getting linux command exit code when executed via exec/system in php












1















my terminology my be off, but here goes:



lets assume one executes:



/bin/somecommand



using exec or system in php



the above command returns 'exit code' (this is the terminology that may be off) '1'.



is it possible to fetch this value via php?



if possible, do this without using a 'parent' bash script. we would love to be able to fetch this directly from php rather then having to run a parent bash script, and have that script echo out the exit code.



thanks!

          The manual for exec() shows that you can provide an optional third argument to collect the return status (exit code). Similarly for system(), a second optional argument.



          Example from that page:




          <?php
          
echo '<pre>';
          

          
// Outputs all the result of shellcommand "ls", and returns
          
// the last output line into $last_line. Stores the return value
          
// of the shell command in $retval.
          
$last_line = system('ls', $retval);
          

          
// Printing additional info
          
echo '
          
</pre>
          
<hr />Last line of the output: ' . $last_line . '
          
<hr />Return value: ' . $retval;
          
?>

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
