using variable to reference array value

[denoteone]

I think my issue is referencing my array value with a php variable

 

function getPrice($pulse_id) { 

$sub_array = $pulse_data['$pulse_id'];
$info = explode("	", $sub_array);
$pulse_price = $info[5];
return $pulse_price;

}

echo getPrice('231');

[XGCommander]

$sub_array = $pulse_data['$pulse_id'];

 

change it to

 

$sub_array = $pulse_data[$pulse_id];

 

only use single quotes when you are inserting a value directly.
