一旦currentDate> = $ publishDate，显示php文件的特定部分

Question

可以说我有一个文件foo_version1.php及其实时发布的。 我需要在将来的某个特定日期和时间为其添加新内容。 一旦发布日期等于今天的日期，是否有办法使新内容显示？

到目前为止，这是我所做的...

<?php
    //set the time zone to LA
     date_default_timezone_set('America/Los_Angeles');

    class Timelock{
      var $fileName;
      var $contentName;
      var $publishDate;

      function __construct($fileName, $contentName, $publishDate){
        $this->contentName = $contentName;
        $this->publishDate = $publishDate;
        $this->fileName = $fileName;
      }
      function contentName(){
        return $this->contentName;
      }
      function publishDate(){
        return $this->publishDate;
      }
      function fileName(){
        return $this->fileName;
      }

    }

   //create objects that has certain publish date
   $chargers = new Timelock("content1.php" ,"San Diego Chargers", "2013-10-18 16:41:00");
   $colts = new Timelock("content2.php" ,"Indianapolis Colts", "2013-10-18 16:41:03");
   $vikings = new Timelock("content3.php" ,"Minnesota Vikings", "2013-10-18 16:41:06");
   $eagles = new Timelock("content4.php" ,"Philadelphia Eagles", "2013-10-18 16:41:09");
   $cowboys = new Timelock("content5.php" ,"Dallas Cowboyws", "2013-10-18 16:41:12");


   //add the contents with timelocks into the array
   $contentArray = array();
   $contentArray[] = $chargers;
   $contentArray[] = $colts;
   $contentArray[] = $vikings;
   $contentArray[] = $eagles;
   $contentArray[] = $cowboys;


    //include the file if the publish date is today
    foreach($contentArray as $obj){
        if( strtotime($currentDate) >= strtotime($obj->publishDate())){
            include ($obj->fileName());
        }
    } 
?> 

问题是每次我需要添加不理想的新内容时，我都需要创建新的php文件。 那么回到问题上，还有另一个可以优雅地做到这一点吗？

Answer 1

您可以将所有内容文件放入单个“ content.php”文件中。 接下来，我不会将文件传递到对象中，因为我们现在可以假定所有内容都在content.php中。

现在，我要做的是在包含过程中使用URL中的参数将名称或日期传递到content.php文件。

在您的content.php中，我将使用带有传递参数的switch语句，并回显正确的内容。

代码如下：

index.php：

<?php
//set the time zone to LA
 date_default_timezone_set('America/Los_Angeles');

class Timelock{
  private $contentName;
  private $publishDate;

  public function __construct($contentName, $publishDate){
    $this->contentName = $contentName;
    $this->publishDate = $publishDate;
  }
  public function contentName(){
    return $this->contentName;
  }
  public function publishDate(){
    return $this->publishDate;
  }
  public function fileName(){
    return "content.php" . "?name=" . $this->contentName;
  }

}

//create objects that has certain publish date
$chargers = new Timelock("San Diego Chargers", "2013-10-18 16:41:00");
$colts = new Timelock("Indianapolis Colts", "2013-10-18 16:41:03");
$vikings = new Timelock("Minnesota Vikings", "2013-10-18 16:41:06");
$eagles = new Timelock("Philadelphia Eagles", "2013-10-18 16:41:09");
$cowboys = new Timelock("Dallas Cowboyws", "2013-10-18 16:41:12");


//add the contents with timelocks into the array
$contentArray = array();
$contentArray[] = $chargers;
$contentArray[] = $colts;
$contentArray[] = $vikings;
$contentArray[] = $eagles;
$contentArray[] = $cowboys;


//include the file if the publish date is today
foreach($contentArray as $obj){
    if( strtotime($currentDate) >= strtotime($obj->publishDate())){
        include ($obj->fileName());
    }
} 
?> 

content.php：

 <?php
switch($_GET["name"]) {
   case "San Diego Chargers":
       echo "We are in San Diego Chargers content.";
       break;
   default:
       echo "No content found for " . $_GET["name"] . ".";
}
?>

更加高效：根据每个“ contentX.php”所包含的内容，您可以创建一个MySQL数据库，该数据库将存储团队名称，日期和内容。 然后您的页面可以检查日期，并从数据库中获取内容以发布到页面。
