Write an array down the configuration file,& symbol Why did you become &amp

Writes an array to the configuration file,& symbol why &

$config _arr = Var_export ($configdata, true);
$config _txt = " file_put_contents (' config.ini.php ', $config _txt);


$config _arr is an array with the & symbol in the array value and writes it to config.ini.php after the,& symbol becomes &

Is there a way to keep it the same?
------to solve the idea----------------------
This is not possible, you should have done it in the first HTML escape

$a = Array (' a ' = = ' &abc ');
$s =  var_export ($a, 1);
Echo $s;

Array (
  ' A ' = ' &abc ',
)

References:

this solves the problem of character escaping when the parameter is received.
Now there is one more question:
The ConfigData array has character backslashes \, after this sentence
$config _arr = Var_export ($configdata, true);

After writing to the configuration file, the backslash becomes \ \ How to resolve

Stripslashes () Use this method to turn back.
