I have an associative array. I want to remove specific string from whole array items. Here is the structure of my array:
Array
(
[50808] => Array
(
[quantity] => 2
[name] => asv (test)
)
[50809] => Array
(
[quantity] => 2
[name] => 37 (test)
)
[50810] => Array
(
[quantity] => 3
[name] => 38 (test)
)
)
Output i want:
Array
(
[50808] => Array
(
[quantity] => 2
[name] => asv
)
[50809] => Array
(
[quantity] => 2
[name] => 37
)
[50810] => Array
(
[quantity] => 3
[name] => 38
)
)
I know its very simple using loop but i want to do it without loop.
Use array_map function
<?php
$array = Array
(
'50808' => Array
(
'quantity' => 2,
'name' => 'asv (test)',
),
'50809' => Array
(
'quantity' => 2,
'name' => '37 (test)'
),
'50810' => Array
(
'quantity' => 3,
'name' => '38 (test)'
)
);
echo '<pre>';
$new_array = array_map(function($val){
$val['name'] = trim(str_replace('(test)', '', $val['name']));
return $val;
}, $array);
print_r($new_array);
Output:
Array
(
[50808] => Array
(
[quantity] => 2
[name] => asv
)
[50809] => Array
(
[quantity] => 2
[name] => 37
)
[50810] => Array
(
[quantity] => 3
[name] => 38
)
)
Another method can be array_walk function:
array_walk($array, function(&$val){
$val['name'] = trim(str_replace('(test)', '', $val['name']));
});
print_r($array); //out put: desired output

I'm using print_r(array_unique($array, SORT_REGULAR)); on the array below but it does not work.
I'm trying to filter out the redundant data.
Notice that [Order] and its key value pairs are all the same. But [Transaction] and its key value pairs are unique.
I need to get the [Order] element data and combine it with the 3 different [Transaction] elements.
My array
Array
(
[0] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
)
[1] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
)
[2] => Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)
)
The final array I need will look something like this.
Array
(
[Order] => Array
(
[PO] => TR11214
[OrderID] => 242856952012
)
[Transaction] => Array
(
[0] => Array
(
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
[1] => Array
(
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
[2] => Array
(
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)
)
I can flatten the original array and then use array_unique, but wanted to see if there is a better way to accomplish what I need.
my code:
$myarray = array(
0 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11211", "TransactionPrice" => 91.17)
),
1 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11212", "TransactionPrice" => 180.41)
),
2 => array(
"Order" => array("PO" => "TR11214", "OrderID" => 242856952012),
"Transaction" => array("TransPO" => "TR11213", "TransactionPrice" => 209.99)
)
);
print_r(array_unique($myarray, SORT_REGULAR));
If you want to determine how many unique values of the Order element there are in your array, you need to apply array_unique only to the Order elements, which you can do using array_column:
$unique_orders = count(array_unique(array_column($myarray, 'Order'), SORT_REGULAR));
You can process your array using a list of keys which have non-unique values to generate an array, while other keys will have just a single value:
$non_unique_keys = ['Transaction'];
$output = array();
foreach (array_keys($myarray[0]) as $key) {
if (in_array($key, $non_unique_keys)) {
$output[$key] = array_column($myarray, $key);
}
else {
$output[$key] = $myarray[0][$key];
}
}
print_r($output);
Example Output:
Array (
[Order] => Array (
[PO] => TR11214
[OrderID] => 242856952012
)
[Sales Tax] => Array (
[PO] => TR11214
[SalesTaxAmount] => 0
)
[Transaction] => Array (
[0] => Array (
[TransPO] => TR11211
[TransactionPrice] => 91.17
)
[1] => Array (
[TransPO] => TR11212
[TransactionPrice] => 180.41
)
[2] => Array (
[TransPO] => TR11213
[TransactionPrice] => 209.99
)
)
)

