How to monitor time remaining when running a php script looping?

I have a script that reads the directory and make a list of files, including some date about each file. A simple script like millions of others. Depending on the number of files in the directory and the availability of the server (is a shared hosting server), this will result in a timeout error.
Instead of just increase time_limit (might not even to be allowed), I was thinking about to monitor the time remaining each step of the way, I might suspend the task (exit the loop) return the list processed so far, and the process can be resumed from that point with a new request.
This can be done in php? How? What is the alternative excluding time_limit?

$end = time() + $limit; while(...) { ...; if( time() > $end ) { break; } }Where$limitis however long your timeout is expected to be, minus at least 1x whatever the longest possible time a loop iteration could take, minus time for post-loop code to complete. Ideally though you should ditch shared hosting and dive into public cloud so you could do something more productive like an asynchronous queue/worker system where you don't have to worry about individual request timeouts.

time will return seconds, not very accurate. Also I am worry about when the clock really start ticking. In my experience we might miss some precious time before to get the timestamp, some delay. Though we need something from the php core, if the server is counting time, the value must be somewhere, but I could not find it, don't know if actually exists a way to get it.

No, you cannot interrogate PHP to know how much time is remaining. This is a ridiculous problem to have, and you should try to not be in this situation at all in the first place.

I tried not do be in this ridiculous situation but I haven't got an answer yet, of course. This is a real problem of a real world, like listing a large number of files of a directory (and other challenges), you guys don't have an answer call my problem as "ridiculous situation"... sorry if this is embarrassing for you, will take my ridiculous questions elsewhere!

I gave you a perfectly workable suggestion, which you then rejected out-of-hand because seconds are "not very accurate". I even gave you a bonus suggestion of a better way to approach the general problem which doesn't land you in the Zone of Ridiculousness, and I'm just going to assume you're rejecting that out of hand as well.Have fun on your adventure.
