Any good ideas for db searching?

[NeoGeo]

This database I've created is going to be filled with more than 1,000 entries. We want people to be able to search according to one of the entries properties, which is a numeric value.

I was thinking of doing a binary search by taking the numer value of each of the entries, putting them all into an array, sorting them, and then doing a binary search.

How slow is this going to be? With a thousand entries will php built-in sort() function run efficiently?

Is there a better solution than this?

Thanks,
Ben

If by "database" you mean a database like mysql, you need to learn SQL. Reading everything into an array and searching it would be slow.

Conversely, if you mean a flat file, you won't get any better than a linear search anyway - the time taken to read the file into an array is O(n), and you might as well search while you're reading (and stop when you find what you're looking for).
