在 PHP 中动态访问对象属性数组元素 [英] Dynamically access an object property array element in PHP

问题描述

我有一个对象，我想与它动态交互.我想将 game1_team1 重命名为:

I have an object, that I would like to interact with dynamically. I would like to rename the game1_team1 in:

$default_value = $individual_match->field_match_game1_team1[0]['value'];

成为 game1_team2、game2_team1、game2_team2、game3_team1 等.基于他们所处的循环.

to be game1_team2, game2_team1, game2_team2, game3_team1, etc. Based on the loop they are in.

我试过了:

$dynamic = 'field_match_game'.$i.'_team'.$j;
$default_value = $individual_match->$dynamic[0]['value'];

但它返回

致命错误:不能使用字符串偏移作为数组

Fatal error: Cannot use string offset as an array

更新:根据 Saul 的回答，我将代码修改为:

Update: Based on Saul's answer, I modified the code to:

$default_value = $individual_match->{'field_match_game'.$i.'_team'.$j}[0]['value'];

消除了致命错误，但没有返回值.

which got rid of the Fatal error, but doesn't return a value.

推荐答案

$individual_match->field_match_game1team1[0]['value'] = 'hello1';

$i = 1;
$j = 1;

$default_value = $individual_match->{'field_match_game'.$i.'team'.$j}[0]['value'];
