$newArray = array_combine(
range(2,count($originalArray)*2,2),
array_values($originalArray)
);
#2
0
The array_values() function returns an array containing all the values of an array and also it reset all the keys. you can do it as
array_values()函数返回一个包含数组所有值的数组,并重置所有键。你可以这样做
$arr = array(0 => 1, 1 => 3, 2 => 5, 3 => 13, 4 => 32, 5 => 51);
$count = 1;
$tempArr = array();
foreach ($arr as $key => $val) {
$tempArr[$count * 2] = $val;
$count++;
}
var_dump($tempArr);exit;
Try this code at your side.
