Dynamically access an object property array element in PHP
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开发者_Go百科 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.
$individual_match->field_match_game1team1[0]['value'] = 'hello1';
$i = 1;
$j = 1;
$default_value = $individual_match->{'field_match_game'.$i.'team'.$j}[0]['value'];
'Renaming' is not possible unless you create a new property, and delete the old one. Access dynamic names like this:
$dynamic = "field_match_$i_team$j";
$default_value = $individual_match->$dynamic[0]['value'];
Note the $
between ->
and dynamic
.
Delete and create example:
$oldProperty = "field_match_1_team1";
$newProperty = "field_match_$i_team$j";
$hold = $individual_match->$oldProperty;
unset($individual_match->$oldProperty);
$individual_match->$newProperty = $hold;
Look at this : http://php.net/manual/en/function.get-class-vars.php You can list all object's properties in array and select only needed.
