在PHP中动态访问对象属性数组元素

Question

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'];

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

I have tried:

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

but it returns

Fatal error: Cannot use string offset as an array

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

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

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

Answer 1

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

$i = 1;
$j = 1;

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