PHP - 类内的全局变量 - 在内部函数中访问

标签: php arrays laravel global-variables

我正在为学校做一个项目,我第一次使用laravel框架。我有一个小问题,我已经被困了好几天,尝试了很多不同的方法 - 没有用。

我已经构建了一个时间函数,它将接受多个参数然后通过while循环检查db然后将所有结果添加到'global'数组中,然后另一个函数将测试该全局数组并检查其中的值。

我遇到的问题是我无法正确访问全局数组的函数:

我在网上尝试了很多不同的想法但是可以获得类的内部函数来访问全局数组 -

有谁知道如何做到这一点的简单方法?感谢

尝试(在最高级 - 课前,以及顶级课程内)

$Global['ScheduleTest'] = array();

global $ScheduleCheck = array();

(inside class ) private $ScheduleCheck = array();

完整代码:::::::

<?php

global $ScheduleCheck = array() ;

class CourseRegistrationController extends BaseController {

public function __construct() {
    $this->beforeFilter('csrf', array('on'=>'post'));
}

.....

// Function to test time overlaps

function testTimeOverlap($course ,$regday, $start_time,$end_time)
    {
        $start_time1 = (substr($start_time, 0, 5)) ;
        $end_time1 = (substr($end_time, 0, 5)) ;

        $ScheduleArr = makeSchedule();

        $reg_days = explode(",",$regday);

        foreach ($reg_days as $rday)
        {
            foreach ($ScheduleArr as $schedule)
            {

                if((strtolower($rday))==(strtolower($schedule['day'])))
                {

                    $start_time2 = (substr($schedule['stime'], 0, 5)) ;
                    $end_time2 = (substr($schedule['etime'], 0, 5)) ;

                    if(testTime($start_time1,$end_time1,$start_time2,$end_time2))
                    {
                        array_push($ScheduleCheck, array("course"=>$course,"value"=>"true","day"=>$rday ));
                    }
                  else
                  {
                    array_push($ScheduleCheck, array("course"=>$course,"value"=>"false","day"=>$rday ));
                  }

                }
                else
                {
                    array_push($ScheduleCheck, array("course"=>$course,"value"=>"true","day"=>$rday ));
                }

            }

        }
    }


// Another function to go through the global array

function finalTimeTest()
    {
        testNewTime((strtolower(Input::get('course_id'))),(strtolower(Input::get('lecture_id'))),(strtolower(Input::get('tutorial_id'))),(strtolower(Input::get('lab_id'))));

        foreach($ScheduleCheck as $ckTime)
        {
            if($ckTime['value']=="true")
            {
                return true;
            }
            else
            {
                return ($ckTime['course']." ");
            }
        }
    }

?>

这些&#34;功能&#34;应该被定义为类的方法。

class ScheduleChecker {

    protected $scheduleCheck = array();

    // Your functions should be placed in here!

    public function getScheduleCheck()
    {
        return $this->scheduleCheck;
    }

}

然后您可以从方法中引用该属性。

public function finalTimeTest()
{
    // Using $this to call the testNewTime method.
    $this->testNewTime((strtolower(Input::get('course_id'))),(strtolower(Input::get('lecture_id'))),(strtolower(Input::get('tutorial_id'))),(strtolower(Input::get('lab_id'))));

    // Using $this to get the scheduleCheck property.
    foreach($this->scheduleCheck as $ckTime)
    {
        if($ckTime['value']=="true")
        {
            return true;
        }
        else
        {
            return ($ckTime['course']." ");
        }
    }
}

您可能希望将此绑定到Laravel的容器(app/start/global.php中):

App::instance('schedule', new ScheduleChecker);

然后,在您的控制器中,获取$scheduleCheck属性:

$scheduleCheck = App::make('schedule')->getScheduleCheck();
