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 <constant>MYSQLI_ASSOC</constant>,
|
|
<constant>MYSQLI_NUM</constant>, or <constant>MYSQLI_BOTH</constant>.

As <function>mysqli_fetch_all</function> returns all the rows as an
|
|
array in a single step, it may consume more memory than some similar
|
|
functions such as <function>mysqli_fetch_array</function>, 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
|
|
<function>mysqli_fetch_all</function> should only be used in those
|
|
situations where the fetched result set will be sent to another
|
|
layer for processing.
