Effective way to get array index and value names

Question

I have a 0 indexed array that I can't do much about, but inside this array there are values that I need to echo. example array is:

$x =  array(0 => array('store'=> 107));

I would like to have 2 variables that both echo texts store and 107

I could do this, using

$var1 = array_keys($x[0]); 
$var2 = array_values($x[0]); 

echo $var1[0]; // store 
echo $var2[0]; // 107

I would like to know if there is a more effective way of getting those values, or remving that first 0 index. as array_filter($x) or unset($x) obviously don't work as in other cases.

$x = $x[0] will give $x = array('store'=> 107) and you may keep it like that — Kevin Kopf

You could use current($x) instead of $x[0]. I don't see the benefit, though. — Barmar

thanks @Barmar I didn't know current could be used for this. Although there Nordenheim's answer is neat also. I suppose you don't think there is any different to from memory footprint side, even though it is too small to scale. I just got curious to know. — soni-b3196413

As an alternative, you could also use combinations of key() and reset() if you're curious.

$x =  array(0 => array('store'=> 107));

$y = reset($x); // point to first element
$key = key($y); // get the current key, store
$val = reset($y); // get the value
echo $key; // store
echo $val; // 107

this should work for you.

$x =  array(0 => array('store'=> 107));

foreach($x as $y){
    foreach ($y as $key => $value){
        echo $key;
        echo $value;
    }
}
