File Type Function

Talon21 · June 1, 2008

Hi all,

I'm new to PHP, at the moment I'm working on a script that will scan my Movies folder for example and will create a table with the necessary information. such as a link to IMDB etc...

I want to add a new <td> with the File Type information. here is the code:

<html>
<head>
<style>
.imdb{
font-family: verdana;
font-size:14px;
}
.imdb td{
border: 1px solid #EFEFEF;
}
.imdb th	{
border: 1px solid #EFEFEF;
}
</style>
</head>
<center>
<body>
<table class="imdb">
<tr>
<th>Movie</th>
<th>IMDB</th>
<td>
<?php

//scaning the movies folder

$dir    = 'G:\Home\Movies';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);
for ($a = 0 ;$a < count($files1); $a++)

//if conditinon to delete the "." and ".." folders from the table

if ($files1[$a] == ".")
echo "";
else if ($files1[$a] == "..")
echo "";
else	
//echo the movie table
echo '<tr><td>'."$files1[$a]".'</td>
      <td><a href="http://www.imdb.com/find?q='."$files1[$a]".'&sourceid=mozilla-search">IMDB</a></td></tr>';


?>		  
</tr>
</td>
</table>
</body>
</center>
</html>

What do you mean by "File type"? It's extension? It's MIME type? Be a bit more specific please.

Orio.

Sorry I meant file file extension for example : .avi , .srt , .mp3 etc...

Thanks

Use pathinfo():

<html>
<head>
<style>
.imdb{



font-family: verdana;



font-size:14px;
}
.imdb td{



border: 1px solid #EFEFEF;
}
.imdb th



{



border: 1px solid #EFEFEF;
}
</style>
</head>
<center>
<body>
<table class="imdb">
<tr>
<th>Movie</th>
<th>IMDB</th>
<td>
<?php

//scaning the movies folder

$dir    = 'G:\Home\Movies';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);
for ($a = 0 ;$a < count($files1); $a++)

//if conditinon to delete the "." and ".." folders from the table

if ($files1[$a] == ".")



echo "";
else if ($files1[$a] == "..")



echo "";
else



$info = pathinfo($files1[$a]);
//echo the movie table



echo '<tr><td>'."$files1[$a]".'</td>



      <td><a href="http://www.imdb.com/find?q='."$files1[$a]".'&sourceid=mozilla-search">IMDB</a></td>



      <td>Extension: '.$info['extension'].'</td></tr>';






?>





  
</tr>
</td>
</table>
</body>
</center>
</html>

Edit: Don't know why the layout between the [ code ] tags got so messed up.

Hi the badbad

I copy and paste the code to my script and it's seems that it's not working all I'm getting is an empty table.

Movie IMDB

IMDB Extension:

Is it just the extension code that returns blank, or is the whole thing broken?

Just found you had some errors in your table construction. You really should indent your code too. I cleaned it up a bit, try this:

<html>
<head>
<style type="text/css">
	.imdb{
	font-family: verdana;
	font-size:14px;
	}
	.imdb td{
	border: 1px solid #EFEFEF;
	}
	.imdb th{
	border: 1px solid #EFEFEF;
	}
</style>
</head>
<body>
<center>
<table class="imdb">
	<tr>
		<th>Movie</th>
		<th>IMDB</th>
		<th>Extension</th>
	</tr><?php
//scaning the movies folder
$dir    = 'G:\Home\Movies';
$files1 = scandir($dir);

for ($a = 0 ;$a < count($files1); $a++) {
//if conditinon to delete the "." and ".." folders from the table
if ($files1[$a] == "." || $files1[$a] == "..") {continue;}

//load file info into $info
$info = pathinfo($files1[$a]);

//echo the movie table
echo '
	<tr>
		<td>'.$files1[$a].'</td>
		<td><a href="http://www.imdb.com/find?q='.urlencode($files1[$a]).'&sourceid=mozilla-search">IMDB</a></td>
		<td>Extension: '.$info['extension'].'</td>
	</tr>';
}
?>
</table>
</center>
</body>
</html>

