Excellent!
Yeah, that's nice, you limit it, but a little bit smart guy can set it
to whatever he/she wants :)

Hehehe yes, but as I said in a later message, only my application will be
accessing this page (hopefully), and the problem is not on the sending
server (which has lots of bandwidth) but on the receiving client, where my
downloading is killing all its small bandwidth.

Yes, I tried, this works, but I would like to control the send speed more, preferably via URL, as this programs will only be accessed by my desktop application, and I have full control of them.

all the bandwidth. The internet connection is slow (500kbps ADSL), and
they
have the critical applications running on it. It is no problem my download

limiting speed by using sleep in your script is a very bad idea. for a
350
MB file, with a 20 KB/s limit the script would take aprox. 5 hours. you
can see how this is totally wrong. even skyrocketing the timeout, it's
not
a good solution.
Use a web server mod for dynamic bandwidth limiting. See

Like most sites, someone needs to join up to use mine. I'm using a wee-bit-o-AJAX to pull some results from a database and display them dynamically. For the AJAX to work, it has to hit a script that's accessible from the htdocs tree right? Effectively it's just a (JavaScript initiated) GET URL request correct? For example, index.html calls http://example.com/gimmedata.php?query=foo That in turn returns a JS formatted array which is eval() in JS and rendered on the page. (over simplified I know) My question is, how do you protect gimmedata.php since it's sitting out there sans normal web headers and stuff? Can it include session_start() and do all that wonderful checking to make sure the user is logged in before just happily doling out my precious data? What is the proper, secure, sanctioned and AJAX/PHP blessed way to do this? I could set up a test environment and hack up something I'm sure -- and probably will if I get too impatient, but nobody seems to address this issue in any examples, they just do it as if information is *gasp* free.

Re: [PHP] PHP 6: Mysql with iso-8859-1 chars outputting utf-8: "Could not convert binary string to Unicode string"
You are right, I really don't know Unicode very much! :P
What I was trying to understand was, because unicode.runtime_encoding =
iso-8859-1, I tought that all internal operations were done in this
encoding, and only when outputting (unicode.output_encoding = utf-8) data
would be converted to utf-8. So to me, I did a mysql query with latin1, data
comes to my variables as iso-8859-1, I use them, and only when I echo'ed
them, they would become utf-8, from a iso-8859-1-to-utf-8-like function.
The strange thing to me, is the mysql_fetch_assoc function give this error
even before I accessed the field values, as I understanded from the above
explanation.
Did I understood it wrong?

Rangel

This is a question from a guy who does NOT really do Unicode very well...
If everything else in your entire system is iso-8859-1 (aka Latin1)
why are you making your output be utf-8?
Seems to me that that is where the conversion is probably taking place...
