How to get the minimum value from array row

Question

I trying to get the minimum values from the any column contains \"xx\" in the column name.

Below is my code:

Answer 1

1. Iterate each row/subarray with a foreach() loop or array_walk().
2. Extract and display the id (first element) value with array_shift().
3. Call min() on the remaining values in the respective subarray to determine the lowest value.

No conditional expressions. No unnecessary variables. Clean, concise, and effective.

Code: (Demo)

$array = [
    ['id' => 1, '10xx' => 14, '11xx' => 32, '12xx' => 4],
    ['id' => 2, '10xx' => 13, '11xx' => 36, '12xx' => 41]
];

array_walk($array, function($row) {
    echo array_shift($row) , " : " , min($row) , "\n";
});

Output:

1 : 4
2 : 13
