如何在 foreach 循环中创建数组 - php？

Question

arrayOne + foreach 循环 = 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 $data["teamA"];如果所有键$assign都相同：$data = array_fill_keys($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： $data[$value] = $assign;，其中键由最初给定数组的值组成$input = array("teamA","teamB","teamC")
