I coding a simple uploader , but I stuck in one step , I wanna use the filter for my uploader so the uploader filters some extensions ,
I no the ways such as using mime to get the type of the content ,
<html>
<head>
<title>Uploader</title>
</head>
<body>
<form action="index.php" method="POST" enctype="multipart/form-data" >
<input type="file" name="myfile" />
<input type="submit" name="submit" value="Upload" />
</form>
<?php
$path = 'uploads/';
if(!is_dir($path))
{
mkdir($path);
}
if(isset($_POST['submit']))
{
$file_path = $path.$_FILES['myfile']['name'];
if(!eregi('', $_FILES['myfile']['name']))
{
if(!empty($_FILES['myfile']['name']))
{
if(move_uploaded_file($_FILES['myfile']['tmp_name'], $file_path))
{
echo 'Your file has been uploaded successfully!';
}
else
{
echo 'Error in uploading the file';
}
}
else
{
if(empty($_FILES['myfile']['name']))
{
echo 'You did not select any file ... .';
}
}
}
else
{
echo 'Oh, invalid file!';
}
}
?>
</body>
</html>
As you can see the code , here I used this function :if(!eregi('', $_FILES['myfile']['name']))
To filter the extension but I don't know this annoying regular expression stuff !!!!!! ( It's annoying me badly if you have any effective solution or program that I can give the regex and get the result introduce me with )I can also use something to walk through the array but I cut php for sometime and I've done some python stuff so I forgot how to walk through and array for example associative array and check the value of the array with specific value that I've inserted !
I mean for example I wanna check username and password in this array :
<?php
$username = 'Jacek';
$password = 'Betterphp';
$list = array('Jacek'=>':D','Jacek'=>':(','Jacek'=>'Why Jacek ?','Jacek'=>'Betterphp');
if($username == $list and $password == $list)
{
// Do something with jacek here 
}
?>
As you can see I wanna check username and password in this array how can I do this ?
