Bug #8248 Updated: system function cannot support "&"

ID: 8248 Updated by: elixer Reported By: erwinba@163.net Old-Status: Open Status: Closed Bug Type: Program Execution PHP Version: 4.0.3 Assigned To: Comments: This is not a bug. From the manual (http://www.php.net/manual/en/function.exec.php): "Note also that if you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends." Try changing your code from: system("/mycommand/myprog &"); to: system("/mycommand/myprog > /dev/null &"); Sean Previous Comments: --------------------------------------------------------------------------- [2001-02-01 15:21:11] elixer@php.net Have you tried disabling safe_mode? The command will not be stripped of "questionable" characters if safe_mode is disabled. Sean --------------------------------------------------------------------------- [2000-12-14 03:50:32] erwinba@163.net the "system", "exec" or "passthru" function cannot support the background process, such as : system("/mycommand/myprog &"); The functions will not continue untill "/mycommand/myprog" is finished, but I wish the PHP can return at once to continue after the myprog is started not ended. --------------------------------------------------------------------------- ATTENTION!
