remove spaces in a array php - php

Question

for this array,
Array (
[0] => 'HOST:'
[1] => 'killbill'
[2] =>
[3] =>
[4] =>
[5] =>
[6] =>
[7] =>
[8] =>
[9] =>
[10] =>
[11] => 'Loss%'
[12] =>
[13] =>
[14] => 'Snt'
[15] =>
[16] =>
[17] => 'Last'
[18] =>
[19] =>
[20] =>'id'
)
it has empty values.by using this code it gives
foreach($array as $key => $subarray) {
$array[$key] = preg_grep('/^$/', $subarray, PREG_GREP_INVERT);
}
array (
[0] => HOST:
[1] => killbill
[11] => Loss%
[14] => Snt
[17] => Last
[20] =>id
)
that means it removes all the spaces. but it has the original key values .(compair above one and bellow one. then can get a clear idea what i'm saying).but i want to have it like this.
array (
[0] => 'HOST:'
[1] => 'killbill'
[2] => 'Loss%'
[3] => 'Snt'
[4] => 'Last'
[5] => 'id'
)
key values as 1,2,3,4.... so how could i get that.

Answer 1

simply use this instead of Foreach
array_values(array_filter($array));
that will remove the space and reorder your array.

Answer 2

Just use array_filter().
$array = array_filter($array);
That will remove all the empty values -- ie blank, null, false, zero.
If you only want to remove values that are empty strings and keep other empty values (eg zero), you can specify the second parameter for array_filter(), which allows you to define a function to specify which elements should be filtered.
$array = array_filter($array, function($val) {return $val!=='';});
Hope that helps.

Answer 3

try this function it will help you to sort out the issue
$arr = array_map('array_values', $arr);

Answer 4

Use array_diff function
<?php
$array_space = array(0,3,4,45,12,"",54,23);
$remove = array("");
print_r(array_diff($array_space,$remove));
?>
See Output here

Answer 5

at start you need to take the array i gave him a name $arrWords
$arrWords = array_filter($arrWords, 'trim');
after i clean all the empty spaces i will make new array keys
$arrWords = array_values($arrWords);
