[PHP] File Random Access
I never noticed before...there is no easy way to perform random-access read and WRITE on a file. I vote/recommend/suggest that this most basic functionality be added to the next release of PHP. This would not be an enhancement; rather, it is correcting a serious flaw.

I haven't tested this, so I may be missing something, but doesn't
fopen('filename', 'rb+') or fopen('filename', 'ab+') allow for this?
Cheers!

RE: [PHP] File Random Access
Rick, If you have a file that is to large to simply read into memory, do your inserts and then write back out then you need to move it to a database. Cluttering up the main code base with random flat-file reads and writes is not necessary. If you seriously need it then you can do as suggested, create a new file, read from the old file, insert at the proper place, close, delete, rename, rinse, repeat. If you think about it, that's what the php developers will have to do to accommodate your request. (assuming again that your file is too large to simply fit in memory.) It may be a need for you but in my 2 years of using PHP, you are the first person I've seen ask for it. Therefore I don't think it qualifies as a serious flaw.

Re: [PHP] File Random Access
You are correct. In fact, simply r+ works; I just tried it.
Thanks

Thanks Yes, but that's not guaranteed to be binary-safe on Windows -- if your data happens to include null bytes, you might get unexpected file truncations (I think...)! Cheers!
