I think function's in bash doesn't accept any variables.
Incorrect, they take parameters just fine.
You call them directly, outside [ ], like you would an external program.
And your function should use return to give an integer value that if can use in this manner. It's like exit but only quits a function or sourced script instead of the entire program. Zero means success, nonzero means failure, just like the exit status of an external utility. Your EC variable trick works but such indirectness isn't necessary.

LEARN ABOUT PHP
finfo_open
FINFO_OPEN(3) 1 FINFO_OPEN(3)finfo_open - Create a new fileinfo resource
Procedural style
SYNOPSIS
resource finfo_open NULL ([int $options = FILEINFO_NONE], [string $magic_file])
DESCRIPTION
Object oriented style (constructor): finfo::__construct NULL ([int $options = FILEINFO_NONE], [string $magic_file])
This function opens a magic database and returns its resource.
PARAMETERS
o $options
- One or disjunction of more Fileinfo constants.
o $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 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 a magic database resource on success or FALSE on failure.
NOTES
Warning
The expected magic database format changed in PHP 5.3.11 and 5.4.1. Due to this, the internal magic database was upgraded. This
mostly effects code where an external magic database is used: reading an older magic file will now fail. Also, some textual repre-
sentations of the mime types has changed, for instance for PHP would be "PHP script, ASCII text" instead of "PHP script text"
returned.
Note
Generally, using the bundled magic database (by leaving $magic_file and the MAGIC environment variables unset) is the best course
of action unless you specifically need a custom magic database.
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
