I am adding key-value pairs to my array like so:
JavaScript
x
$array[] =
[
"key1" => "value1",
"key2" => "value2",
// ...
]
And I want to add another key foo
, only if the variable $bar
is set:
JavaScript
$array[] =
[
"key1" => "value1",
"key2" => "value2",
"foo" => $bar
// ...
]
How to add the "foo" => $foo
pair only if $foo
is set?
What I do right now is to add empty (""
) value to the key "foo"
if $bar
is not set, but I want to not add it at all

Answer
Every time I need to fill array based on some condition, I do something like this:
JavaScript
$array = [];
$array['key1'] = 'value1';
$array['key2'] = 'value2';
if (isset($bar)) {
$array['foo'] = $bar;
}
