i want when Foreach my Data , For Loop Add Data to Resume Array , exmaple :
Source :
foreach($getusers as $val) // 2record get data from bank But Just 1 record add to Array :(
{
$arr_data =array([
'username'=> $sec->dekey($val->user_username),
'info' => $sec->dekey($val->user_info),
'mobile' => $sec->dekey($val->user_phone),
'code' => $sec->dekey($val->user_code),
'jobside' => $val->user_jobside,
'status' => $val->user_status,
'datetime' => $val->datetime,
'userid' => $val->id,
]);
}
Export :
[{"username":"091584440004","info":"\u062d\u0627\u0646\u06cc\u0647 \u0631\u0648\u062d\u06cc","mobile":"09154479303","code":"091584440004","jobside":"EXPERT","status":"ACTIVE","datetime":"1399/08/13 - 19:26:37","userid":6}]
i want to :
[{"username":"091584440004", info ......]},[{"username":"0921538242",info ......]}, ....
Thanks .
You are overwriting your array instead of adding to it.
To initialise an array, you do:
$arr_data = []
And to append to it:
$arr_data[] = ['new' => 'entry'];
In your example:
$arr_data = [];
foreach($getusers as $val) {
$arr_data[] = [
'username'=> $sec->dekey($val->user_username),
'info' => $sec->dekey($val->user_info),
'mobile' => $sec->dekey($val->user_phone),
'code' => $sec->dekey($val->user_code),
'jobside' => $val->user_jobside,
'status' => $val->user_status,
'datetime' => $val->datetime,
'userid' => $val->id,
];
}
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',
),
)
I have 2 arrays, I want match this arrays and get results with keys.
Can I search in first array with second array keys or match diffrent way?
$boardLists = [
[
'_id' => 'a1a1a1',
'name' => 'Board Name #1',
'code' => 'B1'
],
[
'_id' => 'b2b2b2',
'name' => 'Board Name #2',
'code' => 'B2
]
];
and
$boards = [
'a1a1a1',
'b2b2b2',
'c3c3c3'
];
My result with array_intersect:
array(1) { [0]=> string(6) "a1a1a1" }
My expected result if match 'a1a1a1':
[
'_id' => 'a1a1a1',
'name' => 'Board Name #1',
'code' => 'B1'
],
That I could understand you want to search in the first array according to what you have in the second array, so here is one example:
$boardLists = [
[
'_id' => 'a1a1a1',
'name' => 'Board Name #1',
'code' => 'B1'
],
[
'_id' => 'b2b2b2',
'name' => 'Board Name #2',
'code' => 'B2'
]
];
$boards = [
'a1a1a1',
'b2b2b2',
'c3c3c3'
];
$boardListIds = array_column($boardLists, '_id');
$results = [];
foreach ($boards as $board) {
$find_key = array_search($board, $boardListIds);
if($find_key !== false)
$results[] = $find_key;
}
#printing the results
foreach ($results as $result) {
print_r($boardLists[$result]);
}
There many ways to do it, this is just one. I hope it helps. :)
It would be more efficient to have the array index of your first array the _id. However with the way the array is setup currently you could do:
foreach($boards as $key1=>board){
foreach($boardLists as $key2=>$boardList){
if($boardList['_id']==$key1){
echo $key1 . PUP_EOL;
print_r($boardList);
}
}
}
Try this
$finalArray = array();
foreach($boardLists as $key=>$val):
if(in_array($val['_id'],$boards))
{
$finalArray[] = $val2;
}
endforeach;
I want to know that is there a way to insert certain elements of an array into a new array. I mean I have an array containing 10 objects. Each object has 3 or four fields for example id, name , age , username. now I want to insert the id's of all the objects into the new array with a single call.Is there anyway to do that.
$array = [
[0] => [
id =>
name =>
],
[1] = > [
id =>
name =>
]
]
and so on now I want to insert all the id's of all the object into a new array with a single call. Is there a way to do that?
Use array_map() function.
Here is your solution:-
$ids = array_map( function( $arr ){
return $arr["id"];
}, $arr );
echo '<pre>'; print_r($ids);
A basic foreach loop will do the job just fine
$firstArray = array(
array(
'id' => 1,
'name' => 'abc'
),
array(
'id' => 2,
'name' => 'def'
),
array(
'id' => 3,
'name' => 'gh'
)
);
$onlyIds = array();
$onlyKeys = array();
//To get the array value 'id'
foreach($firstArray as $value){
$onlyIds[] = $value['id'];
}
//To get the array keys
foreach($firstArray as $key => $value){
$onlyKeys[] = $key;
}
You could use array_walk which could be considered a "single call"
$array = array(0 => array('id', 'name', 'age'), 1 => array('id', 'name', 'age'));
array_walk($array, function($item, $key) {
// $key is 0 or 1
// $item is either id, name, age
});
You can use array_column.
$arr = [ ['id' => 1, 'username' => 'a'], ['id' => 2, 'username' => 'b'] ];
$ids = array_column($arr, 'id')
$ids == [1, 2]
I have the following challenging array of associative arrays in php.
array(
(int) 0 => array(
'table' => array(
'venue' => 'venue1',
'name' => 'name1'
)
),
(int) 1 => array(
'table' => array(
'venue' => 'venue1',
'name' => 'name2'
)
),
(int) 2 => array(
'table' => array(
'venue' => 'venue2',
'name' => 'name3'
)
),
(int) 3 => array(
'table' => array(
'venue' => 'venue3',
'name' => 'name4'
)
)
)
I want to extract a list of relevant names out based on the venue. I would like to implement a function ExtractNameArray($venue) such that when $venue=='venue1', the returned array will look like array('name1', 'name2')
I have been cracking my head over this. I am starting with $foreach and am stuck. How can this be done in php? Thank you very much.
first, you have to pass the array with the data to the function
second, the name of the function should start with lower character (php conventions)
try this
function extractNameArray($array, $venue) {
$results = array();
foreach($array as $key=>$value) {
if(isset($value['table']['venue'])&&$value['table']['venue']==$venue) {
isset($value['table']['name']) && $results[] = $value['table']['name'];
}
}
return $results;
}
function ExtractNameArray($venue)
{
$array = array(); // your array
$return_array = array();
foreach($array as $arr)
{
foreach($arr['table'] as $table)
{
if($table['venue'] == $venue)
{
$return_array[]['name'] = $table['name'];
}
}
}
return $return_array;
}
You must define $array with you array. Good Luck
