PHP Getting First Element Of Associative Array [duplicate]

Question

I have this array :

$fr_coin_multiplier_asc = array('BTC'=>30, 
                                'ETH'=>28, 
                                'BNB'=>36, 
                                'USDT'=>39,
                                'NEO'=>8, 
                                'LTC'=>9, 
                                'BCC'=>17);
asort($fr_coin_multiplier_asc);

and I want to get the first element of that array after sorted using this method :

reset($fr_coin_multiplier_asc);
print_r(current($fr_coin_multiplier_asc));

in this case, i'm expecting NEO and 8 as result, but it only gives me 8. how to get NEO and also 8?

thank you

Use key($array)

Try using key($fr_coin_multiplier_asc). Per the PHP documentation:

key() returns the index element of the current array position.

Modern answer (PHP >= 7.3):

array[ array_key_first( $array ) ]

See https://www.php.net/manual/en/function.array-key-first.php

Try this construction

key($fr_coin_multiplier_asc) . ' => ' . current($fr_coin_multiplier_asc);

It return key and value from array. Hope it's help for you

Here we try to display the array content after the sorting, but we break after we get the first one !

$fr_coin_multiplier_asc = array('BTC'=>30, 
                                'ETH'=>28, 
                                'BNB'=>36, 
                                'USDT'=>39,
                                'NEO'=>8, 
                                'LTC'=>9, 
                                'BCC'=>17);
asort($fr_coin_multiplier_asc);
reset($fr_coin_multiplier_asc);
print_r(current($fr_coin_multiplier_asc));
echo "<br>";
foreach($fr_coin_multiplier_asc as $x => $x_value) {
    echo $x.":".$x_value;
    break;  
}

In this case the output will be : NEO:8

With PHP 5.4+ (but might cause an index error if empty so I use the fallback ??):

\array_values($array)[0] ?? null;
