php5 cli: no output

Question

Hi, i've got a php script that runs on the command line. To improve it's performance, i would like to completely suppress it's output.

How can I do that?

Thanks!

Answer 1

function ob_esity($b) { return ''; }
ob_start('ob_esity');

Answer 2

Not sure about performance but you can use

php -q myscript.php > /dev/null

Answer 3

One way would be to call ob_start() to turn on output buffering, and periodically call ob_clean() if you really don't want the output (or use a dummy ob_start() callback which does nothing).

Not sure how much of a performance gain this would be, as internally, PHP is still processing the output, except it goes into a buffer rather than to stdout.

If you've got a lot of diagnostic output you want to prevent, than it might be more effective to refactor your code to allow that to be suppressed by an application option.

Answer 4

Using > /dev/null is not enough?

Answer 5

If you have access to the script replace all echo with //echo. Perfect performance increase, but you will need to check multi-line echo statements.

Answer 6

fclose(STDOUT);

This will work cross platform as the first line in the PHP script.
