How to find multiples of 1000 for comparison ?

290 Contributor
Hi,
I want to slow down my script so that
mySQL server can keep up.

I am counting the row numbers with $cnt
so after $cnt++; I want to add:

if ($cnt xxx ) sleep(2);

now xxx needs to be "any multiple of 1000" but I am
not sure how to code that.

As I am processing upto 30,000 records, I can not write out

if ($cnt == 1000 || $cnt == 2000 || $cnt == 3000 || $cnt == 4000 || etc etc up to 30,000)

Does anyone know how I can do this ?

Thanks

Eeeh:

I'm pretty sure it doesn't work that way :) PHP only goes as fast as MySQL can handle queries. If you MySQL queries are "too slow for PHP", your PHP script entirely will be slow. If your MySQL is very, very fast, PHP will be as slow as it's PHP code.

When sleep() is used, the entire script/program/application holds/sleeps/does nothing. MySQL doesn't gain by it. Use sleep only if you really want to do nothing (for example a socket timer, or an ajax chat timer, or something)

Hi, I need some help with stl maps. I am using a std::map that is sorted in a very special way. Therefore I am using my own sort function. That works fine. But this is only half the problem. Additionally "map.find()" should use a different comparison function. My map is like: map < myString, Whatever>

I'm a bit confused as to how the STL set works with the <setname>.insert() and <setname>.find() functions Compiler used : CodeWarrior 5.0 My intial interpretation was that I needed to overload the '<' for the insert() and '==' operator for find() however it doesn't seem to be the case In fact it seems to only need to overload the '<' operator for BOTH functions (it simply ignores the '==' operator)

Howdy, I am having trouble with the objectCategory=group member.Count attribute. I get one of three counts, a number between 1-999, no member (does not contain member property), or 0. Using LDIFDE as a comparison I get the same results. No members means just that, an empty group. Zero means that the DirectorySearcher.SizeLimit has been exceeded....

I have three values: UInt64 a, b, c, d; I need to determine if: (a*b) <=(c*d). Naturally, just doing the multiplication and comparing would tell me the result. However, the values could potentially overflow. For example, if: a = UInt64.MaxValue; b = 2;

Hi, I'm probably making this much harder than it needs to be, but I just can't think of how to do this. Each year, a database is created with all employees on it. I need to pull all the employees from the last five years and delete any duplicates. Each table has the exact same fields. So basically, I'm trying to combine tables from 2005, 2006, 2007, 2008 and 2009. Most of the employees will stay the same from year to year, so by combining...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
