Question

我有一个班级队员{}。我有一系列字符串$ teams = array（＆＃39; team1＆＃39;，＆＃39; team2＆＃39;，＆＃39; team3＆＃39;）。我想遍历数组并创建一个对象，每个字符串作为对象名称。

class Team{}

$teams = array('team1', 'team2', 'team3');

foreach ($teams as $team) {
    $team = new Team();
}

所以$ team1，$ team2和$ team3成为对象。

感谢您的帮助。

Answer 1

假设团队有一个属性"name"，就这样做：

class Team {

  private $yourPropertyForName;

  public function __construct($name) {
    $this->yourPropertyForName = $name;
    //initialise the rest of your properties
  }
}

$teamList = [];    
$teams = array('team1', 'team2', 'team3');

foreach ($teams as $teamName) {
   array_push($teamList, new Team($teamName));
}
//teamList now contains the three Team objects

Answer 2

You can use this just another "$" symbol for the team variable would give what you are expecting.

<?php
    Class Team{}    
    $teams = array('team1', 'team2', 'team3');    
    foreach ($teams as $team) {
       $$team = new Team();
    }
    var_dump($team1);
    var_dump($team2);
    var_dump($team3);    
?>

哪个输出像 object（Team）＃1（0）{} object（Team）＃2（0）{} object（Team）＃3（0）{}

正如您所料：）
