PHP implementation of multidimensional array and multidimensional array to a one-dimensional array method _php tips

This article illustrates the method of PHP implementing multidimensional array and multidimensional array to one-dimensional array. Share to everyone for your reference. The implementation methods are as follows:

/** 
* @method multidimensional array spin string 
* @param type $array 
* @return type $srting 
* @author Yanhuixian 
* * function arraytostring ($arr) { 
if (Is_array ($arr)) {return 
implode (', ', Array_map (' arraytostring ', $arr)); 
} return 
$arr; 
} 
/** 
* @method multidimensional array into one-dimensional array 
* @staticvar array $result _array 
* @param type $array 
* @return Type $array c17/>* @author Yanhuixian 
* 
/function Multi2array ($array) { 
static $result _array = Array (); 
foreach ($array as $key => $value) { 
if (Is_array ($value)) { 
array_multi2array ($value); 
} 
else 
$result _array[$key] = $value; 
} 
return $result _array; 
}
