显示 php 文件的某些部分，一旦当前日期 >= $publishDate - show certain part of a php file once currentDate >= $publishDate

假设我有一个文件foo_version1.php，它已经上线并发布。我需要在将来的某个特定日期和时间向其添加新内容。有没有办法在发布日期等于今天的日期后显示新内容？

这是我到目前为止所做的...

<?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());
        }
    } 
?>

这样做的问题是，每次我需要添加新内容时，我都需要创建新的 php 文件，这并不理想。所以回到问题还有别的可以优雅地做到这一点吗？

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设所有内容都在内容.php中。

现在我要做的是在包含期间将名称或日期传递给内容.php文件，并在 URL 中带有参数。

在您的内容.php中，我会使用带有传递参数的 switch 语句并回显出正确的内容。

代码如下：

索引.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());
    }
} 
?>

内容.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"] . ".";
}
?>

为了提高效率：根据每个"contentX.php"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，并从数据库中获取要发布到页面的内容。

希望我能帮忙，卢克
