Multithreading Issues

Copy linkTweet thisAlerts:
Nov 09.2005

hi,

does php guards me from multithreading issues, like writing to the same file ?

how it is implemented?
all the web servers has a thread pool, so php doesn’t run in a serial manner.

what will happen if two apache threads, for example, which runs two php requests will try to execute fopen on the same file?

thanks in advance,
Guy.

thanks.

@bokehNov 09.2005 — CPUs only do one task at a time. Multitasking allows steps of various tasks to be carried out in rotation giving the impression they are occuring at the same time. By the way php is a single thread language although of course multiple iterations of the same script can be run at the same time.

Success!
