finfo_open - Create a new finfo instance

Manual

Code Examples

finfo_open( [int$flags = FILEINFO_NONE], [string|null$magic_database = null] ): finfo|false

Object-oriented style (constructor):

public finfo::__construct intflagsFILEINFO_NONE stringnullmagic_databasenull

This function opens a magic database and returns its instance.

Parameters

flags

One or disjunction of more Fileinfo constants.

magic_database

Name of a magic database file, usually something like /path/to/magic.mime. If not specified, the MAGIC environment variable is used. If the environment variable isn't set, then PHP's bundled magic database will be used.

Passing null or an empty string will be equivalent to the default value.

Return Values

(Procedural style only) Returns an finfo instance on success, or false on failure.

Notes

Note:

Generally, using the bundled magic database (by leaving magic_database and the MAGIC environment variables unset) is the best course of action unless you specifically need a custom magic database.
