如何从逗号分隔的数字列表中删除某个数字

Question

I have this comma delimited list 0,0,0,0,5,0,7,8,9,10 and i would like to get rid of the number zero represented as a number on its own right and not the zero in 10.

The list is represented in the variable $str and this is the code i am trying to remove the zero with.

$str;

$myArray = explode(',', $str);

if (($key = array_search('0', $myArray)) !== false) {
    unset($myArray[$key]);
}
print_r($myArray);
$csv = implode(', ', $myArray);
echo $csv;

but this gives 0, 0, 0, 5, 0, 7, 8, 9, 10

This code does not do the job as i would have liked.What can i do to get rid of the zeros?.

Answer 1

array_filter comes to the rescue:

$myArray = explode(',', '0,0,0,0,5,0,7,8,9,10');
print_r(array_filter($myArray, function($el) { return $el; }));
// ⇒ 
/*
Array
(
    [4] => 5
    [6] => 7
    [7] => 8
    [8] => 9
    [9] => 10
)
