如何在foreach循环中制作数组 - php？

Question

arrayOne + foreach loop = arrayTwo

<?php /* version +7 */

$input = array("teamA","teamB","teamC");

foreach($input as &$value){

    $assign = "50"; /* The data just temp */

    $data = array($value=>$assign);

}

echo $data["teamA"];

?>

Answer 1

我想你正在寻找这个：$input = array("teamA","teamB","teamC");$data = [];foreach($input as $value){&nbsp; &nbsp; $assign = "50"; /* The data just temp */&nbsp; &nbsp; $data[$value] = $assign;}echo $data["teamA"];如果对于所有键都相同：$assign$data = array_fill_keys($input, 50);

Answer 2

<?php$input = array("teamA","teamB","teamC");$data = array();foreach($input as $value){&nbsp; &nbsp; $assign = "50";&nbsp; &nbsp; $data[$value] = $assign;}echo $data["teamA"];?>将新的键值对分配给数组，可以通过以下方式访问：，其中键由初始给定数组的值组成$data[$value] = $assign;$input = array("teamA","teamB","teamC")
