I have something like a vocabulary list with every vocabulary containing a number and the word. I have the same list of vocabulary but unsorted and in another language, the numbers match the meaning. So the same word has in both languages the same number. How can I match both vocabularys together and being in the same order of the main language? Example:
Input:
English Array (sorted) German Array (unsorted)
74 Apple 6 Auto
6 car 564 Zug
564 train 74 Apfel
Output: the German Array is sorted in the same way as the English Array
74 Apple 74 Apfel
6 car 6 Auto
564 train 564 Zug
Help is much appreciated. Thank you :)
Inputs:
$english=["74 Apple","6 car","564 train"];
$german=["6 Auto","564 Zug","74 Apfel"];
First, create an array with keys in the desired order:
array_map(function($v)use(&$sorting_keys){return $sorting_keys[substr($v,0,strpos($v,' '))]='';},$english);
//var_export($sorting_keys);
// array (
// 74 => '',
// 6 => '',
// 564 => '',
// )
Next, reassign keys to the german array elements based on the leading id number
array_map(function($v)use(&$keyed_german){return $keyed_german[substr($v,0,strpos($v,' '))]=$v;},$german);
//var_export($keyed_german);
// array (
// 6 => '6 Auto',
// 564 => '564 Zug',
// 74 => '74 Apfel',
// )
Finally, transfer the values from $keyed_german to $sorting_keys (and reset the keys if you wish with array_values()):
$sorted_german=array_values(array_replace($sorting_keys,$keyed_german));
var_export($sorted_german);
Output:
array (
0 => '74 Apfel',
1 => '6 Auto',
2 => '564 Zug',
)
