ini_key_exists

This function checks to see if a key exists in the currently open ini and will return true if it does or false otherwise. 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 default value. It can be useful to see if an ini file has saved specific data and a few other things, however.

Syntax:

ini_key_exists(section, key);

Returns:

Boolean

Example:

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.
