Multidimensional array element if empty delete entire sub-array PHP - php

Question

I'm trying to delete sub array of my multidimensional array, if any of the value is empty, than delete entire sub array. I want a universal function for the same! Dont want to type specific keys. And than ReIndex the newly formed array.
My array is like
Array
(
[0] => Array
(
[name] => Test
[mobile] => 613594551
[email] => test#test.com
)
[1] => Array
(
[name] => Test1
[mobile] => 613594552
[email] => test2#test.com
)
[2] => Array
(
[name] => Test2
[mobile] => 613594553
[email] => test3#test.com
)
[3] => Array
(
[name] => Test3
[mobile] => 613594554
[email] => test4#test.com
)
)
So if my array is
Array
(
[0] => Array
(
[name] =>
[mobile] => 613594551
[email] => test#test.com
)
[1] => Array
(
[name] => Test1
[mobile] =>
[email] => test2#test.com
)
[2] => Array
(
[name] => Test2
[mobile] => 613594553
[email] =>
)
[3] => Array
(
[name] => Test3
[mobile] => 613594554
[email] => test4#test.com
)
)
Than display
Array
(
[0] => Array
(
[name] => Test3
[mobile] => 613594554
[email] => test4#test.com
)
)

Answer 1

Elaborating on Martin's answer, you can use array_filter() for both the source array and the nested array:
$filtered_array = array_filter($array, function($item){
return count($item) == count(array_filter($item));
});
sort($filtered_array); // to reindex

Answer 2

Use array_filter() to iterate all records for each person and remove those that have an empty value. Number of records before and after array_filter() has to be equal if all records are filled. If they're not remove the person using unset().
Note, that this function works in-place, so it modifies the original array.
<?php
$array = [
[
'name' => 'Test1',
'mobile' => 123456789,
'email' => null
], [
'name' => 'Test2',
'mobile' => 123456789,
'email' => 'test2#test.com'
], [
'name' => null,
'mobile' => 123456789,
'email' => 'test3#test.com'
],
];
function removeEmpty(&$arr) {
foreach ($arr as $index => $person) {
if (count($person) != count(array_filter($person, function($value) { return !!$value; }))) {
unset($arr[$index]);
}
}
}
removeEmpty($array);
print_r($array);
Prints:
Array
(
[1] => Array
(
[name] => Test2
[mobile] => 123456789
[email] => test2#test.com
)
)

Answer 3

Assuming that an array item might have different keys:
$array = array(
0=>array('name'=>'','test'=>2),
1=>array('name'=>'sadad','test'=>2),
);
foreach($array as $index=>$item) {
$keys = array_keys($item); //here is the assumption
//you can define it before the foreach
//by checking the first array if YOU are 100% sure
//all items in the array have the same keys: name, mobile, email
foreach($keys as $key) {
if(empty($item[$key])) {
unset($array[$index]);
break;
}
}
}
var_dump($array);
Output:
array(1) {
[1]=>
array(2) {
["name"]=>
string(5) "sadad"
["test"]=>
int(2)
}
}
