Help saving to a configuration file

[CazadorDeSue__os]

Hi,

I have a configuration file with this format

item = value
item2 = value2

I have no problem reading the file and getting each value per item, but i can get how to save to that file, for instance if i just want to modify an item, does anybody have an idea ??

Thanks.

Us vi commands to save you can use one like :x to save.

"config_file.txt" before:

item = value
item2 = value2
item3 = value3

Script:

function update_config_file($array, $file) 
{ 
    $lines = file($file); 
    foreach ($lines as $line) { 
        list($key, $value) = explode('=', $line); 
        $items[trim($key)] = trim($value); 
    } 
    foreach ($array as $key => $new_value) { 
        $items[$key] = $new_value; 
    } 
    $fp = fopen($file, 'w'); 
    foreach ($items as $key => $value) { 
        fwrite($fp, $key . ' = ' . $value . "\n"); 
    } 
    fclose($fp); 
} 

$new_config['item']     = 'new value'; 
$new_config['item2']    = 'new value2'; 
$new_config['new item'] = 'value'; 
$config_file = 'config_file.txt'; 
update_config_file($new_config, $config_file);

"config_file.txt" after:

item = new value
item2 = new value2
item3 = value3
new item = value
