Convert multidimensional array into single array [duplicate]

Closed 5 years ago.
Hi i got this array from my database.
array (size=4)
0 =>
array (size=1)
0 =>
array (size=1)
'email_1' => string 'denise#aaa.com' (length=18)
1 =>
array (size=1)
0 =>
array (size=1)
'email_1' => string 'denise#aaa.com' (length=18)
And i need to do get like this
array (size=4)
0 =>
array (size=1)
email_1' => string 'denise#aaa.com' (length=18)
1 =>
array (size=1)
'email_1' => string 'denise#aaa.com' (length=18)
I tried with array_merge and all. But no idea how to archive this?
Do it like below:-
$final_array = array();
foreach($original_array as $key=>$val){
$final_array[$key][] = $val[0]['email_1'];
}
print_r($final_array);
Output:-https://eval.in/848213
In php it is possible to do like this
foreach ($yourArray as $arr){
$result[] = $arr[0];
}
You can get also your desired output like this:
$result = array_map('array_collapse',$yourArray);
For this just assign like this to its first element.
foreach($yourArray as $array){
$array = $array[0];
}

How to filter an array by a condition
(9 answers)
Closed 2 years ago.
At first, im beginner.
I want to push elements from array to another array what does not contain numbers
I have an array1:
0 => string '142221A' (length=7)
1 => string 'hOUSES' (length=6)
2 => string 'bOOKS' (length=5)
3 => string 'sHOES' (length=5)
4 => string '92921' (length=5)
5 => string '12231' (length=5)
6 => string 'cARS' (length=4)
7 => string 'tOYS' (length=4)
The output i want like this, array2:
0 => string 'hOUSES' (length=6)
1 => string 'bOOKS' (length=5)
2 => string 'sHOES' (length=5)
3 => string 'cARS' (length=4)
4 => string 'tOYS' (length=4)
I dont want a solution, i want the way for it.
in PHP you can use is_numeric() method to check the string is a just a numeric or not as the following way:
$elements = ['142221A','hOUSES','bOOKS','sHOES','92921','12231','cARS','tOYS'];
$string_array = [];
foreach ($elements as $element) {
if(!is_numeric($element)) {
array_push($string_array, $element);
}
}
print_r($string_array);
but if you want to filter elements of an array to just have the elements that don't have any numeric value inside of it use the following way:
$elements = ['142221A','hOUSES','bOOKS','sHOES','92921','12231','cARS','tOYS'];
$just_string = [];
foreach ($elements as $element) {
//it will check for the element which has a digit number inside of it or not
//if it doesn't contain any number then it will be added to new array
if(preg_match('~[0-9]~', $element) != 1){
array_push($just_string, $element);
}
}
print_r($just_string);
I am trying to array_merge id’s from one array into another, it’s merging but putting the new values on a new array line:
IDs to be added: $attachment_ids
array (size=2)
0 => string '2620' (length=4)
1 => string '2621' (length=4)
IDs which already exist and will be added to: $existing_data
array (size=1)
0 => string '2589,2561,2432,2422' (length=19)
result of my array_merge:
$merged_data = array_merge($attachment_ids, $existing_data);
is
array (size=3)
0 => string '2620' (length=4)
1 => string '2621' (length=4)
2 => string '2589,2561,2432,2422' (length=19)
My expected result is:
array (size=1)
0 => string '2620,2621,2589,2561,2432,2422'
If you just need the 1 string with all of the values, you could use implode() with the result you have so far...
$merged_data = [ implode(",", $merged_data) ];
Shortly array merge with array_map
$result=array_map(null,$array1,$array2);
array_merge() requires 2 arrays. The existing data is all in a string. With explode, this data can be converted into an array. With implode() a list is created after array_merge().
$attachment_ids = ['2620','2621'];
$existing_data = ['2589,2561,2432,2422'];
$existing_data = explode(',',$existing_data[0]);
$result = [implode(',',array_merge($attachment_ids,$existing_data))];
//$result: array(1) { [0]=> string(29) "2620,2621,2589,2561,2432,2422" }
Update
Alternatively, strings can be chained manually.
$result = [implode(',',$attachment_ids).','.$existing_data[0]];

How to extract and access data from JSON with PHP?

How can I access an array/object?
(6 answers)
Closed 5 years ago.
Need help and advice on json_decode() in PHP. I am working on a CURL operation for an API call and the return result is a JSON. What is the syntax that I need to access the field pgid?
CURL Operation
$output = curl_exec($ch);
$rslt = json_decode($output, true);
var_dump($rslt);
The var_dump() output
array (size=1)
'protection-groups' => array (size=3)
0 => array (size=2)
'ppsDropped' => float 0
'pgid' => int 13
1 => array (size=2)
'ppsDropped' => float 7.9957930115316
'pgid' => int 18
2 => array (size=2)
'ppsDropped' => float 5302.7606884163
'pgid' => int 19
Try like this :
$output = curl_exec($ch);
$rslt = json_decode($output, true);
$idsArray = array();
foreach($rslt['protection-groups'] as $key => $value){
$pgId = $value['pgid'];
echo $pgId;
//Or in case you need all the PGID's in array then :
array_push($idsArray,$value['pgid']);
}
print_r($idsArray);
exit();
try below code that will loop through and get all pgid
foreach($rslt['protection-groups'] as $group)
{
echo $group['pgid'];
}

Is there a function to extract a 'column' from an array in PHP?

is it possible to convert it to single array without the key 'entity_id' without a loop?
array
0 =>
131813
1 =>
213808
2 =>
712885
I have tried this one :
call_user_func_array('array_merge', $array)
but somehow is only returning 1 element
UPDATE:
here are the benchmark results from the given answers to this question:
php version > 5.6
array_column: 0.20802903175354
foreach: 0.46231913566589
array_map: 1.021989107132
php version > 7
array_column: 0.079965829849243
foreach: 0.15323305130005
array_map: 0.28970503807068
This is also possible with array_column.
$result = array_column($your_array, 'entity_id');
You can do this very easily with array_map like this:
$result = array_map(function($value) {
return $value['entity_id'];
}, $originalArray);
Working example: https://3v4l.org/JOEMI
Of course you could also do it with a foreach loop:
$result = [];
foreach($originalArray AS $entity) {
$result[] = $entity['entity_id'];
}
Working example: https://3v4l.org/9J5XH
I prefer the first option personally.
Update: the accepted answer is clearly the best way. Do that! Leaving this here for comparison.

How to filter an associative array comparing keys with values in an indexed array?
(12 answers)
Closed 4 months ago.
I have following arrays:
$keys
array (size=2)
0 => string 'foo' (length=3)
1 => string 'buz' (length=3)
$data
array (size=3)
'foo' => int 1
'bar' => int 2
'buz' => int 3
How to get $data array filtered by $keys values ? Desired output:
array (size=3)
'foo' => int 1
'buz' => int 3
array_intersect_key should be able to help you out here
array_intersect_key($data, array_flip($keys));
The array_flip is needed because array_intersect_key operates on keys, so this makes sure both arrays are in the right format.
