CSS update class instance implemented by php, phpcss update instance

The example in this article describes the CSS update class implemented in PHP and its usage, which is very practical. Share it with everyone for your reference. The details are as follows:

CSSUpdate.class.php class file is as follows:

<&#63;php 
/** css 更新类,更新css文件内图片的版本 
*  Date:  2013-02-05 
*  Author: fdipzone 
*  Ver:  1.1 
* 
*  Func: 
*  update(); 
* 
*  Ver:  1.1 增加search_child参数,可遍历子文件夹 
*/ 
 
class CSSUpdate{ 
 
  private $csstmpl_path = null; 
  private $css_path = null; 
  private $replacetags = array(); 
  private $search_child = false; 
  private $convert_num = 0; 
  private $is_ready = 0; 
 
  /** 初始化 
  * @param String $csstmpl_path css模版路径 
  * @param String $css_path   css目标路径 
  * @param Array  $replacetags 需要替换的图片类型 
  * @param boolean $search_child 是否遍历子文件夹,默认false 
  */ 
  public function __construct($csstmpl_path, $css_path, $replacetags=array(), $search_child=false){ 
    if(!is_dir($csstmpl_path) || !is_dir($css_path) || !$replacetags){ 
      $this->is_ready = 0; 
    }else{ 
      $this->csstmpl_path = $csstmpl_path; 
      $this->css_path = $css_path; 
      $this->replacetags = $replacetags; 
      $this->search_child = $search_child; 
      $this->is_ready = 1; 
    } 
  } 
 
  /** 更新css文件 */ 
  public function update(){ 
    if($this->is_ready==0){ 
      $this->response('csstmpl or csspath or replacetags error'); 
      return ''; 
    } 
    $this->traversing($this->csstmpl_path); 
    $this->response('covert num:'.$this->convert_num); 
  } 
 
  /** 遍历文件夹 
  * @param String $path 文件路径 
  */ 
  private function traversing($path){ 
    $handle = opendir($path); 
    while(($file=readdir($handle))!==false){ 
      if($file!='..' && $file!='.'){ 
        $curfile = $path.'/'.$file; 
         
        if(is_dir($curfile)){  // folder 
          if($this->search_child){  // 需要遍历子文件夹 
            $this->traversing($curfile); 
          } 
        }elseif($this->checkExt($curfile)){ // css file 
          $dfile = str_replace($this->csstmpl_path, $this->css_path, $curfile); 
          $this->create($curfile, $dfile); 
          $this->response($curfile.' convert to '.$dfile.' success'); 
          $this->convert_num ++; 
        } 
      } 
    } 
    closedir($handle); 
  } 
 
  /** 检查文件后缀 */ 
  private function checkExt($file){ 
    $name = basename($file); 
    $namefrag = explode('.', $name); 
    if(count($namefrag)>=2){ 
      if(strtolower($namefrag[count($namefrag)-1])=='css'){ // css文件 
        return true; 
      } 
    } 
    return false; 
  } 
 
  /** 替换模版内容,写入csspath 
  * @param String $tmplfile 模版文件 
  * @param String $dfile  目标文件 
  */ 
  private function create($tmplfile, $dfile){ 
    $css_content = file_get_contents($tmplfile); 
    foreach($this->replacetags as $tag){ 
      $css_content = str_replace($tag, $tag."&#63;".date('YmdHis'), $css_content); 
    } 
    if(!is_dir(dirname($dfile))){  // 生成目标路径 
      mkdir(dirname($dfile), 0755, true); 
    } 
    file_put_contents($dfile, $css_content, true); 
  } 
 
  /** 输出 */ 
  private function response($content){ 
    echo $content."<br>"; 
  } 
} 
&#63;>

The demo sample program is as follows:

<&#63;php 
require_once "CSSUpdate.class.php"; 
 
define('ROOT_PATH', dirname(__FILE__)); 
$css_path = ROOT_PATH.'/css'; 
$csstmpl_path = ROOT_PATH.'/csstmpl'; 
$replacetags = array('.png', '.jpg', '.gif'); 
 
$cssobj = new CSSUpdate($csstmpl_path, $css_path, $replacetags); 
$cssobj->update(); 
&#63;>

I hope this article will be helpful to everyone’s learning of PHP programming.

PHP changes the display content through css. If the answer is correct, an additional 50 will be added

How can php dynamically obtain the data in css, for example: dynamically change the width and height

This should be obtained using javascript on the html page. How do you use your server language to obtain the css of the html page running in other browsers.

document.write( document.getElementById( "#test" ).style.backgroundColor);

should be obtained like this. If your server insists on needing this information, use ajax or a form to pass it back to Server php page
