PHP system() call with variables

[cameron]

I'm looking to use the system (or exec) function to call a shell
script in UNIX. The following is the UNIX command line without PHP:

/home/public_html/VariableDirectory/myScript.ksh

VariableDirectory can be a number of different directories. Each of
them contain a copy of myScript.ksh.
So, we run the same script in different directories like this:

/home/public_html/FirstDirectory/myScript.ksh
and
/home/public_html/SecondDirectory/myScript.ksh

Now, regarding PHP:
I'm looking to have the web-user decide in which VariableDirectory
he/she wants to run myScript.ksh. Therefore, I'm looking to have a
system() call which looks something like the following:

system("/home/public_html/'".$_REQUEST[directory]."'/myScript.ksh");

However, this doesn't work. I've also tried to save
$_REQUEST[directory] as another variable and call it within the path.
For example,

$theDir = `echo $_REQUEST[directory]`;
system("/home/public_html/$theDir/myScript.ksh");

This doesn't work either. Does anyone know about the syntax for this
example of a system() call?

Thanks,
Cam

try putting a . in front and have the file set to 755 as in:

$theDir = `echo $_REQUEST[directory]`;
system("./home/public_html/$theDir/myScript.ksh");
or try

$theDir = `echo $_REQUEST[directory]`;
system("/bin/ksh /home/public_html/$theDir/myScript.ksh");
