Harddisk access

Kenshi

Hey all,

This might be the dumbest question ever written, but since I'm in doubt, I have to ask it. 🙂

A script of mine needs to do some stuff on my harddisk:

do some stuff
create a file
Access file
do some stuff with content
delete file
do some stuff

Now my question is: When my script gets to 1 and starts creating the file, does PHP stay at 1 until the OS (Linux in this case) is done creating the file, or does it move on as soon as the order for 1 has been issued?

I ask because I have A LOT of data being moved back and forth on my harddrive constantly, and I'm a bit worried that the script might end up at 3 and 4 before the file has even been created due to the massive traffic on my disks from other programs.

This is of course moot if PHP stays at 1 until it's done and then moves on. 🙂

I hope someone can help clear this up, and again: Sorry for asking such a stupid question.

Depends on your loops. If you are using for or while loops, they will stay in the loop doing 1, until the conditions are satisfied. Post a little of your code.

Hey,

There are no loops in the code. Things get done exactly as told by the numbers. I do a fopen() at 1 and I just need to know whether PHP moves on AT ONCE or if it stays there until the file has actually been created.

It will be created before it is moved. If there is a problem, you'll get an error, either on the create, or the move.

My God man, those are some pretty fast replies! 🙂

So even though the machine is very busy, PHP will wait patiently for the file to be created and then move on.. GREAT!

That was all I needed to know. Thanks a bunch for the help. 🙂
