Hello
I run a simple php file as:
<?php
$result=system( "atq",$paramete r);
echo '<br>result='.$ result;
echo '<br>parameter= '.$parameter;
//phpinfo();
?>
run it on command line can get the parameter value as 0,but if use
browser to run it,the parameter value is 1,Why?
Note:I had set the user and group in httpd.conf.if change as
$result=system( "ls",$parameter );,then can get the parameter value as 0

Since you haven't set the value of $parameter anywhere I'm not sure
why you'd expect it have any particular value.

When run on the command line, it is running under the userid that you
are logged in with.
When run from a browser, the web server (apache?) is running it under
its userid. Possibly this latter userid does not have the correct
authority?

Yes,I know your meaning,My web server is apache,I had changed the user
and group as Test_bench,thse user that I logged in Linux is Test_bench
too,so,I don't think this issue is about User Setting.
