php page starts bash script to run in the background and not timeout

I have seen this question on here before so I am sorry for the repetition but I have still not found an answer to my problem.

I have a bash script that takes a while to run. It needs to be passed variables set by a user on a webpage (don't worry there will be plenty of validation for security etc)

I can get the bash file to start but it dies after 20 seconds maybe when run from the webpage.

When run from the terminal.. runs absolutely fine.

Ok so I have the following:

$bashFile = shell_exec('./CoinCreationBashFile.sh "'.$coinName.'" "'.$coinNameAbreviation.'" "'.$blockReward.'" "'.$blockSpacing.'" "'.$targetTimespan.'" "'.$totalCoins.'" "'.$firstBitAddy.'" "'.$seedNode.'" "'.$seedName.'" "'.$headline.'" ');

Now this executes the bash file, but I read up about Shell_exec php with nohup and came up with the following:

$bashFile = shell_exec('nohup ./CoinCreationBashFile.sh "'.$coinName.'" "'.$coinNameAbreviation.'" "'.$blockReward.'" "'.$blockSpacing.'" "'.$targetTimespan.'" "'.$totalCoins.'" "'.$firstBitAddy.'" "'.$seedNode.'" "'.$seedName.'" "'.$headline.'" >/dev/null 2>&1 &');

But this still died after short time :(

So read up about set_time_limit and max_execution_time and set these to like 10000000 in the php.ini file.... Yet still no joy :(

Just want to run a bash script without it timing out and exiting. Don't really want to have to put an intermediate step in there but someone suggested I look at ZeroMQ to "detach worker from process" so I may have to go this route.

many thanks in advance

dont try runging a script via browser if they take more then 60 seconds instead try running this with SSH or as a cronjob.
