I have a mysql query that returns 20 results from a table of 110,000,000. I would like to shuffle these before echoing them out using php.
Is it faster to use
ORDER RAND()
or
shuffle the array in php somehow?
Depending on the amount of results you’re pulling back from MySQL,
ORDER BY RAND()will be faster.If you’re only returning 20 like you say, the performance differences will be negligible.
You could always test it out and see which is better for you, to shuffle an array in PHP you would use
shuffle().
