how to echo print_r() array output

Question

I got a bit probs how to echo print_r() output array.

Array ( 
    [[email protected]] => Array ( 
        [0] => 70,80 
        [1] => 90,100 
    ) 
    [[email protected]] => Array ( 
        [0] => 10 
    ) 
)

function array_combines($arr1,$arr2) { 
   $out = array(); 
   foreach($arr1 as $key1 => $value1)    { 
    $out[$value1][] = $arr2[$key1]; 
   } 
   return $out;
} 
print_r(array_combines($a,$b));

I expecting echo:

key: [email protected]
value: 70,80 90,100

key: [email protected]
value: 10

$a = ['[email protected]', '[email protected]', '[email protected]']; $b = ['70,80', '10', '90,100']; — marina

Loop the array like shown below. The key is the email, then use implode() on the value

foreach ($array as $key => $value) {
    echo "key: " , $key , PHP_EOL;
    echo "value: " , implode(' ',$value) , PHP_EOL , PHP_EOL;
}

Output:-

key: [email protected]
value: 70,80 90,100

key: [email protected]
value: 10

First format your array to expected pattern using array_walk() and finally print using implode() the array by </br> or PHP_EOL glue. Example:

array_walk($arr, function (&$item, $key) { $item = "key: {$key}</br>value: " . implode(" ", $item); });

echo implode('</br></br>', $arr);
