Question

I’m creating an array from a string with comma separated values

$result = "apple, hello word, 80, apple";    

$result = str_getcsv($result); //create array     
$result = array_filter(array_map('trim', $result)); //remove whitespaces

Some characters in a value have spaces between them, like hello world and I want to replace the spaces with a dash (to make the the string URL friendly.) Example: hello-world

I thought of iterating through the array using str_replace but can it be done better using array_map like I’m doing to trim?

Answer 1

str_replace can work directly on arrays as well:

$result = str_replace(' ', '-', $result);

This will have the same result as the less readable

$result = array_map(function($el) { return str_replace(' ','-',$el); }, $result);

Both are also equivalent to the classic

foreach($result as &$element) {
    $element = str_replace(' ', '-', $element);
}
