Hi all
Ive been try for sometime now, and too tried googling for an answer, to grab the STDOUT of a command. In this case the binary command is readbar The general output of readbar executed on its own is as so: Code 39->10005802 IATA 2 of 5->2 IATA 2 of 5->8 1 barcodes found
I basically need to grab this output.
Does anyone know how to send this to an array or varible.
You want to try shell_exec: http://www.php.net/manual/en/function.shell-exec.php
I haven't used readbar, but if it returns plain text then PHP should be able to get the return result, like:
$result = shell_exec('readbar');
Some things to consider though: do you want your webserver to have permission to execute shell commands? This COULD be a security risk, so be careful - watch your permissions. Another option is to run the readbar command from the command line and then pipe the result to PHP. I don't really know what you're trying to do here so I can't give better advice than that.
I too have tried the passthru function.
Kind Regards and thanks to anyone that can help Brent Clark
<?php
$dirfile = opendir("/var/www/html/davies/Scanned");
while(($row = readdir($dirfile)) == TRUE){
clearstatcache();
if($row != "." && $row != ".." && (substr($row,0,4) == "scan")){
$filearray[] = $row;
}
}
if($row == True){
closedir($row);
}
foreach($filearray as $var => $key){ system("/usr/sbin/readbar $key 2>%1"); }
?>
