mysqli_fetch_all

MYSQLI_FETCH_ALL(3)							 1						       MYSQLI_FETCH_ALL(3)

mysqli_result::fetch_all - Fetches all result rows as an associative array, a numeric array, or both

       Object oriented style

SYNOPSIS

       mixed mysqli_result::fetch_all ([int  $resulttype = MYSQLI_NUM])

DESCRIPTION

       Procedural style
       mixed mysqli_fetch_all (mysqli_result  $result, [int  $resulttype = MYSQLI_NUM])

       mysqli_fetch_all(3) fetches all result rows and returns the result set as an associative array, a numeric array, or both.

PARAMETERS

	      o $
		result	 -Procedural   style   only:   A   result   set   identifier   returned   by  mysqli_query(3),	mysqli_store_result(3)	or
		mysqli_use_result(3).

	      o $resulttype
		- This optional parameter is a constant indicating what type of array should be produced from the current row data.  The  possible
		values for this parameter are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH.

RETURN VALUES

	Returns an array of associative or numeric arrays holding result rows.

MYSQL NATIVE DRIVER ONLY

	Available only with mysqlnd.

	As  mysqli_fetch_all(3)  returns all the rows as an array in a single step, it may consume more memory than some similar functions such as
       mysqli_fetch_array(3), which only returns one row at a time from the result set. Further, if you need to iterate over the result  set,  you
       will need a looping construct that will further impact performance. For these reasons mysqli_fetch_all(3) should only be used in those sit-
       uations where the fetched result set will be sent to another layer for processing.
