Remove all values => 0 from array and reverse it - php

Question

I am a PHP beginner and have the following problem that I completely get stuck. I have an array in this format
Array (
[date] => 0
[author] => 1
[categories] => 1
[tags] => 0
[comments] => 0
[readmore] => 0
)
Now I need to remove all items that are [value] => 0 from that array and get it in this format
Array (
[0] => author
[1] => categories
)
Any input in this is much appreciated.

Answer 1

use array_filter and then array_keys:
$array = array ( 'date' => 0, 'author' => 1, 'categories' => 1, 'tags' => 0, 'comments' => 0, 'readmore' => 0 );
$array = array_filter($array);
print_r(array_keys($array));
output
Array
(
[0] => author
[1] => categories
)

Answer 2

There is a function called array_search() out there. Assuming the only possible values are 0 and 1, you can just serach the whole array for this value:
$array = [
'date' => 0,
'author' => 1,
'categories' => 1,
'tags' => 0,
'comments' => 0,
'readmore' => 0
];
$new_array = array_flip(array_search(1, $array));
So print_r($new_array) will give you your desired result.

Answer 3

You can try something like this:
foreach($array as $item){
if($item == "0"){
unset($item);
}
}
Or some modification with using unset function.

Answer 4

This is also do the job...
$dataSource = array('data' => 0,
'author' => 1,
'categories' => 1,
'tags' => 0,
'comments' => 0,
'readmore' => 0,
);
$updatedDataList = array();
foreach ($dataSource as $key => $value) {
if($value !== 0) {
$updatedDataList[] = $key;
}
}
print_r($updatedDataList);

#savethegold you can save your gold like below :D
<?php
$Array1 = array("date" => 0, "author" => 1, "categories" => 1, "tags" => 0, "comments" => 0, "readmore" => 0 );
foreach ($Array1 as $key => $value) {
if($value == 0){
unset($Array1[$key]);
}
}
$finalArr = array_keys($Array1);
print_r($finalArr);

Answer 6

You can try following code
$yourArray = Array ("date" => 0,"author" => 1, "categories" => 1,"tags" => 0, "comments" => 0,"readmore" => 0 );
$removeZeroFromArray = array(0);
$desiredResult = array_diff($yourArray, $removeZeroFromArray);
echo"<pre>";
print_r(array_keys($desiredResult));
echo"</pre>";
Your output will be like
Array
(
[0] => author
[1] => categories
)
Alternate way should be
$desiredResult = array_filter($yourArray, function($a) { return ($a !== 0); });
Hope it helps!

<?php
$array = array ( 'date' => 0, 'author' => 1, 'categories' => 1, 'tags' => 0, 'comments' => 0, 'readmore' => 0 );
$resutl = [];
foreach($array as $k => $v)
{
if($v != 0)
$result[] = $k;
}
print_r($result);
