ini_read_real(section, key, default);
| Argument | Description |
|---|---|
| section | The section of the .ini to read from. |
| key | The key within the relevant section of the .ini to read from. |
| default | The value to return if a value is not found in the defined place (or the .ini file does not exist). Must be a real number. |
Returns: Real
You can use this function to read a number from an ini data
file. Ini files are split into sections and then each
section is subsequently split into key - value pairs.
So a typical ini file would look something like this:
ini_open( 'savedata.ini' );
score = ini_read_real( 'save1', 'score', 0 );
ini_close();
This will open 'savedata.ini' and set score to the value under 'save1' > 'score' in it, then close the .ini again. Should there be no value under 'save1' > 'score', or there no 'savedata.ini' file present, score will be set to 0.
