//Get all id and name from db
foreach($fetchall as $all) {
$tobeappended = array (
'id' => $all['id'],
'name' => $all['name']
);
}
Append to
$myarray = array(
//other definition here....
'animals' => $tobeappended
);
I want to append all data from the array in foreach in the following format
[array('id' => '1','name'=>'cow'),array('id' => '2','name'=>'cat')]
Is there any way to do this
$myarray = [
'animals' => []
]
//Get all id and name from db
foreach($fetchall as $all) {
$myarray['animals'][] = [
'id' => $all['id'],
'name' => $all['name']
];
}
I need to perform iterated explosions on values in one column of my two dimensional array, then re-group the data to flip the relational presentation from "tag name -> video id" to "video id -> tag name".
Here is my input array:
$allTags = [
[
"name" => "TAG-ONE",
"video" => "64070,64076,64110,64111",
],
[
"name" => "TAG-TWO",
"video" => "64070,64076,64110,64111",
],
[
"name" => "TAG-THREE",
"video" => "64111",
]
];
I want to isolate unique video ids and consolidate all tag names (as comma-separayed values) that relate to each video id.
Expected output:
$allTagsResult = [
[
"name" => "TAG-ONE,TAG-TWO",
"video" => "64070",
],
[
"name" => "TAG-ONE,TAG-TWO",
"video" => "64076",
],
[
"name" => "TAG-ONE,TAG-TWO",
"video" => "64110",
],
[
"name" => "TAG-ONE,TAG-TWO,TAG-THREE",
"video" => "64111",
],
];
Somehow I did it by checking the value using nested loops but I wish to know if you guys can suggest any shortest method to get the expected output.
If you want to completely remove foreach() loops, then using array_map(), array_walk_recursive(), array_fill_keys() etc. can do the job. Although I think that a more straightforward answer using foreach() would probably be faster, but anyway...
$out1 = array_map(function ($data) {
return array_fill_keys(explode(",", $data['video']), $data['name']); },
$allTags);
$out2 = [];
array_walk_recursive( $out1, function ( $data, $key ) use (&$out2) {
if ( isset($out2[$key])) {
$out2[$key]['name'] .= ",".$data;
}
else {
$out2[$key] = [ 'name' => $data, 'video' => $key ];
}
} );
print_r($out2);
will give...
Array
(
[64070] => Array
(
[name] => TAG-ONE,TAG-TWO
[video] => 64070
)
[64076] => Array
(
[name] => TAG-ONE,TAG-TWO
[video] => 64076
)
[64110] => Array
(
[name] => TAG-ONE,TAG-TWO
[video] => 64110
)
[64111] => Array
(
[name] => TAG-ONE,TAG-TWO,TAG-THREE
[video] => 64111
)
)
if you want to remove the keys, then
print_r(array_values($out2));
The code could be compressed by piling all of the code onto single lines, but readability is more useful sometimes.
Another method if you don't like looping:
$video_ids = array_flip(array_unique(explode(",",implode(",",array_column($allTags,'video')))));
$result = array_map(function($id){
return ['name' => '','video' => $id];
},array_flip($video_ids));
array_walk($allTags,function($tag_data) use (&$result,&$video_ids){
$ids = explode(",",$tag_data['video']);
foreach($ids as $id) $result[$video_ids[$id]]['name'] = empty($result[$video_ids[$id]]['name']) ? $tag_data['name'] : $result[$video_ids[$id]]['name'] . "," . $tag_data['name'];
});
Demo: https://3v4l.org/vlIks
Below is one way of doing it.
$allTags = [
'0' => [
"name" => "TAG-ONE",
"video" => "64070,64076,64110,64111",
],
'1' => [
"name" => "TAG-TWO",
"video" => "64070,64076,64110,64111",
],
'2' => [
"name" => "TAG-THREE",
"video" => "64111",
]
];
$allTagsResult = array();
$format = array();
foreach( $allTags as $a ) {
$name = $a['name'];
$videos = explode(',', $a['video']);
foreach( $videos as $v ) {
if( !isset( $format[$v]) ) {
$format[$v] = array();
}
$format[$v][] = $name;
}
}
foreach( $format as $video => $names) {
$allTagsResult[] = array('name' => implode(',', $names), 'video' => $video);
}
echo '<pre>';
print_r($allTagsResult);
die;

I am typically in favor of functional style coding, but for this task I feel it only serves to make the script harder to read and maintain.
Use nested loops and explode the video strings, then group by those video ids and concatenate name strings within each group. When finished iterating, re-index the array.
