试图创建一个PHP foreach循环生成的JavaScript文件

Question

所以我有这样的脚本，我尝试从PHP中创建一个filelist.js文件下面的代码：

//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>"; 
    } 

这下面是示例输出数组：

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filelist.js输出，因为它代表现在：

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

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

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

这么涨ü NTIL这一点它做我想要什么，除了我无法弄清楚如何使foreach循环产生这种类型的输出：

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"]; 

的[1]，[2]，[3]是指一个页码并且需要有每页6项如上

感谢您的反馈意见。就在一分钟前，我精炼了代码并在我的本地主机上测试了它。这里是改变的代码，给出结果：

$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++; 
} 

下面是测试结果：

fileList["thumbs"][1]=[".AndroidStudio1.3",".ICEauthority",".PlayOnLinux",".Skype",".Xauthority",".adobe"]; fileList["thumbs"][2]=[".android",".audacity-data",".bash_history",".bashrc",".bibletime",".cache"]; fileList["thumbs"][3]=[".claws-mail",".config",".dbus",".directory",".dmrc",".dosbox"]; fileList["thumbs"][4]=[".emacs",".esd_auth",".fltk",".fontconfig",".fonts",".fonts.conf"]; fileList["thumbs"][5]=[".frozen-bubble",".gimp-2.8",".gnome",".gnome2",".gnome2_private",".gnupg"]; fileList["thumbs"][6]=[".gstreamer-0.10",".gtkrc-2.0",".gvfs",".icewm",".inputrc",".ivy2"]; fileList["thumbs"][7]=[".java",".jsword",".kde",".kde4",".kismet",".local"]; fileList["thumbs"][8]=[".macromedia",".mozilla",".mplayer",".mtpaint",".opera",".pki"]; fileList["thumbs"][9]=[".profile",".putty",".pyhistory",".qt",".remmina",".sbt"]; fileList["thumbs"][10]=[".skel",".ssh",".streamtuner",".sword",".themes",".thumbnails"]; fileList["thumbs"][11]=[".thunderbird",".vnc",".wine",".xboardrc",".xdg_menu_cache",".xim.template"]; fileList["thumbs"][12]=[".xinitrc.template",".xiphos",".xscreensaver",".xsession-errors",".xsession-errors-192.168.1.101:1",".xsession-errors-192.168.1.103:1"]; fileList["thumbs"][13]=[".xsession-errors-:0",".xsession-errors-:1",".y2log",".y2usersettings","20150901_134031.jpg","281436_wpmu-dev-dashboard-3.5.3.zip"]; fileList["thumbs"][14]=["Android","AndroidStudioProjects","Bible Analyzer User Modules","Calibre Library","Desktop","Documents"]; fileList["thumbs"][15]=["Downloads","Java","Kismet-20141124-23-54-29-1.alert","Kismet-20141124-23-54-29-1.gpsxml","Kismet-20141124-23-54-29-1.nettxt","Kismet-20141124-23-54-29-1.netxml"]; fileList["thumbs"][16]=["Kismet-20141124-23-54-29-1.pcapdump","Movies","Music","Phpgtk","Pictures","PlayOnLinux's virtual drives"]; fileList["thumbs"][17]=["Public","Templates","Videos","VirtualBox VMs","WPMUDEV_PLUGINS.zip","battery"]; fileList["thumbs"][18]=["bibleanalyzer","bibledesktop-2.0-beta","bin","ca.key","deklaracia.jpg","deklaracia2.jpg"]; fileList["thumbs"][19]=["dfc","http:⁄⁄www.biblestudytools.com⁄niv⁄.desktop","konq","projects","public_html","scala"]; fileList["thumbs"][20]=["somefile","somefile.txt","viber","wget-log","wp-cron.php?import_key=d&import_id=20&action=processing","Запис0003.amr"];

Answer 2

您需要更改以下部分

$index = 1; 
foreach($thumbarray as $item) { 
$script .= "fileList[\"thumbs\"][$index]= ".json_encode($item).";" ; 
$index++; 
} 

Answer 3

你需要两个索引的例子。 $ i每次在$ inrow时间内被正确地删除，其余的为0.如果你想要6行文件，那么$ i应该比每次增加$ j少6倍。这样$当$ j为6,12,18,24等，您将需要发挥一点点的代码我会改变......

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

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

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

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