Speeding up command line scripts

[Snyke]

Hi.
I have a command line script which works really fine, the only problem
is that it take *really* long for the first output to be printed on
screen.
Since I also get some HTTP headers I'm suspecting that some sort of
output buffering is used.
How can I tell PHP to flush the buffer automatically (without using
flush(); after every print or echo) and to remove the headers?

Snyke, why do you have http headers in command line php. It is not
needed. At a minimum, you can put in some conditional statements to
take them out if running from command line (there are ways to
auto-detect running from command line vs. from browser).

Once that is done, it is much easier to isolate the problem.

By the way, I have a ton of command line php code, and never seen this
problem, so I suspect something is going on before the first echo...
you may want to take out the code, or put in some timing echo
statements.

You can disable outputbuffering in the php.ini file (output_bufferi ng = off)
and also specify if you want php to flush each time an echo or print is
encountered.(im plicit_flush = on)

But It sounds like something else is 'wrong' if it takes that long...

to tell php to omit the headers:
php -q script.php
or if you've got an embedded interpreter directive:
#!/usr/bin/php -q

or if you're still using Microsoft Operating systems:
php.exe -q script.php

to flush the output,
flush();

(note this will only flush up to the last newline char)

Just throw an 'ob_end_flush() ;' at the start of your script... NOT after
every echo or print.
