Full Discussion: Php script prints values but not seen in browser

In short, if you run php script on command line, you will get something like this
Code:
[akshay@localhost tmp]$ php -r 'echo `whoami`;'
akshay

At the same time, If you're trying to trigger it from a web interface, you will receive output as
Code:
apache

You need to check following
  1. The user running the code (you vs apache)
  2. SELinux (disable SELinux)
  3. PATH
  4. If you are running some time consuming big programs, then max_execution_time or memory_limit in php.ini
    program executed by browser (with apache) and for cli (terminal - without apache) may have different values for max_execution_time or memory_limit - usual php.ini for cli has more memory and it could run for longer period of time
  5. Whether user apache has enough permission to read, write and execute programs/files

pidfilehack

pidfilehack(8)						      System Manager's Manual						    pidfilehack(8)

NAME

       pidfilehack - work around daemons that always fork

SYNOPSIS

       pidfilehack servicename pidfile command [parameters]

DESCRIPTION

       pidfilehack is used to work around daemons that insist on forking into the background, but that do write a correct pid file.

       pidfilehack  forks  the	actual	service,  then waits for the pidfile to be written. Once it can read the pid from the pidfile it will tell
       minit the real pid and quit.

USAGE

       usually pidfilehack is symlinked as run command of a service.

       servicename
	      the name of the service pidfilehack is installed for.

       pidfile
	      the filename to read the pid from

       command
	      the real command to start

       parameters
	      additional parameters for the command

	      A typical use of this command will look like this:

       /etc/minit/apache

       /etc/minit/apache/params
	      apache
	      /var/run/apache.pid
	      apachectl
	      start

       /etc/minit/apache/run
	      -> /sbin/pidfilehack

AUTHOR

       minit was written by Felix von Leitner and can be downloaded from his page at http://www.fefe.de/minit/

       This manpage was written by Erich Schubert <erich@debian.org> for the Debian GNU/Linux operating system.
