PHP Array：按字符串的一部分分组

Question

I have an array containing the strings below

'Proxima Nova Bold'
'Proxima Nova Italic'
'Proxima Nova Regular'
'Skolar Bold'
'Skolar Italic'
'Skolar Regular'
'Consolas'

i'd like to have an output like

'Proxima' 
'Skolar' 
'Consolas'

essentially grouping by the parent/master name...is it possible in PHP?

Answer 1

Explode each string into words, return the first word, and then use array_unique to remove the duplicates.

array_unique(array_map(function($str) {
    $words = explode(' ', $str);
    return $words[0];
}, $array));

Answer 2

This should be the easiest way to do it:

//Create an empty array
$new_array = array();
foreach($array as $value) {
  //Explode the text into a new array, separated by space
  $first_part = explode(" ", $value);
  //Push the first word into the new array
  array_push($new_array, $first_part[0]);
}
//Now get only unique values
print_r(array_unique($new_array));
