PHP如何检查fsockopen是否仍然好？

Question

When my script opens a connection in PHP with fsockopen and enters into endless while loop, how can I check inside the loop if connection is still good?

e.g. if my internet went out, the loop would still go, and that is bad. Thanks.

Answer 1

fgets() fwrite() and so on will probably fail. Did you try feof()?
