Descrierea

Stil procedural

resource finfo_open ([ int $options = FILEINFO_NONE [, string $magic_file = NULL ]] )

Stil obiect-orientat (constructor):

finfo::__construct() ([ int $options = FILEINFO_NONE [, string $magic_file = NULL ]] )

This function opens a magic database and returns its resource.

Parametri

options

One or disjunction of more Fileinfo constants.

magic_file

Name of a magic database file, usually something like /path/to/magic.mime. If not specified, the MAGIC environment variable is used. If this variable is not set either, /usr/share/misc/magic is used by default. A .mime and/or .mgc suffix is added if needed.

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

Valorile întoarse

(Procedural style only) Returns a magic database resource on success sau FALSE în cazul eșecului.

Note

Avertizare

As of PHP >= 5.3.11 and >= 5.4.1 the magic datababase format has changed. Due to this, the internal mime database was upgraded. This affects especially the code where external magic is read in. Reading in magic files of the older formats will not work. Also, some textual representations of the mime types has changed, for instance for PHP would be "PHP script, ASCII text" instead of "PHP script text" returned.
