Re: reading lines from a file

Hi Anders, Well, of course the parser will consume full resources during several minutes. But I trust our old fellow George would do the parsing on a separate machine, and only do the LOAD DATA LOCAL on the production machine at night or such. My question was more as to whether there is a fundamental performance difference for file parsing between PHP at the command line and other languages such as Perl (which I don't know, so you won't have the opportunity to fire me because you won't hire me in the first place :-) Cheers Ignatius (self-employed idiot, currently pondering about firing himself) ____________________________________________ ----- Original Message ----- From: "Svensson, B.A.T.
