I have array data attached in below image and i want to show it exactly like
Array
(
[0] => Array
(
[title] => VALID Act Introduction Advances Diagnostics Regulatory Reform
[link] => https://www.advamed.org/newsroom/press-releases/valid-act-introduction-advances-diagnostics-regulatory-reform
)
[1] => Array
(
[name] => MedTech Fighting Coronavirus on Multiple Fronts
[category] => https://www.advamed.org/newsroom/press-releases/medtech-fighting-coronavirus-multiple-fronts
)
[2] => Array
(
[title] => EPA Ethylene Oxide Value at Odds with Public Health, Best Science
[link] => abc
)
)
Lets say your first data stored in $Title array and second one stored in $Link array. Now populate those in $Data array.
$Data = [];
foreach($Title as $key=>$value){
$Data[] = [
'title'=>$value,
'link'=>$Link[$key]
];
}
in $Data you'll get your desired output.
so finally below is my solution. we just need to sort it out with array map function.
$results = array_map(null , $title, $url);

So I want to delete an array element from a JSON array based on an id in a sub-array. I know it sounds weird. Here's an example of the array. I want to delete the entire array [0] based on the [dealer][id] array where the [id] = 20220 in this example.
Array
(
[results] => Array
(
[offset] => 1
[length] => 15
[data] => Array
(
[0] => Array
(
[dealer] => Array
(
[id] => 20220
[name] => apple
)
)
)
)
}
In reality there are a lot more elements in the [results] array. I'm not sure how to go about it.
Any help is greatly appreciated!
Loop thru data key first then check if dealer id matches the searched id
$id = 20220;
foreach ($array['results']['data'] as $key => $value) {
if ($value['dealer']['id'] == $id) {
unset($array['results']['data'][$key]);
}
}
use array_filter,
$array['results']['data'] = array_filter($array['results']['data'], function($v){return $v['dealer']['id'] != 20220;});

Generate an associative array from an array of rows using one column as keys and another column as values
(3 answers)
Closed 7 months ago.
I have an array of array that looks like this:
Array
(
[0] => Array
(
[id] => I100
[name] => Mary
[gender] => F
)
[1] => Array
(
[id] => I101
[name] => John
[gender] => M
)
[2] => Array
(
[id] => I245
[name] => Sarah
[gender] => F
)
)
I want to set the key of the parent array with the value of id, so the result array looks like this:
Array
(
[I100] => Array
(
[id] => I100
[name] => Mary
[gender] => F
)
[I101] => Array
(
[id] => I101
[name] => John
[gender] => M
)
[I245] => Array
(
[id] => I245
[name] => Sarah
[gender] => F
)
)
If possible I'd like to avoid using an additional loop to go through the array and creating a new array to store each item with the proper key, as the array can have thousands of items.
Thanks in advanced!
Despite your caveat, a loop is the obvious solution:
$newArray = [];
foreach($oldArray as $item)
$newArray[$item['id']] = $item;
If the problem you have is not specifically with a loop, but rather creating a copy of the array is causes excessive memory consumption, then you can edit the array in place, with a for loop:
for($i=0; $i<count($oldArray); $i++){
$oldArray[$oldArray[$i]['id']] = $oldArray[$i];
unset($oldArray[$i]);
}
Note this works because the id elements are alphanumeric strings, if they where simple integars then the above code could overwrite sections.
The only other solution is to build the correct array in the 1st place, in a similar manner.
For example, using PDO::fetch instead of PDO::fetchAll:
//$newArray = $sth->fetchAll(PDO::FETCH_ASSOC);
$newArray = [];
while($row = $sth->fetch(PDO::FETCH_ASSOC))
$newArray[$row['id']] = $row;
You can't overwrite keys while iterating through an array "on the fly". So here is solution with array_map which produces an array with needed structure:
// assuming $arr is your initial array
$result = [];
array_map(function($a) use (&$result){
$result[$a['id']] = $a;
}, $arr);
// $result contains the needed array
You can add needed key during creation of this array.
Note, array_chunk is not my solution (It seems to me).
I have an array of about 150.000 elements
Array
(
[0] => Array
(
[name] => Danilo
[phone] => 33568
)
[1] => Array
(
[name] => Alessandro
[phone] => 392222
)
[2] => Array
(
[name] => Alex
[phone] => 3922
)
[3] => Array
(
[name] => Capa
[phone] => 392
)
)
And so on. I would split this array in several arrays, of (for example) 3.000 elements every one.
I saw array_chunk, but it returns a single array with several subarray.
I need several subarray to store them in a database and elaborate in future.
I'm getting crazy to write a snippet starting from that $temp and divide it into smaller array.
$size_chunks = 1;
$temp = array_chunk($recipients, $size_chunks);
foreach ($temp as $key=>$value)
{
if ($key<$size_chunks)
{
$to_store[] = $temp[$key];
}
//print_r($to_store);
// pseudo sql
// INSERT INTO table (sub_recipient) VALUES ($to_store);
$to_store = array();
}
So, every time that for loop end, reduce temp, store $to_store array and restart for others chunks.
Thank you very much.
