PHP

Create a new fileinfo resource


finfo_open

finfo::__construct

(PHP >= 5.3.0, PECL fileinfo >= 0.1.0)

finfo_open -- finfo::__constructCreate a new fileinfo resource

Description

Procedural style

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

Object oriented style (constructor):

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

This function opens a magic database and returns its resource.

Parameters

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.

Return Values

(Procedural style only) Returns a magic database resource on success or FALSE on failure.

Notes

Warning

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.

Examples

Example #1 Object oriented style

<?php
$finfo 
= new finfo(FILEINFO_MIME"/usr/share/misc/magic"); // return mime type ala mimetype extension

/* get mime-type for a specific file */
$filename "/usr/local/something.txt";
echo 
$finfo->file($filename);

?>

Example #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);
?>

The above example will output:

 text/plain; charset=us-ascii
