    Example

    This function can be used in replacement of stripslashes_deep(). As it is a recursive function, when an array is given, it will remove slashes in all sub-arrays too.

    $arr = array(
	"Is your name O\'reilly?",
	"Person\'s Assets"
);

$arr = wp_unslash( $arr );
/*
 Outputs: 
 array(
      "Is your name O'reilly?",
      "Person's Assets"
 );
*/
