两个数组如何在单个foreach循环中扩展？

Question

I want to extend two array in single foreach loop like ..

$array=array(1,2,3,4,5,6,7,);
$array2=array(1=>'b','2=>c',3=>'d',4=>'e',5=>'f',6=>'g',7=>'x');

foreach($array as first && $aaray2 as second){
  echo first;
  echo second;    
}

Is it possible? how I call indexes of each array and values of each array

Answer 1

Since your arrays don't use named keys you can reuse the array key. If you use named keys this only works if the keys are the same.

foreach ($array as $key => $value) {
    echo $value;
    echo $array2[$key];
}

You could also use a for loop counting from 0 to the array length since php automatically uses numbers as keys if you don't specify any, but the above solution is probably more readable and will work with named keys.
