php cli can't run php file outside its path

asiandude · 12-09-2008, 09:23 AM

Hello People! I am new here

I hope someone could help me with a scripting problem...

ok here goes..

I have many php files i want to run periodically using php cli and they are located all over the place so i decided to seek them out for execution.

This is what i intend to run in cron

Code:

find /home/ -type f -name "filename.php" -print | xargs php

the problem is my php files do not use full path so if i run them outside their path i will get the following error:

Quote:

Warning: require_once(../../config.php): failed to open stream: No such file or directory in /home/somepath/where/thefile/located/filename.php on line 3

if i go to the path where the php files are located and type 'php filename.php' it will run just fine.

I do not want to change the path in all my php files. So is there a way to run my phpfiles as if i run them from their path?

Instead of piping the find results to "xargs php" pipe them to "xargs mywrapper". In "mywrapper", trim the path off the filename, do a cd to that path, and execute the file there.

As CDollmont has said you need to change the directory before executing. Another approach would be to change the include_path, this can be done by changing the php.ini file or on the fly with the set_include_path() function. This is probably of more interest in the future, where a line such as set_include_path(get_include_path() . PATH_SEPARATOR . getcwd()); in your main function may sort out this sort of problem for you.

Thanks guys... i tried to do a pipe xargs cd on find directory and got

Quote:

find: `cd': No such file or directory

i am sure the output path is correct.. not sure why cd doesnt work.

pardon me for being a newbie.

I thought the correct expression is:

Code:

find /home/ -type f -name "filename.php" -exec php {} \;

Additionally, when writing PHP you should make *no* assumptions as from where it is executed. Imagine you would execute 'ls' and it would complain it could not find the directory for its includes! (I know there aren't any)

You should specify the absolute path of the includes in your php source code.

This might help you as well:

Code:

-execdir command {} +
              Like -exec, but the specified command is run from the subdirectory  containing
              the  matched  file,  which  is not normally the directory in which you started
              find.  This a much more secure method for invoking commands, as it avoids race
              conditions  during  resolution of the paths to the matched files.  As with the
              -exec action, the ‘+’ form of -execdir will build a command  line  to  process
              more than one matched file, but any given invocation of command will only list
              files that exist in the same subdirectory.  If you use this option,  you  must
              ensure that your $PATH environment variable does not reference ‘.’; otherwise,
              an attacker can run any commands they like by leaving  an  appropriately-named
              file  in a directory in which you will run -execdir.  The same applies to hav‐
              ing entries in $PATH which are empty  or  which  are  not  absolute  directory
              names.

The excerpt is from the man page.
