale_key][] = $sale_value;
//$category->sale_data_sum[$sale_key][] += $sale_value;
}
function sum($carry, $item)
{
$carry += array_values($item)[0];
return $carry;
}
$a = array_reduce(array_values($category->sale_data), "sum");
var_dump($a);
Or
<?php
// Sample data
$category = (object) ['category_name' => '32459*1500*lab*1,32460*400*lab*1,32461*600*lab*1'];
// process
$category_sale_data = explode(',', $category->category_name);
$category->sale_data_sum = null;
foreach ($category_sale_data as $key => $value) {
list($sale_key, $sale_value) = explode('*', $value);
$category->sale_data[$sale_key][] = $sale_value;
$category->sale_data_sum += $sale_value;
}
// display
print_r($category);
I have a lot of array based explode a string like this :
$size = explode(",", $row->SIZE);
$coil_no = explode(",", $row->COIL_NO);
$net = explode(",", $row->NET);
$gross = explode(",", $row->GROSS);
$contract_no = explode(",", $row->CONTRACT_NO);
$location = explode(",", $row->LOCATION);
How can I unite those array into one multidimensional array ?
I have try like this :
foreach ($size as $value) {
foreach ($coil_no as $coil) {
$detail[] = array(
"coil_no" => $coil,
"size" => $value
);
}
}
you know the result the looping is loop weird,
I need more elegant array, like
foreach ($unite_array as $row) :
echo "<tr> $row->size </tr>" ;
endforeach;
What the best way to unite those array ?
You can write your own function which does the grouping on keys as required, see example below:
function array_group(){
if(func_num_args() > 0) {
$params = func_get_args();
$result = array();
foreach($params as $key => $param) {
foreach($param['values'] as $k => $value) {
$result[$k][$param['alias']] = $value;
}
}
return $result;
}
return false;
}
$rows = array_group(
array('alias' => 'size', 'values' => array(1,2,3,4,5)),
array('alias' => 'coil_no', 'values' => array(6,7,8,9,10)),
array('alias' => 'net', 'values' => array(11,12,13,14,15)),
array('alias' => 'gross', 'values' => array(16,17,18,19,20)),
array('alias' => 'contract_no', 'values' => array(21,22,23,24,25)),
array('alias' => 'location', 'values' => array(26,27,28,29,30))
);
print_r($rows);
And you can access it like:
foreach ($rows as $row) :
echo "<tr> {$row['size']} </tr>" ;
endforeach;
I came up with this ugly verbose array (and I have to use it):
$puppy_mother_father_arr = array(
array('46' => array('30','29')),
array('17' => array('30','29')),
array('16' => array('24','29'))
);
How do I simplify it to something like this :
$puppy_mother_father_arr = array(
'46' => array('30','29'),
'17' => array('30','29'),
'16' => array('24','29')
);
I've been stuck a day in here. thanks in advance
$tmp = array();
foreach ($puppy_mother_father_arr as $parent) {
foreach($parent as $key => $nodes) {
$tmp[$key] = $nodes;
}
}
$puppy_mother_father_arr = $tmp;
Would this work?
See the result online
<?php
$puppy_mother_father_arr = array( array('46' => array('30','29')),array('17' => array('30','29')),array('16' => array(24,'29')) );
$list = array();
foreach ($puppy_mother_father_arr as $info)
{
foreach ($info as $key => $value)
{
$list[$key] = $value;
break;
}
}
var_export($list);
$newarray = array();
foreach ($puppy_mother_father_arr as $array) {
foreach ($array as $puppy => $parents) {
$newarray[$puppy] = $parents;
}
}
$puppy_mother_father_arr = $newarray;
key and current could be useful if each array has only one interested key and value:
$result = array();
foreach($puppy_mother_father_arr as $arr) {
$result[key($arr)] = current($arr);
}
var_dump($result);
I need to extract a associative array keys into a string and implode with "/" or any character/symbols.
For eg:
$array = array([key1] =>
array([key11] =>
array([key111] => 'value111',
[key112] => 'value112',
[key113] => 'value113',
),
),
);
I need an output as below array:
array([0] => 'key1/key11/key111',[1] => 'key1/key11/key112', [2] => 'key1/key11/key112');
I've edited an answer given here and came up with the following code.
function listArrayRecursive($someArray, &$outputArray, $separator = "/") {
$iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($someArray), RecursiveIteratorIterator::SELF_FIRST);
foreach ($iterator as $k => $v) {
if (!$iterator->hasChildren()) {
for ($p = array(), $i = 0, $z = $iterator->getDepth(); $i <= $z; $i++) {
$p[] = $iterator->getSubIterator($i)->key();
}
$path = implode($separator, $p);
$outputArray[] = $path;
}
}
}
$outputArray = array();
listArrayRecursive($array, $outputArray);
print_r($outputArray);
Input:
Array
(
[key1] => Array
(
[key11] => Array
(
[key111] => value111
[key112] => value113
[key113] => value113
)
)
)
Output:
Array
(
[0] => key1/key11/key111
[1] => key1/key11/key112
[2] => key1/key11/key113
)
Works for different depth of array:
function getKeys($array, $prefix='', $separator = '/') {
$return = array();
foreach($array as $key => $value) {
if (!is_array($value)) $return[] = $prefix . $key;
else $return = array_merge($return, getKeys($value, $prefix . $key . separator), $separator);
}
return $return;
}
$keys = getKeys($array, '', '#');
See online fiddle http://ideone.com/krU4Xn
you could do something like...
