drupal_parse_info_file($filename)
Parse Drupal info file format.
Files should use an ini-like format to specify values. White-space generally doesn't matter, except inside values. e.g.
@verbatim
key = value
key = 'value'
key = 'value'
key =
'multi-line</p>
<p>value'
'multi-line</p>
<p>value'
'value'
@endverbatim
Arrays are created using a GET-like syntax:
@verbatim
key[] = 'numeric array'
key[index] = 'associative array'
key[index][] = 'nested numeric array'
key[index][index] = 'nested associative array'
@endverbatim
PHP constants are substituted in, but only when used as the entire value:
Comments should start with a semi-colon at the beginning of a line.
This function is NOT for placing arbitrary module-specific settings. Use
variable_get()
and variable_set()
for that.
Information stored in the module.info file:
- name: The real name of the module for display purposes.
- description: A brief description of the module.
- dependencies: An array of shortnames of other modules this module depends on.
- package: The name of the package of modules this module belongs to.
