Exec problem

[xavikevicious]

i have one problem with exec function. i want to execute unzip like this:

exec("/usr/bin/unzip Analisi_Programa_Anticopia/Fitxer/fitxerAnticopia.zip -d Analisi_Programa_Anticopia/Fitxer/practiquesComprimides";

in server my working directory is script/ . Inside this there is Analisi_Programa_Anticopia/ directory. if i write these sentence ( unzip Analisi_P........ ) in server's shell the unzip sequence is ok.

which is my problem? is it possible that my server don't accept exec function??have i change anything in my php.ini file?

thanks in advance

pd-all directories and files have all permissions. My php version is 4.

What is the error you are getting?

[xavikevicious]

hi!

is there any way for looking at the runtime errors ??

i don't see any error in my screen. my .zip archive doesn't unzipped. Do you undestand me?

You can grab the output of the exec command by passing it an extra parameter.


exec("/usr/bin/unzip Analisi_Programa_Anticopia/Fitxer/fitxerAnticopia.zip -d Analisi_Programa_Anticopia/Fitxer/practiquesComprimides", $output);

print_r($output);

hi

print_r($output) give me an "Array()" sollution on my screen.

now im going to look at how i can to pass to string this array.

thanks

Print_r will also print the contents of the array. In this case the program did not have any ouptput, therefore, an empty array. Try passing the program absolute paths to the files you want to extract instead of relative.

with an implode function ;)

well, with print_r($output): $output is empty. there aren't any!!

hi again,

exec("/usr/bin/unzip /users/home/alumnes/TM/tm05609/scripts/Analisi_Programa_Anticopia/Fitxer/fitxerAnticopia.zip -d /users/home/alumnes/TM/tm05609/scripts/Analisi_Programa_Anticopia/Fitxer/practiquesComprimides",$out);

with absolute paths and my $out output is empty too.

do you know anymore else??

My guess is that there is an error but it is being sent to the error sream instead of the standard output stream. Try redirecting the error stream to the standard output and see what happens:


/usr/bin/unzip /users/home/alumnes/TM/tm05609/scripts/Analisi_Programa_Anticopia/Fitxer/fitxerAnticopia.zip -d /users/home/alumnes/TM/tm05609/scripts/Analisi_Programa_Anticopia/Fitxer/practiquesComprimides 2>&1

hi again,

my error is:

Array([0] sh: /usr/bin/unzip no such file or directory).

unzip is installed on my server and the same sentence is written for me on command line and the unzip is successful there.

I think apache may be chrooted into a particular directory. Are you hosting off your own server or a shared server? You can get around this by finding a directory to which Apache/PHP has access to and copy the unzip program into it, you may also have to copy any shared libraries it uses too.

[xavikevicious]

i have look at my php.ini file and the sentence 'doc_root' has a 'no value' value , my php hasn't got initial directory. Im hosting off a shared server ( its an university server with lots of users ) and i cant to install unzip nowhere because im not an administrator. :(

Find a directory you know PHP has access to and copy the unzip binary to that directory, you don't need to be an administrator to do that.

[xavikevicious]

thanks for all

I would be interested to know whether you have solved the problem. :wave:

Last question:

I have been looking for on net a binary unzip but for Unix there are several versions ( one for each Unix OS). My question is: How i can to know which Unix OS i have in my server?? Is there any command for this??

Maybe phpinfo() help you?
Or you can use getenv() function?
Or you can use _SERVER array?