It's working now, the problem is that it's not giving me the extension for the files inside the folder.

thebadbad · June 2, 2008

Can't see why it shouldn't work. $files1[$a] contains something similar to 'filename.avi', right?

thebadbad · June 2, 2008

Else you can use explode to get the extension:

<html>
<head>
<style type="text/css">
	.imdb{
	font-family: verdana;
	font-size:14px;
	}
	.imdb td{
	border: 1px solid #EFEFEF;
	}
	.imdb th{
	border: 1px solid #EFEFEF;
	}
</style>
</head>
<body>
<center>
<table class="imdb">
	<tr>
		<th>Movie</th>
		<th>IMDB</th>
		<th>Extension</th>
	</tr><?php
//scaning the movies folder
$dir    = 'G:\Home\Movies';
$files1 = scandir($dir);

for ($a = 0 ;$a < count($files1); $a++) {
//if conditinon to delete the "." and ".." folders from the table
if ($files1[$a] == "." || $files1[$a] == "..") {continue;}

//split string at dots to get extension
$info = explode('.', $files1[$a]);

//echo the movie table
echo '
	<tr>
		<td>'.$files1[$a].'</td>
		<td><a href="http://www.imdb.com/find?q='.urlencode($files1[$a]).'&sourceid=mozilla-search">IMDB</a></td>
		<td>Extension: '.end($info).'</td>
	</tr>';
}
?>
</table>
</center>
</body>
</html>

I think that the reason that's not working it's because inside the Movie folder $dir = 'G:/Home/Movies'

each movie is located on a separate folder.

thebadbad · June 2, 2008

Oh, I didn't know that. So the title you're echoing is from the directory I see. To get the extension, we then have to scan each directory separately. I guess each movie directory contains a bunch of files (movie + subtitles and such), so we have to distinguish the movie file from the rest of the files.

I would check if the current "file" is a directory (is_dir()); if yes then run another scandir(), then run through each file (foreach()) and set the extension if it's one of the following: avi, mpg, mpeg, mp4, mov, wmv (just tell me if you want help adding more types):

<?php
//get file extension of video file inside the movie directory
if (is_dir($dir.'\\'.$files1[$a])) {
	$files = scandir($dir.'\\'.$files1[$a]);
	foreach ($files as $file) {
		$info = explode('.', $file);
		$ext = strtolower(end($info));
		if (in_array($ext, array('avi', 'mpg', 'mpeg', 'mp4', 'mov', 'wmv'))) {
			$extension = $ext;
			break;
		}
	}
}
?>

Whole script:

<html>
<head>
<style type="text/css">
	.imdb{
	font-family: verdana;
	font-size:14px;
	}
	.imdb td{
	border: 1px solid #EFEFEF;
	}
	.imdb th{
	border: 1px solid #EFEFEF;
	}
</style>
</head>
<body>
<center>
<table class="imdb">
	<tr>
		<th>Movie</th>
		<th>IMDB</th>
		<th>Extension</th>
	</tr><?php
//scaning the movies folder
$dir    = 'G:\Home\Movies';
$files1 = scandir($dir);

for ($a = 0 ;$a < count($files1); $a++) {
//if conditinon to delete the "." and ".." folders from the table
if ($files1[$a] == "." || $files1[$a] == "..") {continue;}

//get file extension of video file inside the movie directory
if (is_dir($dir.'\\'.$files1[$a])) {
	$files = scandir($dir.'\\'.$files1[$a]);
	foreach ($files as $file) {
		$info = explode('.', $file);
		$ext = strtolower(end($info));
		if (in_array($ext, array('avi', 'mpg', 'mpeg', 'mp4', 'mov', 'wmv'))) {
			$extension = $ext;
			break;
		}
	}
}

//echo the movie table
echo '
	<tr>
		<td>'.$files1[$a].'</td>
		<td><a href="http://www.imdb.com/find?q='.urlencode($files1[$a]).'&sourceid=mozilla-search">IMDB</a></td>
		<td>Extension: '.$extension.'</td>
	</tr>';
}
?>
</table>
</center>
</body>
