带有/ arguments的PHP EXECUTE PERL

已采纳

I have the following php script which needs to call a perl script along with the arguments. If I have the paths correct, is there anything wrong with the syntax? The php and the perl on server side. The php receives information (the $GET['zipc'] thru a url. The perl script will produce an xml file back on the server. I keep getting unexpected 'exec' (T_STRING) on line 8. Thanks for any advice.

<?php
$zipc="-Z";
$lineup="-Y USA";
$fformat="-U";
$duration="-d 2";
$outfile="-o";
$ofile="guide.xml"
exec("perl http://www.myserver.com/myperl.pl" $zipc $_GET['zipc'] $lineup $fformat $duration           $outfile "http://www.myserver.com/myfile.xml");
print"FINALLY GOT TO END";
?>

EDIT: Well I thought it was all worked out. Now I get the following error: Fatal error: Only variables can be passed

According to the tech support people where I have the scripted hosted, I have to rewrite the line of code that contains the exec so as not to open connections. Kinda at loss on this one. Any advice?

EDIT 2: The problem lies in the array. From what I understand an array can not be passed as shown in the answer without generating an error. To fix the problem I concatenate the variable and the $_GET into one variable. Seemed to fix the problem.

    The second argument to the exec() function is an array. You have multiple syntax errors in your code because you have simply listed a bunch of variables without putting them inside of an array.

    Even if exec() did take a long list of parameters, which it doesn't, your code would still not work because you didn't separate them with commas.

    This should work (note the changes on lines 7 & 8):

    <?php
    $zipc="-Z";
    $lineup="-Y USA";
    $fformat="-U";
    $duration="-d 2";
    $outfile="-o";
    $ofile="guide.xml";
    exec("perl http://www.myserver.com/myperl.pl", array($zipc, $_GET['zipc'], $lineup, $fformat, $duration, $outfile, "http://www.myserver.com/myfile.xml"));
    print"FINALLY GOT TO END";
