Modifying a ini file?

Chris_Evans

Hi there,
I've got an ini file which contains configuration settings for my site... it's intentionally not in the DB since the majority of it is related to the connection to the DB.

Anyway, I've got a form etc setup and would like to be able to modify this ini file.

So for example - if makes a change to 'serveraddress' - the script will go in and make a change to that value.

Since ini files are setup in a particular way, ie:

name = "value"
name2 = "value2"

etc etc

Is there any easy way of modifying them?

Read the file into memory with file(), walk through the array searching for the strings you're interested in, modify them, write them into the file again.

An example:

<?php

// -------------------------------------------
// Read INI File:
//
// This script reads in a file, INI style.
// It loads the setting names and their values into $config in an array
//
// To change or add a value, look at the example line.
//
// 	NOTES:	This script does NOT preserve blank lines.
//			Nor will it preserve lines that do not contain an equal sign.
//			Settings with blank values ARE preserved
//			Extra spacing on either side of a value is stripped 
//			Use quotes to preserve spacing (foo = "   bar ")
// -------------------------------------------

$file = file('config.ini');
$fp = fopen('config.ini', 'w');
$config = array();

$file = implode('', $file);
$file = explode("\n", $file);

foreach($file as $line) {

if(strstr($line, ' =')) {

	$split = explode(' =', $line);
	$config[$split[0]] = trim($split[1]);

}

}

$config['serveraddress'] = 'www.bradgrafelman.com'; // Example of changing/adding a setting

foreach($config as $setting => $value) {

if($value != NULL) fwrite($fp, "$setting = $value\n"); else fwrite($fp, "$setting =\n");

}

fclose($fp);
?>
