[PHP] Attempting to use 'passthru' or 'exec' function

2005-01-23 Thread Andre Dubuc 
Hi, 

I'm trying to output a text file from a pdf file using an external function, 
pdftotext, using either PHP's 'passthru' or 'exec' functions.

The following code sort of works (at least I see localhost busy doing 
something for about three seconds, but  the expected output of 'content.txt' 
is empty. I used an idea found on the mailing list: I actually got some 
activity with 'sudo desired_function arg1 arg2'.

File permissions are set wide open (apache:apache 777), safe_mode=off.

What am I doing wrong? (Btw, the pdftotext function works fine on 
commandline).

?php

$currentPdf = 2005-01-v2.pdf;
//print $currentPdf;

if (file_exists($currentPdf)) {
passthru(sudo /usr/bin/pdftotext /var/www/html/2005-o1-v2.pdf.txt 
/var/www/html//current.txt);
}

/* Also tried the following using 'passthru' then 'exec':
$pdf = file_get_contents($currentPdf);
//print brbr$Pdf;

passthru(sudo pdftotext /var/www/html/2005-o1-v2.pdf.txt 
/var/www/html/current.txt);
*/

$current = current.txt;

print brbrCurrent Text: $current;
$string_text = file_get_contents(current.txt);
$new_text = nl2br($string_text);

?

Any help, pointers, admonitions gratefully accepted,
Tia,
Andre

Have you tried using the backtick (``) operator?  I don't know if it makes
any difference, but it might be worth a try...

HTH,

1) What does your php error log say?
2) Is there any reason you're using sudo? Do you know how it works and have 
you configured sudo correctly?
3) Commands like passthru() and exec() allow you to check the return value of 
the system command being executed -- use it.
