Question

I need to do a PHP while loop, but only if a variable is true. And I can’t really put the while loop in an “if” statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this?

Here’s the basic idea:

if(condition){
  while(another_condition){
    //huge block of code loops many times
  }
} else {
  // huge block of code runs once
}

I want the huge block of code to execute regardless of the state of the condition variable– but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true.

The following code doesn’t work, but gives an idea of what I want to accomplish:

if(condition){ while(another_condition){ }
  // huge block of code
if (condition){ } } // closes the while loop-- obviously throws an error though!

thanks in advance.

Answer 1

Is this kind of what you are looking for?

while (condition && another_condition) {
   // large block of code
}
if (!condition) {
   // do something else
}
