PHP：Function - 返回2个变量（Boolean + $ variable）

Question

Issue Resolved : Here is the solution :

function testCoreq()
    {
        $coreqTest = makeCoreq();

        if(empty($coreqTest))
        {
            return array(true);
            break;
        }
        else
        {
            foreach ($coreqTest as $ctest)
            {
                if($ctest['value'] == "true")
                {
                    return array(true);
                    break;
                }
                else
                {
                    return array(false,$ctest['coreqID']);
                }
            }
        }

    }

if(testCoreq()[0])
{
  //do something
}
else
{
  return testCoreq()[1]
}   

I'm doing a school project and hit kind of a bump.

I created a function and i want it to either return "true" (boolean) or "false" (boolean) + a variable.

I searched the net quite a bit but wan't able to find a simple way to do this .

Is there any way to this this ? //Thanks

The function is working properly but when it is returning the variable - it is also assuming that the function is returning "true" when i want it to return false + the value like :

else
                {
                    return $ctest['coreqID'];
                    return false;
                }

Here is the code :

function testCoreq()
    {
        $coreqTest = makeCoreq();

        if(empty($coreqTest))
        {
            return true;
            break;
        }
        else
        {
            foreach ($coreqTest as $ctest)
            {
                if($ctest['value'] == "true")
                {
                    return true;
                    break;
                }
                else
                {
                    return $ctest['coreqID'];
                }
            }
        }

    }

I am using it like this:

if (testCoreq())
{
 // do something
}
else
{
 // return the variable
}

but even if the first statement is false , then it is returning the variable - it is assuming the function is true.

Answer 1

You can try to return -1 on true and other for false to decrease amount of returning values. Next option is to return array of values. The other option would be to pass reference variable in the function.
