fread and fgets (network streams)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On the php.net you can read the following about fread:

"fread() reads up to length bytes from the file pointer referenced by handle. 
Reading stops when length bytes have been read, EOF (end of file) is reached, 
or (for network streams) when a packet becomes available, whichever comes 
first."

Is this true with fgets also? The "when a packet becomes available" part that 
is. I´m guessing "for network streams" means when the handler is not a local 
file but a remote file, right?

Why i´m i asking this? Well because i have a script wich now uses fread to get 
a remote file and would like to change this to fgets but i´m afraid i will bump 
into truble if i do since the part about waiting for a packed to become 
available sounds pretty important when dealing with remote files, right?

Thanks!
