[PHP] updating several lines in a text file while leaving rest of file untouched

2001-09-10 Thread Kurt Lieber 

I have a configuration file that I use to store several variables and
would like to provide a web-based interface to update this form.  I'm
having some trouble replacing part of the file while leaving the rest of
it intact.

An example of the config file is:

$eventInfo[1][1] = First Event Title;
$eventInfo[1][2] = 145;
$eventInfo[1][3] = 300;

$eventInfo[2][1] = Second Event Title;
$eventInfo[2][2] = 50;
$eventInfo[2][3] = 1500;


What I can't figure out is how to selectively update certain lines,
while leaving all the other lines intact and without changing the
structure or order of the page. So, if I wanted to change
$eventInfo[1][2] to 150 and $eventInfo[2][3] to 2000, how can I do that
without mucking up the rest of the page?  I can update any one line by
using something like the following:

$fd = fopen($configFile, r+); //open the file and truncate it.
$newContents = eregi_replace(eventInfo\[1\]\[1\] =
\.*\;,eventInfo[1][1] = \ . $form_eventTitle . \;,$contents);
$newFile = fwrite($fd,$newContents);

but if I try to update more than one line, it causes the rest of my file
to get truncated or other weird things to happen.

Any help is appreciated.

you should seriously think about using a database for this.

agreed, except it's for a client who doesn't have database access at
their ISP and doesn't wish to pay more to get database access.  So, I'm
stuck using a text file for now.

Re: [PHP] updating several lines in a text file while leaving rest of file untouched

2001-09-10 Thread Jason Bell 

how much are they paying for their hosting?  I mean seriously you can
get a PHP enabled host that offers MySQL database for next to nothing these
days.


But, apart from that

you could read the file into an array, making each line an element within
the array. Modify what you need to modify, and then write the array back out
to the file, overwriting it with the updated information.
