I am using xampp on Windows platform.I am running a batch file with exec() command from my php script. It works well when user gives correct input and batch file completes its execution properly. But if the user give some wrong input and batch file remains unable to complete its execution, apache server hangs. Then I have to restart the server.

I want that the apache should not hang and it should not be dependent on the execution of the batch file. Just I should be able to correct my input instead of restarting the xampp.

Can anyone help?

Fix your batch file so it completes execution whether or not the input
is correct.

Ok. My batch file is as follows:

latex 1.tex
dvipng 1.dvi
copy 11.png question-preview

The first command do not runs successfully due to invalid input. Can you please suggest that how can I fix this batch file so that it should work independent of the input.

Ask the latex people. In the default configuration, on error latex switches to an
input prompt to ask the user to correct it.

Try prepending the 1.tex file with '\batchmode'.
