well i am new to PHP and i know some of the basics.. but i have a line in a file which is..


and my problem is that i want to add something infront of the semi-colon so that the sql limit is infinite.. is this possible if so how?

Infinity is a concept. If you can't put it on a piece of paper (and I'd like to see you try, other than symbologically), how do you expect a dumb processor to do it? Various types of variables have different maximum and minimum values. Consult your documentation. In PHP, for instance, on certain platforms, anything greater than 1.8e308 is larger than a double; it is, in essence, infinite.

if you want it infinate, a loop would probably be the best way to go.

What are you trying to do? Tell use your overall goal and we can help you with that. A loop would be the best thing to do if you wanted to do something over and over. My guess (from your variable name) you are trying to set the LIMIT on an SQL query. If thats the case, then you can simply leave the LIMIT statement out completely.

What in the devil does that mean?

He was assuming the original poster wanted to perform an action an infinate number of times... (like so)

DaWei

Helluva presumption -- few people do.

Another way to have a loop that goes in forever is something like this:
[PHP]
for ($i=0, $i=$i, $i++) {
// some code to be executed infinitely
}[/PHP]

So basically... the code is executed as long as $i is equal to $i, and obviously it's not going to not be equal to itself.

Why the hell would you want to use that .

If you want to keep track of how many times you've looped, just increase $i at the end of the block. This looks, IMO, just silly.

Ever hear of "for (;;);"? In the absence of optimization it's a more efficient coding of an infinite loop than "while (1);" Why? No expression evaluation.
