PHP long running scripts in sequence

Question

I have the following problem : in a php script, I have to launch a first script, then a second one. The second one must not start before the first one has finished.

Problem : the two scripts are long-running (can take up to some hours). So, if I use file_get_contents on each script url, I can make the first one run (via set_time_limit 0), but the file_get_contents times out, so I have an error, and the second one never runs.

Note : those scripts run on localhost on a linux machine, on which I am admin. I can do whatever I need to make this work.

Thanks

Are you talking about PHP scripts here? Then why file_get_contents, and not include/require …? — misorude

Those are php scripts, which should be called via full url : it's in codeigniter, so it needs to respect the routing process. — MarvinLeRouge

You could try and pass a stream context into file_get_contents and specify the timeout via that. (Not sure if -1 for “no timeout” is a valid option.) But that might still run into problems with timeouts on the web server level or something. A script running that long should rather not be called via HTTP in the first place IMHO. — misorude

Execute them via command line, and chain them with &&, so the second one will fire only if the first has finished correctly

php script1 && php script2

Or chain with ; if you just want the second to trigger after the first, regardless of exit status

php script1; php script2
