finfo_open -- finfo->__construct — Create a new fileinfo resource

### Beschreibung

Procedural style

resource finfo_open ([ int `$options` [, string `$arg` ]] )

Object oriented style (constructor):

finfo
__construct ([ int `$options` [, string `$magic_file` ]] )

This function opens a magic database and returns its resource.

### Parameter-Liste

`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.

### Rückgabewerte

Returns a magic database resource on success or `FALSE` on failure.

### Beispiele

Beispiel #1 Object oriented style

`<?php
$finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); // return mime type ala mimetype extension
if (!$finfo) {
echo "Opening fileinfo database failed";
exit();
}
/* get mime-type for a specific file */
$filename = "/usr/local/something.txt";
echo $finfo->file($filename);
/* close connection */
$finfo->close();
?>`

Beispiel #2 Procedural style

`<?php
$finfo = finfo_open(FILEINFO_MIME, "/usr/share/misc/magic"); // return mime type ala mimetype extension
if (!$finfo) {
echo "Opening fileinfo database failed";
exit();
}
/* get mime-type for a specific file */
$filename = "/usr/local/something.txt";
echo finfo_file($finfo, $filename);
/* close connection */
finfo_close($finfo);
?>`