$mapArray = array();
$symbol = '/';
foreach($array as $k =>$v)
foreach($v as $k1 =>$v1)
foreach($v1 as $k2 =>$v2)
$mapArray[] = $k.$symbol.$k1.$symbol.$k2;
also this obviously only works in this particular case, if it needs to be more generic it can be done, but I think this should get you started.
In an array such as the one below, how could I rename "fee_id" to "id"?
Array
(
[0] => Array
(
[fee_id] => 15
[fee_amount] => 308.5
[year] => 2009
)
[1] => Array
(
[fee_id] => 14
[fee_amount] => 308.5
[year] => 2009
)
)
foreach ( $array as $k=>$v )
{
$array[$k] ['id'] = $array[$k] ['fee_id'];
unset($array[$k]['fee_id']);
}
This should work
You could use array_map() to do it.
$myarray = array_map(function($tag) {
return array(
'id' => $tag['fee_id'],
'fee_amount' => $tag['fee_amount'],
'year' => $tag['year']
); }, $myarray);
$arrayNum = count($theArray);
for( $i = 0 ; $i < $arrayNum ; $i++ )
{
$fee_id_value = $theArray[$i]['fee_id'];
unset($theArray[$i]['fee_id']);
$theArray[$i]['id'] = $fee_id_value;
}
This should work.
Copy the current 'fee_id' value to a new key named 'id' and unset the previous key?
foreach ($array as $arr)
{
$arr['id'] = $arr['fee_id'];
unset($arr['fee_id']);
}
There is no function builtin doing such thin afaik.
This is the working solution, i tested it.
foreach ($myArray as &$arr) {
$arr['id'] = $arr['fee_id'];
unset($arr['fee_id']);
}
The snippet below will rename an associative array key while preserving order (sometimes... we must). You can substitute the new key's $value if you need to wholly replace an item.
$old_key = "key_to_replace";
$new_key = "my_new_key";
$intermediate_array = array();
while (list($key, $value) = each($original_array)) {
if ($key == $old_key) {
$intermediate_array[$new_key] = $value;
}
else {
$intermediate_array[$key] = $value;
}
}
$original_array = $intermediate_array;
Converted 0->feild0, 1->field1,2->field2....
This is just one example in which i get comma separated value in string and convert it into multidimensional array and then using foreach loop i changed key value of array
<?php
$str = "abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu
abc,def,ghi,jkl,mno,pqr,stu;
echo '<pre>';
$arr1 = explode("\n", $str); // this will create multidimensional array from upper string
//print_r($arr1);
foreach ($arr1 as $key => $value) {
$arr2[] = explode(",", $value);
foreach ($arr2 as $key1 => $value1) {
$i =0;
foreach ($value1 as $key2 => $value2) {
$key3 = 'field'.$i;
$i++;
$value1[$key3] = $value2;
unset($value1[$key2]);
}
}
$arr3[] = $value1;
}
print_r($arr3);
?>
I wrote a function to do it using objects or arrays (single or multidimensional) see at https://github.com/joaorito/php_RenameKeys.
Bellow is a simple example, you can use a json feature combine with replace to do it.
// Your original array (single or multi)
$original = array(
'DataHora' => date('YmdHis'),
'Produto' => 'Produto 1',
'Preco' => 10.00,
'Quant' => 2);
// Your map of key to change
$map = array(
'DataHora' => 'Date',
'Produto' => 'Product',
'Preco' => 'Price',
'Quant' => 'Amount');
$temp_array = json_encode($original);
foreach ($map AS $k=>$v) {
$temp_array = str_ireplace('"'.$k.'":','"'.$v.'":', $temp);
}
$new_array = json_decode($temp, $array);
Multidimentional array key can be changed dynamically by following function:
function change_key(array $arr, $keySetOrCallBack = [])
{
$newArr = [];
foreach ($arr as $k => $v) {
if (is_callable($keySetOrCallBack)) {
$key = call_user_func_array($keySetOrCallBack, [$k, $v]);
} else {
$key = $keySetOrCallBack[$k] ?? $k;
}
$newArr[$key] = is_array($v) ? array_change_key($v, $keySetOrCallBack) : $v;
}
return $newArr;
}
Sample Example:
$sampleArray = [
'hello' => 'world',
'nested' => ['hello' => 'John']
];
//Change by difined key set
$outputArray = change_key($sampleArray, ['hello' => 'hi']);
//Output Array: ['hi' => 'world', 'nested' => ['hi' => 'John']];
//Change by callback
$outputArray = change_key($sampleArray, function($key, $value) {
return ucwords(key);
});
//Output Array: ['Hello' => 'world', 'Nested' => ['Hello' => 'John']];
I have been trying to solve this issue for a couple hours using recursive functions, but finally I realized that we don't need recursion at all. Below is my approach.
$search = array('key1','key2','key3');
$replace = array('newkey1','newkey2','newkey3');
$resArray = str_replace($search,$replace,json_encode($array));
$res = json_decode($resArray);
On this way we can avoid loop and recursion.
Hope It helps.
