I'm writing a shell script that uses error_log function to log some data, but it echos the error message to the output without logging the message to the log file.
"the log file"...
*WHAT* log file?
A shell script has no pre-determined log file, really.
Actually, it's almost for sure STDOUT at that point, or maybe STDOUT, but I doubt it. If you were coding PHP engine and needed to send error output somewhere under shell circumstances, you'd think STDOUT would be "it" right?...
So you can probably re-direct 2 (STDOUT) to somewhere to get the error_log output where you want it.
I think in most shells that turns into: test.php 2> /var/log/test YMMV It's up to you to figure out re-directs in your shell of choice. Good luck.
You should probably use can use set_error_handler to trap errors -- though that will not catch error_log output, I don't think.
You can also use set_error_reporting() to get rid of errors entirely, though that's not recommended.
I don't really need it to log into a file, but I wanted to prevent it from echoing to the screen.
So I guess there's no way to prevent from error_log() (using defaults) to echo to the screen (STDOUT).
error_reporting() affects on errors produced by PHP itself. I tried to set it to 0 before the call, but it didn't help.
set_error_handler() affects on trigger_error() and not on error_log().
It seems that the extern lib I use should use trigger_error() (or user_error()) function instead, which is the traditional way to report user-defined errors.
Thanks for your help all...
