All exec related php function (like exec, shell_exec, popen, ..) all sefgault. php sample code (test.php) <?php $s=shell_exec("ls"); echo $s ?> result: # php test.php [1] Segmentation fault I added some debug code to the internal shell_exec function PHP_FUNCTION(shell_exec) { FILE *in; size_t total_readbytes; zval **cmd; char *ret; php_stream *stream; if (ZEND_NUM_ARGS()!=1 || zend_get_parameters_ex(1

问题 Is there any alternative for PHP exec(), shell_exec(), system(), passthrough() functions? As all these functions have security risk, need a way to execute server commands without using any of these functions.

But as per website requirement, I need to execute some external commands like server ssh commands through php script. So, if there are any alternative ways to achieve same then please reply back to me.

问题 I am writing a PHP script for the GUI of a Cent OS server. For testing purposes I have set up the Apache as localhost. Cent OS does not automount a connected USB device. In PHP I need to check if a USB device is plugged in then mount it and list the file content for the user. This is quite simple in bash, however I am unable to make it work in PHP. I have played around with both the exec() and the shell_exec() functions with no avail. I have tried the commands both manually i.e.: shell_exec(

问题 I am attempting to run a command as root from a php page, is there any way to run shell_exec( su - root -c 'apt-get update' ) (for example) and pass the password to the shell? Or is there another way to run a root command from php and pass the password to the command. I would prefer not to do the follow: edit the /etc/sudoers file; install the ssh2 php extension; 回答1: You could create a setuid wrapper for the command you want to run, and execute that wrapper instead: echo '#!/bin/bash' >

问题 I'm using a script to get files from my server. I'm using aria2 to download the files quickly and it works great but is there a way when the script is running to output what is happening in the command.

问题 I am working on a minecraft control panel in Ubuntu and thus I need to start/stop a .jar filewith shell_exec(); When I try commands like "whoami", the output is normal. But when I try this: shell_exec("screen -dmS mcsrv java -Xmx512M -jar /var/www/srv/craftbukkit.jar -o true nogui"); It does not do anything, I have checked the permissions too and www-data is the owner of the files 回答1: Try to redirect the standard error stream to stdout (by appending 2>&1 to the command), fetch that output
