Properties
The basic element contained in an INI file is the property. Every property has a name and a value, delimited by an equals sign (=). The name appears to the left of the equals sign.
PHP Code:
name=value
Sections
Properties may be grouped into arbitrarily named sections. The section name appears on a line by itself, in square brackets ([ and ]). All properties after the section declaration are associated with that section. There is no explicit "end of section" delimiter; sections end at the next section declaration, or the end of the file. Sections may not be nested.
PHP Code:
[section]
Comments
Semicolons (;) indicate the start of a comment. Comments continue to the end of the line. Everything between the semicolon and the end of the line is ignored.