PS in my example chunk==1 because starting array is small... ;)
With my example of chunk = 1, I need from starting array this 4 arrays:
Array
(
[0] => Array
(
[name] => Danilo
[phone] => 33568
)
)
Array
(
[0] => Array
(
[name] => Alessandro
[phone] => 39222
)
)
Array
(
[0] => Array
(
[name] => Alex
[phone] => 39222
)
)
Array
(
[0] => Array
(
[name] => Capa
[phone] => 392
)
)
Another explain
1 - With a starting array of 15.000 elements, and chunk of 3.000, I need in output (15.000 / 3.000) = 5 arrays. I will save them in database, so in DB I will have 5 rows (a row for every array).
2 - With a starting array of 4 elements, and chunk of 1, I need in output (4 / 1) = 4 arrays. I will save them in database, so in DB I will have 4 rows (a row for every array).
array_chunks() already does what you want, you just have to save it:
$chunks = array_chunk($array, $size_chunks);
foreach ($chunks as $chunk) {
// save $chunk to your database
}
$recipients = Array(
Array("fdbvfdb","dsacsdcds"),
Array("hrloo","dacdsc"),
Array("dcsdc","adcsd"),
Array("dcsdc","adcsd")
);
$total = count($recipients);//count 150.000 elements
$i=1;
for($i=0;$i<$total;$i++){
$O = array_slice($recipients,$i,1);
print_r($O);
//Your insert/Save code
}
you can use this code there is uses Array_Slice
How do I go about reformatting an object?
Array
(
[0] => Array
(
[user_id] => 5
[first_name] => Ace
[last_name] => Black
)
[1] => Array
(
[user_id] => 6
[first_name] => Gary
[last_name] => Surname
)
[2] => Array
(
[user_id] => 7
[first_name] => Alan
[last_name] => Person
)
)
I need to reformat this so the user_id name is changed to just 'id' and the first_name and last_name values are merged into a single value called 'name' so the final result would look like:
Array
(
[0] => Array
(
[id] => 5
[name] => Ace Black
)
)
You might find array_map useful for this
function fixelement($e)
{
//build new element from old
$n=array();
$n['id']=$e['user_id'];
$n['name']=$e['first_name'].' '.$e['last_name'];
//return value will be placed into array
return $n;
}
$reformatted = array_map("fixelement", $original);
As you can see, one downside is that this approach constructs a second copy of the array, but having written the callback, you can always use it 'in place' like this:
foreach($original as $key=>$value)
{
$original[$key]=fixelement($value);
}
If you want to do it in place:
Foreach that array, set the keys to the values you want, unset the keys for the values you no longer want.
If you want a copy of it:
Foreach that array and ETL (extract, transform, load) into another similar array.
If you need further details to help let me know.
Been kind of stuck on this one for a while now, so any help would be appreciated. I have one array (left) that contains a list of elements, the goal is to sort another arrays (right) keys with the values from the left array.
The left array
Array
(
[0] => ID
[1] => FirstName
[2] => LastName
[3] => Address
)
The right array
Array
(
[0] => Array
(
[FirstName] => Pim
[Address] => Finland
[LastName] => Svensson
[ID] => 3
)
[1] => Array
(
[FirstName] => Emil
[Address] => Sweden
[LastName] => Malm
[ID] => 5
)
)
What I'm trying to accomplish would be similar to this
Array
(
[0] => Array
(
[ID] => 3
[FirstName] => Pim
[LastName] => Svensson
[Address] => Finland
)
Anyone? :)
Oh, I'm running php 5.3, if it helps!
$output = array();
foreach ( $right as $array ) {
foreach ( $left as $field ) {
$temp[$field] = $array[$field];
}
$output[] = $temp;
}
You can use uksort() which lets you sort array keys by a user defined function. E.g.:
function sort_by_array($array) {
// create a sorting function based on the order of the elements in the array
$sorter = function($a, $b) use ($array) {
// if key is not found in array that specifies the order, it is always smaller
if(!isset($array[$a])) return -1;
if($array[$a] > $array[$b]) {
return 1;
}
return ($array[$a] == $array[$b]) ? 0 : -1;
};
return $sorter;
}
// $array contains the records to sort
// $sort_array is the array that specifies the order
foreach($array as &$record) {
uksort($record, sort_by_array(array_flip($sort_array)));
}
I make use of the possibility in 5.3 to define functions dynamically and I use array_flip() to transform:
Array
(
[0] => ID
[1] => FirstName
[2] => LastName
[3] => Address
)
to
Array
(
[ID] => 0
[FirstName] => 1
[LastName] => 2
[Address] => 3
)
This makes it easier to compare the keys later.
You must explode the array
Store the array in a variable like this
$array = Array
(
[0] => Array
(
[ID] => 3
[FirstName] => Pim
[LastName] => Svensson
[Address] => Finland
);
and then explode the array
after exploding the array you will get the parameters of the array seperated then you can use implode function the arrange them in anyorder as you wish
I'd take a step back and look at what you really need to do. The array is associative, so you can access the correct element instantly, right? So you don't really need it to be in order, unless you print output with foreach.
I'd suggest one of the following solutions:
If you need the "right" array to be in key-order, then look at the database query / similar and select the columns in the order you need them.
Foreach person you want to print, look up the order in the "left" array, then print the corresponding value of that key in the "right" array.
Well, your question it's uncommon, usually the associative arrays are used to resolve any problems about "position".
Anyway, there are many way to do what you are looking for what are you looking for.
You can use list() but it's position based:
foreach($oldArray as $o)
{
list($firstName,$lastName,$address,$id)=$oldArray;
$newArray[]=array($id,$firstName,$lastName,$address);
}
But the best way to solve your problem it's fill the array directly in the right order instead of re-sort after :)
