在我的网站上显示谷歌图片？ （修订版）

Question

所以基本上我试图根据存储在数组中的单词从谷歌图像在我的网站上显示图像。现在，我有这个简单的PHP代码加载到我的.txt文件中，将一个随机单词放入$ lines数组，然后从中挑选一个随机单词。

<?php $lines = file('things.txt');
echo $lines[array_rand($lines)];
?>

然后我直接从谷歌获得此代码，对代码中指定的特定单词进行图像搜索，然后将结果显示在您的网页上。

<script src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">

      google.load('search', '1');

      var imageSearch;

      function addPaginationLinks() {

        // To paginate search results, use the cursor function.
        var cursor = imageSearch.cursor;
        var curPage = cursor.currentPageIndex; // check what page the app is on
        var pagesDiv = document.createElement('div');
        for (var i = 0; i < cursor.pages.length; i++) {
          var page = cursor.pages[i];
          if (curPage == i) { 

          // If we are on the current page, then don't make a link.
            var label = document.createTextNode(' ' + page.label + ' ');
            pagesDiv.appendChild(label);
          } else {

            // Create links to other pages using gotoPage() on the searcher.
            var link = document.createElement('a');
            link.href="/image-search/v1/javascript:imageSearch.gotoPage("+i+');';
            link.innerHTML = page.label;
            link.style.marginRight = '2px';
            pagesDiv.appendChild(link);
          }
        }

        var contentDiv = document.getElementById('content');
        contentDiv.appendChild(pagesDiv);
      }

      function searchComplete() {

        // Check that we got results
        if (imageSearch.results && imageSearch.results.length > 0) {

          // Grab our content div, clear it.
          var contentDiv = document.getElementById('content');
          contentDiv.innerHTML = '';

          // Loop through our results, printing them to the page.
          var results = imageSearch.results;
          for (var i = 0; i < results.length; i++) {
            // For each result write it's title and image to the screen
            var result = results[i];
            var imgContainer = document.createElement('div');
            var title = document.createElement('div');

            // We use titleNoFormatting so that no HTML tags are left in the 
            // title
            title.innerHTML = result.titleNoFormatting;
            var newImg = document.createElement('img');

            // There is also a result.url property which has the escaped version
            newImg.src="/image-search/v1/result.tbUrl;"
            imgContainer.appendChild(title);
            imgContainer.appendChild(newImg);

            // Put our title + image in the content
            contentDiv.appendChild(imgContainer);
          }

          // Now add links to additional pages of search results.
          addPaginationLinks(imageSearch);
        }
      }

      function OnLoad() {

        // Create an Image Search instance.
        imageSearch = new google.search.ImageSearch();

        // Set searchComplete as the callback function when a search is 
        // complete.  The imageSearch object will have results in it.
        imageSearch.setSearchCompleteCallback(this, searchComplete, null);

        // The Term to Search, I want this to be the random word generated in the $lines array
        imageSearch.execute("pickles");

        // Include the required Google branding
        google.search.Search.getBranding('branding');
      }
      google.setOnLoadCallback(OnLoad);
    </script>

现在我无法弄清楚我的生活如何使上面的代码基于我之前生成的随机单词我的php代码进行搜索。我尝试了各种各样的方法，但是我只是没有足够的编码经验来尝试自己解决这个问题。

希望这个有意义，谢谢你们