Code: (Demo)
$result = [];
foreach ($allTags as $tags) {
foreach (explode(',', $tags['video']) as $id) {
if (!isset($result[$id])) {
$result[$id] = ['video' => $id, 'name' => $tags['name']];
} else {
$result[$id]['name'] .= ",{$tags['name']}";
}
}
}
var_export(array_values($result));
Output:
array (
0 =>
array (
'video' => '64070',
'name' => 'TAG-ONE,TAG-TWO',
),
1 =>
array (
'video' => '64076',
'name' => 'TAG-ONE,TAG-TWO',
),
2 =>
array (
'video' => '64110',
'name' => 'TAG-ONE,TAG-TWO',
),
3 =>
array (
'video' => '64111',
'name' => 'TAG-ONE,TAG-TWO,TAG-THREE',
),
)
What I'm trying to accomplish is to write a html string in a controller with array values being looped in it. So for example;
$content = "Your store, at location A, has these items added to them". add array loop here. "Do take note!";
My array would be as such
array (
0 =>
array (
'id' => '5db29b6d31c391731239bbdf',
'name' => 'Diamond bracelet (sample)',
'tags' =>
array (
0 => 'female',
1 => 'jewelry',
),
'category' => 'Accessories',
'sku' => '1029EHW',
'priceType' => 'Fixed',
'unitPrice' => 190,
'cost' => 90,
'trackStockLevel' => true,
'isParentProduct' => false,
),
1 =>
array (
'id' => '5db29b6d31c391731239bbdb',
'name' => 'Long-sleeved shirt(sample)(M)',
'tags' =>
array (
0 => 'tops',
1 => 'cotton',
),
'category' => 'Women\'s Apparel',
'sku' => 'ABC1234-M',
'priceType' => 'Fixed',
'unitPrice' => 47.170000000000002,
'cost' => 20,
'trackStockLevel' => true,
'isParentProduct' => false,
'parentProductId' => '5db29b6d31c391731239bbd4',
'variationValues' =>
array (
0 =>
array (
'variantGroupId' => '5db29b6d31c391731239bbd5',
'value' => 'M',
),
),
),
)
note that the array can have many instances of product_name and sku, or can have none.
How do i populate this in my string to be like;
$content = "Your store, at location A, has these items added to them, 1) asd, 2)def, 3)asf . Do take note!
Try this, I've used \sprintf for ease, check if the output serves your purpose.
<?php
function stringMethod(): string
{
$count = 0;
$arrayString = [];
$array = [['product_name' => 'abc', 'product_sku' => 'def'],['product_name' => 'abc', 'product_sku' => 'asd']];
foreach ($array as $value){
$count++;
$arrayString[] = sprintf('%s)%s', $count, $value['product_sku']);
}
$string = \implode(',', $arrayString);
return \sprintf("Your store, at location A, has these items added to them %s Do take note!", $string);
}
echo stringMethod();
Hope this will help you. try to do it in less number of lines
$content = "Your store, at location A, has these items added to them, ";
$productArray = array (0 => array ('id' => '5db29b6d31c391731239bbdf','name' => 'Diamond bracelet (sample)','tags' => array (0 => 'female',1 => 'jewelry',),'category' => 'Accessories','sku' => '1029EHW','priceType' => 'Fixed','unitPrice' => 190,'cost' => 90,'trackStockLevel' => true,'isParentProduct' => false,),1 => array ('id' => '5db29b6d31c391731239bbdb','name' => 'Long-sleeved shirt(sample)(M)','tags' => array (0 => 'tops',1 => 'cotton',),'category' => 'Women\'s Apparel','sku' => 'ABC1234-M','priceType' => 'Fixed','unitPrice' => 47.170000000000002,'cost' => 20,'trackStockLevel' => true,'isParentProduct' => false,'parentProductId' => '5db29b6d31c391731239bbd4','variationValues' => array (0 => array ('variantGroupId' => '5db29b6d31c391731239bbd5','value' => 'M'))));
foreach ($productArray as $key => $product) {
$content .= ($key+1).') '.$product['name'];
if (count($productArray)-1!=$key) {
$content .= ', ';
}
}
$content .= ". Do take note!";
$content = "Your store, at location A, has these items added to them,". $this->getItemList($collection) .". Do take note!"
