javascript - 尝试创建一个生成 javascript 文件的 php foreach 循环

Question

所以我有这个脚本，我试图在 php 中创建一个 filelist.js 文件，这是代码:

//CREATE fileslist.js
$thumbssize = "1";
$moviesize= "1";
$thumbarray = array_slice(scandir($tpath), 2);

echo print_r($thumbarray) . "<br/>";

if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
    $script="
fileList = {};
fileList[\"thumbs\"] = {};
fileList[\"movies\"] = {};
fileList[\"title\"]=\"{$foldername}\";";

foreach($thumbarray as $item) {
print "fileList[\"thumbs\"][1]=["$item['0']","$item['2']","$item['3']","$item['4']","$item['5']","$item['6']"];";
    }

$script2 = "    
fileList[\"thumbs\"][\"size\"]={$thumbssize};
fileList[\"thumbs\"][\"size\"]={$moviesize};";

//$script = preg_replace('/\s\s+/', ' ', $script);
$scriptName= $_SERVER['DOCUMENT_ROOT'] . "/{$foldername}/assets/js/filelist.js";
file_put_contents($scriptName, trim($script . $script2) . "\n", FILE_APPEND);
echo "Generating filelist.js</br>";
    }

这是数组的示例输出:

Array ( [0] => 863_example_r003.mp4 [1] => 863_example_r004.mp4 [2] => 863_example_r005.mp4 [3] => 863_example_r006.mp4 [4] => 863_example_r007.mp4 ) 1

这是当前的 filelist.js 输出:

fileList = {};
fileList["thumbs"] = {};
fileList["movies"] = {};
fileList["title"]="test7";

fileList["thumbs"]["size"]=1;

fileList["thumbs"]["size"]=1;

到目前为止，它正在做我想要的事情，除了我无法弄清楚如何创建 foreach 循环来生成这种类型的输出:

fileList = {};
fileList["thumbs"] = {};
fileList["movies"] = {};
fileList["title"]="863-example";
fileList["thumbs"][1]=["863_example_r048.mp4","863_example_r049.mp4","863_example_r050.mp4","863_example_r051.mp4","863_example_r052.mp4","863_example_r053.mp4"];
fileList["thumbs"][2]=["863_example_r054.mp4","863_example_r055.mp4","863_example_r056.mp4","863_example_r057.mp4","863_example_r058.mp4","863_example_r059.mp4"];
fileList["thumbs"][3]=["863_example_r060.mp4","863_example_r061.mp4","863_example_r062.mp4","863_example_r003.mp4","863_example_r063.mp4","863_example_r064.mp4"];
fileList["thumbs"][4]=["863_example_r065.mp4","863_example_r004.mp4","863_example_r067.mp4","863_example_r068.mp4","863_example_r069.mp4","863_example_r070.mp4"];
fileList["thumbs"][5]=["863_example_r005.mp4","863_example_r071.mp4","863_example_r072.mp4","863_example_r073.mp4","863_example_r074.mp4","863_example_r006.mp4"];
fileList["thumbs"][6]=["863_example_r075.mp4","863_example_r076.mp4","863_example_r077.mp4","863_example_r078.mp4","863_example_r007.mp4","863_example_r079.mp4"];
fileList["thumbs"][7]=["863_example_r080.mp4","863_example_r081.mp4","863_example_r082.mp4","863_example_r008.mp4","863_example_r083.mp4","863_example_r084.mp4"];
fileList["thumbs"][8]=["863_example_r085.mp4","863_example_r086.mp4","863_example_r009.mp4","863_example_r087.mp4","863_example_r088.mp4","863_example_r089.mp4"];

[1]、[2]、[3]指的是页码，如上例所示，每页需要有 6 条内容

感谢您的反馈。就在一分钟前，我改进了代码并在本地主机中进行了测试。以下是给出结果的更改后的代码:

$script1 = "";
$i       = 0;
$j       = 0;
$inrow   = 6; // files in row
foreach($thumbarray as $item => $itemv) {

  // beginning of the row
  if($j % $inrow == 0){ 
    $script1 .= "\nfileList[\"thumbs\"][".($i+1)."]=[";
  }

  $script1 .= "\"" . $itemv . "\","; // add filename "863_example_r048.mp4",

  // end of the row
  if(($j + $inrow + 1) % $inrow == 0){
    // Delete comma at end of row
    if(substr($script1,-1) == ","){ 
      $script1 = substr($script1, 0, strlen($script1) - 1);
    }
    $script1 .= "];";
  }
  if($j % $inrow == 0){ 
    $i++;
  }
  $j++;
}

测试结果如下:
