Edit PHP File

In my Admin area I display all the configuration values for my login script (eg. Site URL, Site Name etc...) After the Admin changes any of the values how do I then save the changes back to my configuration file overwriting the values that were already there?

Thanks.

I am creating a class at the moment which writes and saves configuration files similar to the httpd.conf file. I'll post it here when I'm done. You may also want to look at the PHP parse_ini_file() function. There are some good examples in the user comments of functions which also write ini files too.

This is the way i do it

create a file with the settings laied out in this way


setting=value
;comment

then in php have a function to read the list

PHP Code:

---

<?php 
$cfgfile = "scripts/config.txt";
//open the config file to read
$cfg = fopen($cfgfile,"r");

if ($cfg)
{
$data = fread($cfg,filesize($cfgfile));
//split by new lines
$lines = split("\n",$data);
//$lines is an array of settings and values
for ($d=0;$d<sizeof($lines);$d++)
{
if (substr($lines[$d],0,1) != ";")
{
$bits = explode("=",$lines[$d]);
$CFG[$bits[0]] = $bits[1];
// if its not a comment line
}
}
}
else
{
die("Cannot Read Config File ( $cfgfile )");
}
fclose($cfg)
// to use the settings its CFG[SETTING] the value will be stored in this 2D array
?>

---

try that :P

example would be

CFG['setting'] would equal "value"

EDIT : Removed extra )

made a class (1st one so dont laugh please)

here is how to use

PM me for help if u need k man

PHP Code:

---

<?php 
require_once 'config.class.php';
$config = new config;
$CFG = $config->read_config("config.cfg");
?>

---

$CFG = array of $CFG[Setting] settings names
functions in class
int add_setting($setting, $value, $file)
$setting = setting name
$value = setting value
$file = file to save to
This function will update if it already exsists

int delete_setting($setting, $file)
$setting = setting name
$file = file to delete from

int update_setting($setting, $newvalue, $file)
$setting = setting name
$newvalue = the new setting value
$file = file to save to
This function will create setting if not found

int is_setting($setting, $file)

array read_config($file)
$file = file to read from
will return array structure of object[setting] = value