# Somewhere else in the controller
protected function getItemList(Collection $collection): string
{
return $collection->pluck('name')
->merge($collection->pluck('sku'))
->map(function($item, $key) {
return ($key + 1) . ') ' . $item;
})
->implode(', ');
}
An easy solution would be
$content = "Your store, at location A, has these items added to them";
$array = array(0=>["product_name" => "abc", "product_sku" => "def"], 1=>['product_name' => 'kdkf', 'product_sku'=> 'ljbkj']);
for($i = 0; $i<count($array); $i++){
$content .= ($i+1).") ".$array[$i]['product_name].' '.$array[$i]['product_sku'].', ';
}
$content .= "Do take note.";
This way you're just constantly concatonating the string value in separate parts instead of trying to inject it in the middle of the parent string.
not tested, may be syntax errors
I'm trying to extract data from a multidimensional array and then putting into one of my own so that I can load it into my database.
Source:
array( "ListOrdersResult" =>
array ( "Orders" =>
array( "Order" =>
array( [0] => {
"Title" => $productTitle,
"customer_name" => $customerName,
"customer_id" => $customerId,
"random_info" => $randomInfo
},
[1] => {
"Title" => $productTitle,
"customer_name" => $customerName,
"customer_id" => $customerId,
"random_info" => $randomInfo
}
)
)
)
To do this, I'm cycling through it like this - I have no issues with extracting data.
My code:
$count = count($listOrderArray['ListOrdersResult']['Orders']['Order']);
//Cycle through each Order to extract the data I want
for($i = 0; $count > $i; $i++) {
$baseArray = $listOrderArray['ListOrdersResult']['Orders']['Order'][$i];
foreach($baseArray as $key => $value) {
if($key == "Title" || $key == "customer_id") {
//ADD TO multidimensional array
}
}
}
How I'm trying to structure it.
array( [0] => {
array(
"Title" => $title,
"customer_id" => $customer_id
},
[1] => {
"Title" => $nextTitle,
"customer_id" => $next_customer_id
}
);
The ultimate goal is to make it easier to load the information into the database by gathering the data by record and then loading it to the database rather than loading by creating an new record and then coming back and modifying that record. To me that seems like it would take more resources and has a higher chance of inconsistent data, but I'm new so I could be wrong.
Any help would be greatly appreciated.
You only have to unset keys you don't want:
$result = array_map(function ($i) {
unset($i['customer_name'], $i['random_info']);
return $i;
}, $listOrderArray['ListOrdersResult']['Orders']['Order']);
More about array_map
Or you also can select the keys you want:
$result = array_map(function ($i) {
return ['Title' => $i['Title'], 'customer_id' => $i['customer_id']];
}, $listOrderArray['ListOrdersResult']['Orders']['Order']);
About your code and question:
$count = count($listOrderArray['ListOrdersResult']['Orders']['Order']);
//Cycle through each Order to extract the data I want
for($i = 0; $count > $i; $i++) {
There's no reason to use a count and a for loop, use foreach.
array( [0] => {
array(
"Title" => $title,
"customer_id" => $customer_id
},
[1] => {
"Title" => $nextTitle,
"customer_id" => $next_customer_id
}
);
doesn't make sense, what are these curly brackets? You should write it like this if you want to be understood:
array(
[0] => array(
"Title" => "fakeTitle0",
"customer_id" => "fakeCustomerId0"
),
[1] => array(
"Title" => "fakeTitle1",
"customer_id" => "fakeCustomerId1"
)
);
You have this initial variable.
$listOrderArray = array(
"ListOrdersResult" => array(
"Orders" => array(
"Order" => array(
0 => array(
"Title" => "productTitle",
"customer_name" => "customerName",
"customer_id" => "customerId",
"random_info" => "randomInfo",
),
1 => array(
"Title" => "productTitle",
"customer_name" => "customerName",
"customer_id" => "customerId",
"random_info" => "randomInfo",
),
)
)
)
);
The only thing you should do is to remove the inner array from the three outer arrays.
Here is the solution:
$orders = $listOrderArray['ListOrdersResult']['Orders']['Order'];

How can I store in Session Array Variable in a MySQL database ?
Just make sure that you assign the array the way you assign a normal value and then store the array in your database.
$_SESSION['dArray'] = $strRTypeArr;
//for example:
$strRTypeArr[0][0] = array (
'myRoomSq' => 2.5,
'roomSeq' => "test this",
'adults' => true,
'child' => 5,
'childAges' => "test"
);
$strRTypeArr[0][1] = array (
'myRoomSq' => 3.5,
'roomSeq' => "this is another test",
'adults' => false,
'child' => 6,
'childAges' => "test"
);
$_SESSION['dArray'] = $strRTypeArr;
echo "<pre>";
print_r($_SESSION['dArray']);
echo "</pre>";
//Store this $_SESSION['dArray'] in your database
You can also use json_encode($_SESSION['dArray']); to store your array in the database.
