php reads php configuration file

1. The content of the configuration file my.php is as follows:

2. $config->installed = true;
   $config->debug = false;
   $config->requestType = 'GET';
   $config->db-> ;host = '16.112.89.126:3306';
   $config->db->name = 'test';
   $config->db->user = 'root';
   $config->db ->password = 'pwd';
   $config->db->prefix = 'zt_';
   $config->webRoot = getWebRoot();
   $config->default->lang = ' zh-cn';
   $config->mysqldump = 'D:beanGoumysqlbinmysqldump.exe';

3. Code to read the configuration file:

function get_config($file, $ini, $type="string"){
 if(!file_exists($file)) {
 echo 'file not exist';
 return false;
 }
 $str = file_get_contents($file);
 if ($type=="int"){
 $config = preg_match("/".preg_quote($ini)."=(.*);/", $str, $res) ;
 return $res[1];
 }
 else{
// $config = preg_match("/".preg_quote($ini)."="(.*)";/", $str, $res) ;
 $config = preg_match("/".preg_quote($ini)."s*=s*"(.*)";/", $str, $res);
 if($res[1]== null){
 $config = preg_match("/".preg_quote($ini)."s*=s*'(.*)';/", $str, $res);
// $config = preg_match( "/".preg_quote($ini)."='(.*)';/", $str, $res);
 }
 return $res[1];
 }
 }

The code corresponding to the two lines of comments is from the Internet. Because there are spaces, it cannot be read. I made some modifications myself. After the modification, it can be read even if there are spaces.

Note: If the configuration file my.php has comments, if there is something like this

//$config->db->host = '16.112.89.126:3306';

, this method will read the comment content, so if it is useless, the last Easy to delete,
