Encapsulate the php class to batch parse css into json format

Business requirements

我相信很多同学有过做一个自定义建站系统的想法，好比某空间的自定义拖拽组件，如果想要实现一个可视化建站系统，那CSS作为前端样式而言，是必须要存入到数据库中作为配置项的，所以，这里不可避免的需要对css做解析，我这里给出我的解析方法，当然还有很大的优化空间，这只是一个初版，实现了最原始的解析过程，希望大家拍砖。

Implementation method

Without further ado, let’s take a sneak peek at the code.

 /**

Css parsed into json class

class CsstoJson{

/**
* CSS batch import function
* @function ImportCss
* @param $data{xxx:XXX; yyy:YYY;}
* @Description Import CSS style structure into the database according to certain rules
* @return boolean
*/
public function ImportCss($post){
$data = str_replace("}","}&",$post); # Replace } with ｝&
$data =explode('&',$data); # & is used to cut each css Style sheet to array
array_pop($data); # Remove the last array element
$JsonData =self:: arrayToCss($data);
$length =1-count($JsonData);
$JsonData = substr($JsonData,$length,-1); # Intercept the last string
$JsonData = "{".$JsonData."}";
$JsonData = json_decode($JsonData,true ); # Convert to json array
return $JsonData;
}

/**
* CSS data styling function
* @function array_to_css
* @param $ArrayData is the css style data in format
*/
public function arrayToCss($ArrayData){
$ GetData=null;
//Traverse the passed array
foreach($ArrayData as $key => $arraydatas ){
$arraydatas = str_replace("{","&{",$arraydatas ); # Replace { in the transmitted data to facilitate subsequent string conversion
$arraydatas = explode('&',$arraydatas);
$jsondata = self::strToJson($arraydatas);
$GetData =$GetData.$jsondata.",";
}
return $GetData;
}

   /**   	* 解析数组里面的字符串操作 	* @function strToJson 	* $Strdata 二维数组，里面含有 	*/	public function strToJson($Strdata){    	//替换CSS数据名称    	$Strdata['0'] = str_replace(".","",$Strdata['0']);    	$Strdata['1'] = str_replace("{","",$Strdata['1']);    	$Strdata['1'] = str_replace("}","",$Strdata['1']);    	$temp = null;   	 	$StrdataChild =  explode(';',$Strdata['1']);   	 	array_pop($StrdataChild);    	foreach($StrdataChild as $key => $StrdataChilds){        	$StrdataChilds = explode(':',$StrdataChilds);                         # 分解每个类名下面的属性与具体数值的键值对        	$ProName = trim($StrdataChilds['0']);                                 # 去掉表单字段的空格，不然入库无法识别        	$jsondata = "\"".$ProName."\"".':'."\"".$StrdataChilds['1']."\",";    # 把类似height：10px这样的键值对分开成想要的数据结构        	$temp = $temp.$jsondata;                                              # 操作css的height等具体字段配置关系    	}    	$ClassName = trim($Strdata['0']);                                         # 去掉表单字段的空格，不然入库无法识别   		   		#获取当前字符串的长度    	$length =1-count($temp);    	#截取字符串最后    	$temp = substr($temp,$length,-1);    	#把当前所属分类名称加入到子集中    	$temp = "\""."classname"."\"".":"."\"".$ClassName."\"".",".$temp;    	return "\"".$Strdata['0']."\"".":"."{".$temp."}";	} 

}

$cssdata = ".wrapper .box{border:1px #e1e1e1 solid;}.wrapper .box .title{height:31px;border-bottom:1px #e1e1e1 solid;line-height:30px;}";$toJson = new CsstoJson();$reData = $toJson->ImportCss($cssdata);var_dump($reData);

Idea analysis

I have encapsulated it into a class here. What do the three functions handle?

In the first function importCss, we cut the batch css data into as many arrays according to the number of curly braces

Then pass the cut data to the second one function, and then traverse the array to process each set of data, and then cut it into an array according to the fact that each css statement ends with divide as the array separator

The third function is to split A good array is composed of json key-value pairs.

Summary

The reusability of functions is still not very high. I hope that if you have a better method, you are welcome to discuss it.