array_unique() is intended for single dimensional arrays. If you want to use it on a multi-dimentional array, you should consider using usort() instead. Then you'll need to iterate through the array in reverse manually, searching for duplicates and removing them.
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);
I have an array looks like this:
Array
(
[0] => Array
(
[variant_name] => Green
[product_id] => 2
[variant_id] => 67
[amount] => 1000
)
[1] => Array
(
[variant_name] => Red
[product_id] => 2
[variant_id] => 68
[amount] => 0
)
)
This expected to be like this:
Array (
[2] => array (
[67] => array (
[variant_id] => Green
[amount] => 1000
(
[68] => array (
[variant_id] => Red
[amount] => 0
(
)
Which is group by product_id and then split into arrays group by variant_id.
How can I do that.
Thank you so much.
foreach($values as $product)
{
$newValues[$product["product_id"]][$product["variant_id"]]=
array(
'product_name'=>$product["variant_name"],
'amount'=>$product["amount"]
);
}
Output
Array
(
[2] => Array
(
[67] => Array
(
[product_name] => Green
[amount] => 1000
)
[68] => Array
(
[product_name] => Red
[amount] => 0
)
)
)
Note You have variant_name in your original array and you are using that as variant_id in your output. You can play with indexes in this code. I just used what seemed to match.
A simple foreach loop should suffice. Of course, you need to build them inside a new array. Consider this example: (In your expected example, I think you were referring to variant_name)
$values = array( array( 'variant_name' => 'Green', 'product_id' => 2, 'variant_id' => 67, 'amount' => 1000, ), array( 'variant_name' => 'Red', 'product_id' => 2, 'variant_id' => 68, 'amount' => 0, ), );
$new_values = array();
foreach($values as $key => $value) {
$new_values[$value['product_id']][$value['variant_id']] = array(
'variant_name' => $value['variant_name'],
'amount' => $value['amount'],
);
}
echo '<pre>';
print_r($new_values);
echo '</pre>';
Sample Output
I am trying to form a specific multidimensional array from a mysql result set.
I would like it to look like this:
array(
'product_name' => 'prod_1',
'categories' => array(1,2,3,4)
);
The db result return an array that looks something like this
Array
(
[0] => Array
(
[id] => 1
[product_name] => prod_1
)
[1] => Array
(
[id] => 2
[product_name] => prod_1
)
[2] => Array
(
[id] => 3
[product_name] => prod_1
)
[3] => Array
(
[id] => 4
[product_name] => prod_1
)
As you can see, i would like to group the product name and place the id into another array
Does anyone have any tips on how to do this?
$yourarray = array(array('id'=>1, 'product_name' => 'prod_1'), array('id'=>2, 'product_name' => 'prod_2'),array('id'=>3, 'product_name' => 'prod_3'));
$multiarray = array();
for($i=0; $i<count($yourarray);$i++){
$multiarray['product_name'][] = $yourarray[$i]['product_name'];
$multiarray['product_id'][] = $yourarray[$i]['id'];
}
print_r($yourarray); //original array
print_r($multiarray); //gives you multi array
Something similar to this?
Your original array:
Array
(
[0] => Array
(
[id] => 1
[product_name] => prod_1
)
[1] => Array
(
[id] => 2
[product_name] => prod_2
)
[2] => Array
(
[id] => 3
[product_name] => prod_3
)
)
The result would print:
Array
(
[product_name] => Array
(
[0] => prod_1
[1] => prod_2
[2] => prod_3
)
[product_id] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
Did you try GROUP_CONCAT. It's something like:
SELECT name, GROUP_CONCAT(name) AS friends FROM friendships GROUP BY name;
Have a look for details here: http://forums.mysql.com/read.php?10,287931,287936#msg-287936
$yourarray = array(array('id'=>1, 'product_name' => 'prod_1'), array('id'=>2, 'product_name' => 'prod_1'), array('id'=>3, 'product_name' => 'prod_1'),array('id'=>4, 'product_name' => 'prod_1'));
$multiarray = array();
foreach ($yourarray as $value) {
if(!isset($multiarray['product_name'])) {
$multiarray['product_name'] = $value['product_name'];

This is the tabular representation of the above data which i want to display
centername totalplaced totalworking totaltrained
delhi 8 4 8

Please help me on this.

The difficulty here is that PHP's functions such as array_merge() and array_merge_recursive() will not merge data into numeric keys, but rather will re-key any duplicate numeric key. So for example given two arrays:
array(
'test' => 'abc',
0 => 'xyz'
);
array(
'test' => 'def',
0 => 'uvw'
);
Merging them together with array_merge() will produce an array like:
array(
'test' => 'def',
0 => 'xyz',
1 => 'uvw'
);
So, you need a custom function to be "additive" on any key, regardless of whether it is a string or numeric key. Try this:
function mixed_key_array_merge() {
$args = func_get_args();
$result = array();
foreach ($args as $arg) {
// discard non-array arguments; maybe this could be better handled
if (!is_array($arg)) {
continue;
}
foreach ($arg as $key => $value) {
if (!isset($result[$key])) {
$result[$key] = $value;
} else if (is_array($result[$key])) {
$result[$key] = call_user_func_array('mixed_key_array_merge',array($result[$key],$value));
}
}
}
return $result;
}
