Not sure where to start

joeblock

Can you please pont me in the right direction for this code:

I would like to read 6(or more) website pages AT THE SAME TIME.

So code would be

send a read request to first website

send a read request to second website

send a read request to last website

wait for respose.

As each response comes in display updated page.

Is it something to do with sockets?

Thank you

[man]fsockopen/man
[man]fread/man
Or
[man]file_get_contents/man

Note, you'll have to be careful about the timeout of PHP (30 seconds by default).

so I can have file_get_contents() 6 times .... would not this have to wait for each one to complete? I am looking for some code that would do all 6 simultaneously. The time to grab each is about 3 seconds each. so 5x3=15 seconds. Way to slow.

Any body have any examples?

What you want is threading... search php.net or google it

joeblock

Sorry to be so stupid but I cannot find an example (or even an explanation) of threading in php in google or php.net. Does anybody know of a simple good example? Can it even be done?

bpat1434

I'm sorry, I mistyped. I meant "fork"ing....

pcntl_fork

joeblock

Any examples?

bpat1434

Not really... I've never used it myself, just know it's there and it splits the current process into a parent and child.

You'd have to google for examples, or read the manual for [man]pcntl_fork/man

And also note:

It is not possible to use the function 'pcntl_fork' when PHP is used as Apache module. You can only use pcntl_fork in CGI mode or from command-line.
