How to open multiple socket connections and do callbacks in PHP
- by Click Upvote
I'm writing some code which processes a queue of items. The way it works is this:
Get the next item flagged as needing
to be processed from the mysql
database row.
Request some info from a google API
using Curl, wait until the info is
returned.
Do the remainder of the processing
based on the info returned.
Flag the item as processed in the
db, move onto the next item.
The problem is that on step # 2. Google sometimes takes 10-15 seconds to return the requested info, during this time my script has to remain halted and wait.
I'm wondering if I could change the code to do the following instead:
Get the next 5 items to be processed
as usual.
Request info for items 1-5 from
google, one after the other.
When the info for item 1 is
returned, a 'callback' should be
done which calls up a function or
otherwise calls some code which then
does the remainder of the processing
on items 1-5.
And then the script starts over
until all pending items in db are
marked processed.
How can something like this be achieved?
