PHP - 变量之外的数组名称

Question

Is it possible to use php variable as a part of an array name. like this my arrays are Fday1, Fday2....but i cant go with the foreach keys beacause there are different counts of values for each array

$FdayArray = "Fday".$FdayKey;
array_push($FdayArray, $forecast);

the FdayKey would be a number between 1-9 How do I do this correctly?

Answer 1

You are looking for the variable variables feature of php.

Sometimes it is convenient to be able to have variable variable names. That is, a variable name which can be set and used dynamically. It takes the value of a variable and treats that as the name of a variable

You would use

array_push($$FdayArray, $forecast);
