我开始一点一点地学习如何用 PHP 编程。但是我遇到了一个我自己无法解决的问题。所以我需要一点帮助。问题是，在我的函数中，我从数据库中获取信息。我想在下面发布的其他函数中使用变量 $DisplayProducts01Title

获取数据的函数：

//GetAllPages
function GetAllPages() {
    $GetAllPagesSql = "SELECT ContentPages.ContentPagesID, ContentType.ContentTypeName, ContentInformation.ContentInformationTitle, ContentPages.ContentPagesOrder FROM `ContentPages` INNER JOIN ContentType ON ContentPages.ContentTypeID = ContentType.ContentTypeID INNER JOIN ContentInformation ON ContentPages.ContentInformationID = ContentInformation.ContentInformationID ORDER BY ContentPagesOrder";
    $GetAllPagesQuery = mysql_query($GetAllPagesSql);
    while (($GetAllPagesRow = \mysql_fetch_assoc($GetAllPagesQuery)) != false) {
        if($GetAllPagesRow[ContentTypeName] == 'products01') {
            DisplayProducts01DesignFunction();
            $DisplayProducts01Title = $GetAllPagesRow[ContentTypeTitle];
            return $DisplayProducts01Title;
        }
        else if ($GetAllPagesRow[ContentTypeName] == 'information01') {
            DisplayInformation01DesignFunction();
        }
    }
}

显示数据的功能：

//DisplayProductsDesignFunction
function DisplayProducts01DesignFunction($DisplayProducts01Title) {
        echo "<div class='paddingcnt' id='services'>
        <div class='row-fluid'>
                <div class='span12'>
                        <div class='pricing'>
                                <div class='container'>
                                        <div class='row-fluid'>
                                                <h1>" . $DisplayProducts01Title . "</h1>
                                                <div class='row-fluid'>";
                                                        DisplayProducts01Function();
                                                        echo "</div>
                                                </div>
                                        </div>
                                </div>
                        </div>
                </div>
        </div>";
}

如何将函数 GetAllPages() 中的变量 $DisplayProducts01Title 用于函数 DisplayProducts01DesignFunction()？

【解决方案1】：

您需要在调用时将其传递给该函数。见下文：

//GetAllPages
function GetAllPages() {
  $GetAllPagesSql = "SELECT ContentPages.ContentPagesID, ContentType.ContentTypeName, ContentInformation.ContentInformationTitle, ContentPages.ContentPagesOrder FROM `ContentPages` INNER JOIN ContentType ON ContentPages.ContentTypeID = ContentType.ContentTypeID INNER JOIN ContentInformation ON ContentPages.ContentInformationID =   ContentInformation.ContentInformationID ORDER BY ContentPagesOrder";
  $GetAllPagesQuery = mysql_query($GetAllPagesSql);
  while (($GetAllPagesRow = \mysql_fetch_assoc($GetAllPagesQuery)) != false) {
      if($GetAllPagesRow[ContentTypeName] == 'products01') {
        // changes start here
        $DisplayProducts01Title = $GetAllPagesRow[ContentTypeTitle];  
        DisplayProducts01DesignFunction($DisplayProducts01Title);
        // changes end here
      }
      else if ($GetAllPagesRow[ContentTypeName] == 'information01') {
          DisplayInformation01DesignFunction();
      }
  }
}
