PHP is to remove all the html,js,css in the Web page, the annotation implementation method _php instance

As shown below:

$search = Array ("' <script[^>]*?>.*?</script> ' si",//Remove JavaScript
 "' <style[^>]*?>.*?) </style> ' Si ',  //Remove CSS '
 <[/!] *? [^<>]*?> ' Si ',      //Remove HTML Tags
 "' <!--[/!] *? [^<>]*?> ' Si ',//      Remove comment Mark
 "' ([RN]) [s]+ '",  //Remove white space character
 "' & (quot| #34); ' I ",  //Replace HTML entity

 " ' & (amp| #38); ' I ",
 " ' & (lt| #60); ' I ",
 " ' & (gt| #62); ' I ",
 " ' & (nbsp| #160); ' I ",
 " ' & (iexcl| #161); ' I ",
 " ' & (cent| #162); ' I ",
 " ' & (pound| #163); ' I ",
 " ' & (copy| #169); ' I ",
 " ' &# (d+); ' E ");   Run as PHP code
 
$replace = Array ("",
 "", ""
 ,
 "" ",
 " \1 ",
 " \ "",
 "&",
 "<" , 
 ">",
 "" ",
 chr (161),
 Chr (162),
 Chr (163),
 Chr (169),
 " Chr (\1) ");
$document for strings to be processed if the source is a file can $document = file_get_contents ($filename);
$out = Preg_replace ($search, $replace, $document);

You can also use PHP's built-in function strip_tags () to clear html,js, annotations, and so on.
