Re: File Writing / Reading Question

Hopefully you will not so many of them and remove them now and then. Then you can use file() function, it will read the file and return an array with one line in every array element. Then array_reverse() it. Miguel Angelo wrote:

Thankx i will

Plus, do you have any advice on how to read the file from back to start,

to

generate a html file starting with the most recent messages, also

generating

the html has fast has possible

A bit too complicated, or if you take it simple and read the whole file into an array, it could eat all awailable memory. Why don't you use database to store the log entries?

Not really a good point, i want a log that keeps messages like... database not available... so :) ..... no go i'm using a database (mysql) but this file is just for very critical messages can't i read a text file backwards ?
