#47582 [NEW]: system(), passthru() do not work online, but work with command line

From: liangc dot mu at gmail dot com Operating system: RedHat Enterprise 5.2 PHP version: 5.2.9 PHP Bug Type: *General Issues Bug description: system(), passthru() do not work online, but work with command line Description: ------------ Basically, my test.php contains: <?php #$cmd="/usr/local/genome/gmap/gmap-2009-02-04/bin/gmap -v"; $cmd="/usr/local/genome/gmap/gmap-2009-02-04/bin/gmap -d oryza_sativa_rap_4 -n 1000 -k 2000 -A -B 2 sample_chlamy.fasta.valid >out"; system($cmd,$exeReturn); #exec($cmd); echo $cmd."<br/>"; echo $exeReturn."<br/>"; ?> (1) In command line, when I type "php test.php", I met success in executing the gmap program and get the out result. (2) However, through the web server, the system command is always not executed. I have another server that have the identical settings (such as the same httpd.conf, php.ini), the test.php code can be executed through the Internet and the command line.
