PHP help needed

[iosoft]

I need a help on PHP Coding.

The problem is, I want to save some configuration info in a .INI file in this format -

configuration.ini

param1=val1
param2=val2
param3=val3
param4=val4
etc.

How can I easily read/write the value of paramX from this file ?

<?php

$file = 'G:\projects\phpinfo.php';

if (file_exists($file) == false) {
die('It doesn\'t exist!');
}

$data = file_get_contents($file);

?>

This will get all the contents from the file. as for easily reading from the data.
You can use explode function to store data in array after every end-line or u can use comma. for e.g

para1 = ans1,
para2 = ans2,

for retrieving this we will have to use
$split = explode(",", $data);
Now $split is an array containing all the params.
$split[0] will be para1 = ans1

for writing

file_put_contents ($file, $data);

Note : file_get_contents() is not useful if you can find out the exact byte where ur params are stored as this will take away the need for exploding.

for writing after specified byte
$F = fopen("myfile.txt","a");

fseek($F, 11);

fwrite($F,"Imran");

fclose($f);

This method will only work if the number of bytes used will remain same in the constant.

I found a better and faster solution.... sharing with others

PHP parse_ini_file() Function

any means of writing it back or modifying the options?

I use a xml based one -> pXw4Pa - Poor XML Wrapper for PHP Arrays - v1.0

for reading and writing back the configuration settings.
