Is PHP Suitable for This?

| Michael R. Copeland 2006-12-24, 3:59 am |
| I have an application I've developed in C/C++, written as a console
application. I need to port it to our Web page in such a manner that it
operates from a simple menu and searches a large text file database.
Currently, there are several text files being used together to identify
the existence of relevant information, as well as allow the program to
read "directly" (s /read) the data records. (It's a sort of "indexed
sequential" design.)
I've started working with 2 PHP books, and it _looks_ as though PHP
has the capability to do text file I/o in ways similar to my current
program. The data files are quite large (10MB), which is why byte
indexing is needed...as opposed to vast and slow sequential searching.
Is PHP suitable for something like this? If so, are there any sites
or NewsGroups I'd benefit from in this endeavor? TIA

| Depending on situation with the webserver, and complexity of your
console-application, but perhaps you could change a bit the
console-application so, that it would provide an interface usable to
php.
See www.php.net/manual/ref.exec.php

If the c++ app works well, why redesign it in php, just add few
functions to your c++ code and make it a php extensions:

10MB is actually small. When you get into the Gig range you are getting
into 'quite large' data files.

| Just like in C/C++
http://us2.php.net/manual/en/function.fgets.php
<?php
$handle = @fopen("/tmp/inputfile.txt", "r");
if ($handle) {
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
}
?>
