在PHP函数之间传递变量

Question

I have the following function:

class TariffFareController {

public static function checkRunin($fieldPickup) {

    $runInThreshold = 5;
    $fieldDestination = 6;

    if ($fieldPickup > $runInThreshold && $fieldDestination > $runInThreshold)

    {

        if ($fieldPickup > $fieldDestination)

        {

            $distance = $fieldPickup - $runInThreshold;

        } else {

            $distance = $fieldDestination - $runInThreshold;

        }


       }
}

I want to pass $distance to this function:-

private static function getFare($int_terminate) {

    //CODE
    //eg// if($distance > 5) {

        //do something

    }

}

How can I do this?

Answer 1

When you say its does not work ... it basically because $diffrent was not properly declared so you are having scope issues

My Assumption

• Both checkRunin and getFare are method of the same class TariffFareController
• $int_terminate is different from $distance

From your class

• $distance not declared as static
• getFare is trying to access $distance that has not been declared

Simple Solution

class TariffFareController {
    private static $distance = 0;

    public static function checkRunin($fieldPickup) {
        $runInThreshold = 5;
        $fieldDestination = 6;
        if ($fieldPickup > $runInThreshold && $fieldDestination > $runInThreshold) {
            if ($fieldPickup > $fieldDestination) {
                self::$distance = $fieldPickup - $runInThreshold;
            } else {
                self::$distance = $fieldDestination - $runInThreshold;
            }
        }
        printf("self:\$distance = %d ; // Called %s :
", self::$distance, __METHOD__);
    }

    public static function getFare($int_terminate) {
        printf("self:\$distance = %d ; // Called %s :
", self::$distance, __METHOD__);
    }
}

TariffFareController::checkRunin(10);
TariffFareController::getFare(2);

Output

self:$distance = 5 ; // Called TariffFareController::checkRunin :
self:$distance = 5 ; // Called TariffFareController::getFare :
