Let's say I have a process "A" that loads a dynamic library "L".
Q: Is there a way to disable access to the "exec" functions to functions inside "L"?

Of the C library that contains the exec() functions as non-executable) that might get the effect you want version of exec() and system() that do what you want (or don't do), and either LD_PRELOAD it, or pass.

Why can I not change global variables from inside a function, using exec()? It works fine when the assignment statement is outside of exec(). Here is an example of my problem:
>>> myvar = 'test' >>> def myfunc(): ... global myvar ......

How about this:
>>> myvar =....
>>> myfunc contents.
exec 'myvar="boooh!"' in globals() ...
Per the docs , the exec statement takes two optional expressions, defaulting to globals/precise...:
>>> def myfunc(): ...

Echo "sed -i 's/NULL/\\N/g' ".$_REQUEST['para'].".sql";
The above statement works. But it fail when I use it in exec like this...
exec("sed -i 's/NULL//\/\/\N/g' ".$_REQUEST['para'].".sql");

You should escape backslashes with backslashes, not with forward slashes, like this:
exec("sed($_REQUEST['para'].".sql"); if(!is_writable($file)) throw new Exception('bad filename'); exec("sed.

You either need to turn safe mode off or add that directory to the safe_mode_exec_dir in PHP.ini
From the manual
Note: When safe mode is enabled, you can only execute files within the safe_mode_exec_dir.

They are similar to exec()..
After that - its simply a matter of writing, but did you consider the PHP core functions passthru() or system().
(...) is the only php function you can use to run ssh.

Use exec or ....
So if you have a large amount of processing that needs to be done quickly, exec() could be useful.
exec() allows you to use compiled code that is on your server, which would run faster than php, which is interpreted.

where pp is the string. It works fine, except for recursive calls, e. g., for example, this code is OK:

You would still need to use EXEC to do this.
