exec() or system()

[Anon]

PHP 4.01, Apache 1.3.14, Redhat 7.0

The following line in a PHP script gives a parse error. The file is there and the same script has just written it (not a permissions problem).

exec(rm -f $voucher_print);

The same happens for system()

If the command within the brackets is quoted ie:

exec("rm -f $voucher_print");

Then no error, but it doesn't actually do anything either.

Can somebody tell me what I'm doing wrong here ?

Thanks

$voucher_print is probably an incorrect path. read the manual to find out that exec() needs a string as a param.

I usually use back ticks personally.

See the manual page for unlink().

Good thought, unlink will work fine for deleting the file.

The other job I'm trying to do with exec is to print the file ie:

exec(lp -d lp0 $voucher_print);

$voucher_print is a text file which the script has full access to.

Same problem, parse error.

Thanks again

You appear to have missed the other point which
is that the argument to exec or system needs to
be a string. Put the whole thing in double quotes
and you will be ok.
