How PHP escape symbols are converted

How does the PHP escape symbol convert?
The string returned in PHP is in this format [\ "1\", \ "2\", \ "3\", \ "4\"] I would like to replace ["1", "2", "3", "4"] format

------Solution--------------------

PHP Code

$str = ' [\ ' 1\ ', ' 2\ ', ' 3\ ', ' 4\ '] '; Echo preg_replace ('/\\\/', ', $str);
------Solution--------------------
It may be that you have automatically escaped the input data (MAGIC_QUOTES_GPC) in the configuration of PHP, you can use Stripslashes () to remove the escape character \

  
  
  

   
   
   PHP Code
   
   
   
$input = ' [\ ' "1\", \ "2\", \ "3\", \ "4\"] '; Echo stripslashes ($input);
