PHP Cake\Database Query::bufferResults Examples

bufferResults() public method

When enabled the results returned by this Query will be buffered. This enables you to iterate a result set multiple times, or both cache and iterate it. When disabled it will consume less memory as fetched results are not remembered for future iterations. If called with no arguments, it will return whether or not buffering is enabled.

public bufferResults ( boolean | null $enable = null ) : boolean | $this
$enable	boolean | null	whether or not to enable buffering
return	boolean | $this
