ini_key_exists(section, key);
| Argument | Description |
|---|---|
| section | The section in the open .ini file to check a key in. |
| key | The key to check for. |
Returns: N/A
This function checks to see if a key exists in the currently
open ini. This is not a necessary check to prevent errors as, when
a key does not exist, reading from a non-existent key will just
return a defaulted value. It can be useful to see if an ini file
has saved specific data and a few other things, however.
ini_open('savedata.ini');
if !ini_key_exists('save1', 'name')
{
global.name = 'Player1';
}
ini_close();
This will set variable global.name to 'Player1' if no such key as "name" exists.
