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){

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

    $data[$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){

    $assign = "50";

    $data[$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")
