獲取file_put_content到一個文件夾

Question

我想把我的文件從file_put_contents的文件夾可以有人幫助我。

$invoegen_titel=$_POST['titel_form']; 
$invoegen_datum=$_POST['datum']; 
$invoegen_tekst=$_POST['tekst']; 

$html_tekst= $invoegen_titel."</h1>"."<br>"."<p>".$invoegen_datum."</p>"."<br>"."<p>".$invoegen_tekst."</p>"; 
$previous = $_SERVER['HTTP_REFERER']; 
$folder='blog'; 
var_dump(file_put_contents($folder."/".time().".html","<h1>".$invoegen_titel."</h1>"."<br>"."<p>".$invoegen_datum."</p>"."<br>"."<p>".$invoegen_tekst."</p>")); 

Answer 1

1. 確保該目錄是存在的。如果目錄不存在，file_put_contents不會創建該目錄。

2. 請指出您在代碼中遇到的問題。

3. 改變這些部件

   $folder = time(); //make sure that time() returns string $folder = "blog/".$folder.'.html'; file_put_contents($folder, $html_tekst); var_dump(file_get_contents($folder));

Answer 2

使用此：

$lifeTime = 5; // life time, seconds 

    $cached = TRUE; 

    $config = array(
    'group'=>'default', // dir 
    'id' => '1',   // id cache 
    'echo' => TRUE,  // echo or return 
    'log'=>false,  // echo log, or not 
    'ext' => 'js'  // extention cache file, default .html 
); 

    $CacheFile = new CacheFile('/usr/cache/', $cached); 
    $CacheFile->config($config, $lifeTime); 
    if (!$CacheFile->start()){ 
     echo $invoegen_titel."</h1>"."<br>"."<p>".$invoegen_datum."</p>"."<br>"."<p>".$invoegen_tekst."</p>"; 

     $CacheFile->end(); 
    } 

PHP類：

class CacheFile{ 

    private $cacheDir = ''; 
    private $cacheSubDir = ''; 
    private $fileName = ''; 
    private $cache = false; 
    private $lifeTime = 0; 
    private $echo = true; 
    private $group = true; 
    private $log = true; 
    private $fileExt = 'html'; 


    public function __construct($cacheDir, $cache){ 
     $this->cacheDir = $cacheDir; 
     $this->cache = $cache; 
    } 

    private function createdPatch(){ 
     if ($this->cache){ 
      if (!is_dir($this->cacheSubDir)){ 
       mkdir($this->cacheSubDir, 0777, true); 
      } 
      chmod($this->cacheSubDir, 0755); 
     } 
    } 
    private function getSubDir($keyType, $keyValue){ 
     return (($keyType != '')?($keyType.'/'):'').mb_substr($keyValue, 0, 1)."/".mb_substr($keyValue, 1, 1)."/".mb_substr($keyValue, 2, 1)."/"; 
    } 

    private function getCacheName($key){ 
     return md5($key).".".$this->fileExt; 
    } 

    public function config($conf = array('group'=>'post', 'id' => '0', 'echo' => TRUE), $time = 31536000){ 
     $this->group = $conf['group']; 
     $this->cacheSubDir = $this->cacheDir.$this->getSubDir($conf['group'], md5($conf['id'])); 
     $this->fileName = $this->getCacheName($conf['group'].$conf['id']); 
     $this->lifeTime = $time; 
     if (isset($conf['echo'])) 
      $this->echo = $conf['echo']; 
     if (isset($conf['log'])) 
      $this->log = $conf['log']; 
     if (isset($conf['ext'])) 
      $this->fileExt = $conf['ext']; 


    } 

    public function start(){ 
     if ($data = $this->get()) { 
      if ($this->echo){ 
       echo $data; 
       return true; 
      }else{ 
       return $data; 
      } 
     } 
     ob_start(); 
     ob_implicit_flush(false); 
     return false; 
    } 

    function end(){ 
     $data = ob_get_contents(); 
     ob_end_clean(); 
     if ($this->cache){ 
      $this->save($data.(($this->log)?'<!-- c:'.$this->group.':('.date("Y-m-d H:i:s", (time()+$this->lifeTime)).'/'.date("Y-m-d H:i:s").') -->':"")); 
     } 
     $return = $data.(($this->log)?'<!-- g:'.$this->group.':('.date("Y-m-d H:i:s", (time()+$this->lifeTime)).'/'.date("Y-m-d H:i:s").') -->':""); 
     if ($this->echo){ 
      echo $return; 
      return true; 
     } 
     return $return; 
    } 

    public function get(){ 
     if (!file_exists($this->cacheSubDir.$this->fileName)) 
      return false; 

     if (time() >= filemtime($this->cacheSubDir.$this->fileName) + $this->lifeTime){ 
      unlink($this->cacheSubDir.$this->fileName); 
      return false; 
     } 

     if ($this->cache && file_exists($this->cacheSubDir.$this->fileName)) 
      if ($data = file_get_contents($this->cacheSubDir.$this->fileName, false)) 
       return $data; 
     return false; 
    } 

    public function remove(){ 

     if (file_exists($this->cacheSubDir.$this->fileName)){ 
      echo unlink($this->cacheSubDir.$this->fileName); 
      return true; 
     } 
     return false; 

    } 

    public function save($data){ 
     $this->createdPatch(); 
     if (file_put_contents($this->cacheSubDir.$this->fileName, $data, LOCK_EX)) 
      return true; 
     return false; 
    } 

} 

Answer 3

我固定它

<?php $list = file_get_contents('list.json'); $list = json_decode($list, true); $selector = $_POST['selector']; $d_or_t = $_POST['d_or_t']; if (isset($selector) && isset($d_or_t)) { // overwrite the selected domain of the list with the new value if they are not empty if ($d_or_t == "domain") { $list[$selector]['domain'] = $_POST['new']; } if ($d_or_t == "template") { $list[$selector]['template'] = $_POST['new']; } /*else { echo '<script type="text/javascript">alert("U bent vergeten een veld in te voelen!");</script>'; }*/ // store the new json } ?>
