<p class="para">
As <span class="function"><strong>mysqli_fetch_all()</strong></span> returns all the rows as an
array in a single step, it may consume more memory than some similar
functions such as <span class="function"><a href="mysqli-result.fetch-array.html" class="function">mysqli_fetch_array()</a></span>, 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
<span class="function"><strong>mysqli_fetch_all()</strong></span> should only be used in those
situations where the fetched result set will be sent to another
layer for processing.
