Description

Procedural style

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

Object oriented style (constructor):

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

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

Examples

Example #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);

?>

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:
